Can I just comment on how fantastic it is to have not only the knowledge but also the rich vocabulary that goes with this talk, its truly very engaging
I could listen to Matt Walker talk all day long, which is quite handy with this long form structure. It’s great seeing him so accomplished considering he grew up 15 minutes away from me.
Really appreciate this episode, Mathew finally addressed the issue with elderly and insomnia community. It’s the best and the most clear explanation of sleep deprivation & insomnia episodes ever. Thank you Andrew for doing this podcast.
Great to see university professors telling the public about advances in science, and focusing on public outreach and engagement. 👍 Public engagement with research is a two-way process with the goal of generating mutual benefit between the public and researchers and ultimately enhancing the quality or impact of research.
Matt’s voice is all I need to fall asleep. I even avoid listening to his wonderful explanations while having my morning coffee. His voice is so comforting.
I have been watching Huberman series for almost 5 hours now! Come on, how one man can bring worldwide scientists to impart this barrel of knowledge. I love your aura with Dr. Matt Walker! Love the duo here! My favourite till date, Dr, Huberman.
Being able to work from home I can sleep from 10:30 pm to 6:30 am and from 1:30 to 2:00pm almost daily. This has improved my life so much (concentration, energy, productivity, skin quality)
Throughout this guest series it is clear that temperature and temperature regulation have profound importance for our physiology. This is certainly the first time i've heard it come up again and again. Maybe a podcast on thermoregulation and/or dysregulation would be good.
Great suggestion. I would love to hear a podcast (by Dr Huberman, of course) all about thermoregulation, especially the limits of human thermoregulation, and what happens to the body in uncompensable heat stress (e.g., development of exertional heat illnesses).
@@Lili-xq9snyour body will lower your body temperature after the hot shower and therefore sleep better since you need your body temperature to drop in order to sleep.
Your podcast, literally change my life, some podcast that are 3-2 hours long, I watched them multiple times. Your explanation is very clear sir. I always amaze to every podcast I hear. It feels like you accompany me walking. I listen to them while taking my walk outside. You provide all the information for me, so I don’t really need to waste more time, looking them out myself. THANK YOU
Need a podcast about overnight shift workers best protocol to be as healthy as possible workout routine nutrition how to stay awake and alert through the shift etc
I'm pretty sure that's going to be part of this series. The bottom line is though, that it will be about minimizing damage. You cannot avoid that fact that there is nothing you can do that will change the fact that shift work wrecks havoc on the body.
06:14 🛌 Different types of sleep exist across the lifespan, from highly polyphasic in infancy to more monophasic in adulthood. 16:46 🧠 REM sleep plays a crucial role in brain development, particularly in stimulating the growth of connections within the brain during infancy. 19:47 🔄 Sleep patterns stabilize around age five or six, with a consistent ratio of about 20% REM sleep to 80% non-REM sleep throughout adulthood. 22:04 🌞 Traditional societies and cultures may have different sleep patterns, including siesta-like naps and waking patterns determined by temperature rather than sunrise. 23:24 🌙 Sleep schedules vary based on chronotypes, with some people naturally inclined to sleep and wake earlier, while others prefer later sleep times. 25:13 🔄 Variability in sleep preferences across individuals reduces collective vulnerability, ensuring someone is always awake to monitor the environment. 29:11 🧬 Chronotypes, while influenced by genetics, can be modified by life circumstances and exposure to light. 33:00 ⏰ Biphasic sleep patterns include siesta-like naps and segmented sleep, with historical examples of first sleep and second sleep. 39:29 🛌 Body position affects sleepiness, with lying down facilitating thermal dissipation and core body temperature drop, promoting sleep onset. 42:02 📚 Napping can enhance learning and memory consolidation, with benefits observed in emotional regulation and cognitive function. 46:02 💤 Naps improve attention, focus, decision-making, and mood, but may reduce sleep pressure, potentially affecting nighttime sleep. 47:11 💤 Napping can release built-up sleepiness, but it's advised against for those with insomnia as it may hinder nighttime sleep quality. 48:46 🕒 Napping late in the day can reduce sleepiness before bedtime, akin to snacking before a meal, so it's recommended to avoid napping too close to bedtime. 53:20 🕑 Optimal nap duration for most people aiming for a quick reboot and improved alertness is around 20 minutes, as it provides benefits without causing sleep inertia or grogginess. 56:32 🌙 Longer naps offer more benefits, but they come with the tradeoff of potential sleep inertia, where one may feel worse initially upon waking. 57:27 🚫 Avoid napping too late in the day, generally recommended not to nap after 3:00 p.m., to prevent interference with nighttime sleep. 01:00:54 🤔 Napping isn't necessary for everyone, but if interested, mimicking nighttime conditions can increase the likelihood of a successful nap, focusing on factors like darkness, quiet, and comfort. 01:04:04 💭 Exploring alternative states of consciousness, like meditative or "linal" states, could offer benefits similar to napping, potentially involving local deep sleep in the brain. 01:08:23 🚀 NASA's research on napping showed significant boosts in alertness and productivity, leading to the adoption of "power naps" to enhance performance, particularly in astronauts and pilots. 01:10:49 🛫 Prophylactic napping, or "power naps," was a term coined for optimal nap placement during long-haul flights, suggesting early napping sustains alertness throughout the flight. 01:13:35 🧘♂ Yoga Nidra, or "yoga sleep," offers mental and physical restoration through relaxation, but misconceptions exist. "Non-sleep deep rest" protocols maintain Yoga Nidra benefits without mystical elements. 01:15:46 🌙 Late-day naps can disrupt nighttime sleep, leading to fragmented sleep and difficulty falling back asleep after waking during the night. 01:19:23 ⏰ Insomnia sufferers are advised to avoid napping, as it can exacerbate nighttime sleep struggles, worsening sleep quality and perpetuating sleeplessness. 01:21:53 🛌 Older adults' daytime napping habits can reflect poor nighttime sleep quality, potentially indicating health risks and higher mortality rates rather than being a direct cause. 01:29:24 ☕ Caffeine functions as an adenosine antagonist, blocking adenosine receptors in the brain to mitigate sleepiness temporarily, explaining the concept of a "caffeine nap" or "nappuccino." 01:32:39 ☕ Caffeine's initial boost after consumption within the first few minutes is not due to its effects but rather the temperature of the drink, usually warm, which contributes to an immediate sensation of alertness. 01:35:51 🕒 Structuring naps strategically around caffeine intake can mitigate sleep inertia, creating what's known as a "caffeine nap" or "nappuccino." Consuming caffeine just before a nap allows its effects to coincide with waking up, providing a dual benefit. 01:41:24 💤 Adenosine clearance primarily occurs during deep non-REM sleep when the brain is less metabolically active. Other activities like exercise or exposure to light may not directly affect adenosine levels but can promote alertness through different mechanisms. 01:43:26 🌅 Delaying caffeine intake by 90 to 120 minutes after waking can help offset the afternoon crash and potentially improve sleep quality by avoiding interference with adenosine clearance and allowing for a clearer assessment of sleep restoration upon waking. 01:55:00 ☕ Caffeine and alcohol use can form a cycle of dependency affecting sleep, with caffeine as an upper in the morning and alcohol as a downer at night. 01:55:37 💤 Moderate caffeine intake by not exceeding three cups of coffee per day and being mindful of sensitivity, adjusting timing accordingly. 01:57:03 🛌 Various nap types, including caffeine naps, offer benefits, with additional potential from combinations like nap plus cold face washing or bright light exposure. 02:01:50 🔄 Polyphasic sleep, popularized by biohacking, involves splitting sleep into multiple phases within a 24-hour period but lacks scientific support for health benefits and may have negative consequences. 02:09:53 ⚠ Polyphasic sleep schedules, historically traced to 1943, pose risks including decreased total sleep, poor sleep quality, reduced REM sleep, and impaired cognition and health, with potential safety concerns like increased risk of accidents.
Yes, I found the 16:46 timestamp interesting too. My daughter was born with reflux and basically didn't sleep for the first year/ year and a half of her life. She was later diagnosed with ADHD and I often wonder if that inability to sleep (because of the pain she was in) had something to do with it. It would be an interesting study to look at ADHD and reflux in infancy.
Thank you for hosting this wonderful podcast. I have listened to everything on this sleep series. Dr. Matt reiterates the importance of QQRT, I want to know if regularity and timing is as important when the body has the flu, is injured, or ailing in some way? I always feel inclined to sleep as much as possible when I am injured or unwell. Thanks again, and keep up the great work!
😂Thank you both again!! I listened to all the information and suggestions earlier yesterday morning, and have been implementing them (the cold water vs warm water on face and palms was a huge help too, because others in the same field have been telling me to splash cold water on my face all the time, not explaining the timing differences that Dr. Walker explained so thoroughly, and it helps me understand why I was wide awake after splashing the wrong temperature of water on my face at night and couldn't sleep, you have no idea how much you and your team and explanations are appreciated!!) Both of you and your teams are all amazing!!❤❤ I slept from 10pm to 5 am, only awakening once at 3am; fell right back to sleep. yay!!!
As someone struggling with sleep, especially during pregnancy and with small kids waking you during the night, it would be very interesting with an episode focusing on pregnancy/parenting sleep. It would also be very interesting with an episode focusing on sleep in psychiatric conditions (ADHD, autism etc.), which at least to me appears to be an unrecognized topic (i.e., sleep issues in these conditions).
In Spain, many people still take siestas in the summer when it's really hot, and work schedules switch from split shifts to continuous ones. For the rest of the year, the siesta is replaced by coffee and 2 hours of unproductive work.
I love you both and appreciate how generous you are to share your knowledge with us. I'll put this series in my list of "must listen". thank you, from San Diego
Dr. Huberman, I greatly appreciate your work on neuroscience and sleep. Given your expertise, I’m seeking advice on managing sleep for firemen who often have challenging schedules. We typically work 24 hours on, followed by 24 hours off, repeating this cycle twice, and then taking either four or six days off. This schedule can make maintaining a regular sleep pattern difficult. Could you provide insights or recommendations on how to best manage and optimize sleep under such conditions? Specifically, are there any strategies for adapting our circadian rhythm or managing sleep debt effectively during our working days and recovery days?
Your job is incredibly risky for so many reasons. You will need to spend your life off work trying to minimize all of the health risks. Once you understand that your job is really dangerous for you even when not at a fire, your life changes. Blackout curtains, strict routines, including diet and hydration, mental health strategies, etc. It will be very difficult to spend time with people who aren't living that schedule.
What a fantastic series; thank you both for pulling it together! I was surprised however that significant timezone shifting wasn’t really discussed in any of the 6 episodes. For those vacationing, or required by work, in locations between 6 and 18 hrs off of their home timezone, it would be interesting to hear what best practices might be for powering through a trip, adapting as quickly as possible to the new timezone, caffeine use for both short and longer-term visits, and importantly, decision making when jet-lagged in more significant offsets. How is decision making/learning impacted when shifting to a timezone 10 hrs off of your usual, and then back again? Thanks!
You make my life so easier. Can not thank you enough. Plus the process of delivery of knowledge by both of you is a real joy for eyes and ears, and brain. You are stalwarts of truth and generosity. Bravo! Щиро дякую! Слава Україні!
Thank you for this series. I leave for work at 3am and start my work day at 4am. I've always had a hard time sleeping and usually don't fall asleep until 9:30pm/10ish and my schedule been like this for about 17 years 😬. I will try some of these techniques 🤞
This is incredible that we can get all this knowledge and wisdom for FREE, really grateful to both you! Would love to hear about relation of chamomile and sleep or quality of sleep to be exact. Again thanks for sharing all this and letting us sleep better
It’s been very helpful to absorbing the information that we are learning piece by piece in a series. I’ve been applying the knowledge each week. Currently sitting outside getting my morning sun drinking AG1 while I dive into this one, thanks!
1:52:23 So great to hear that even a cup of decaf still provides the antioxidants we need! I am weening off caffeine because I think it might be poking at my anxiety.
It's so fascinating to listen to Dr. Walker because he's so passionate about the subject of sleep! You can tell he's truly enthusiastic about his field of study, and I absolutely love seeing that. BTW, an episode about how different species sleep would be very interesting!
1. I'm a wellness coach and while I do have access to academic research, would love to hear Dr. Huberman's and Dr. Matt Walker's advice on the following 2. I need to get up earlier than my usual wakeup time, what is the optimal protocol for this, maybe using a consumer sleep tracker? 3. What is the effect of NSDR, Hatha Yoga, Weight Training, Meditation on sleep? 4. Due to social (raising a family) or work commitments (international shifts etc) if one cannot get the prescribed 7-9 hours of sleep but say 6, what's the next best way to fulfill the gap? (Any specific methods in pt 3 also) 5. How to stop bad dreams , waking up from nightmares, waking up with a sweat? 6. If one doesn't have access to natural sunlight in one's room, how effective is home automation of Air-conditioning and Artificial lighting? (Devices can be turned on or off, intensity varied based on time and or consumer sleep trackers) 7. How accurate are consumer sleep trackers? Mobile phones kept next to you measure sleep stages with gyroscopic movement, smart watches additionally add pulse rate calculation as well? 8. Methods to stop snoring apart from surgical interventions. 9. If weight training is only possible in evening suggest a protocol to reduce cortisol at the time of falling asleep. 10. If I'm exposed to bright artificial lights in the evening / night, as in a home recording studio an optimal protocol to go back to sleep? 11. If I slep less the previous day and I'm feeling drowsy during normal waking hours and am unable to work etc should I take a nap, should I take a stimulant like coffee to keep me up till my normal bedtime? 12. Protocols for naps / power naps? Especially wrt to duration / sleep cycles. A bed may not be available at this time. 13. Olfactory (smell) protocols for good sleep. Don't thank us for our interest in science, thank you for improving millions of lives!
I need tips on how to reverse my night shift schedule and become a daytime person again. For the past seven years, i have worked the night shift and then even when I had a year off during Covid, I was so used to being up at night, that became my normal. I would sleep during the day. I would wake up around 5\6 PM. That’s when I would get my grocery shopping done, exercise, avoid crowds and people. It was awesome. I can get a lot more done in a shorter amount of time because I was able to avoid people. But now I’m trying to switch careers and get a better paying job, but it requires going to work and being up during the day… I literally look like a drug addict. Like a zombie. The thought of working and trying to stay awake. during the day seems brutal to me . I don’t know how I’m going to function or stay awake at a new job. My doctor prescribed me, Lunesta, but I’m hesitant to start it because I don’t want to rely on pills to go to sleep and pills to wake up.
This is an excellent subject for anyone interested in sleep and naps, as it is engaging and comprehensive with profound insights. I thoroughly enjoy the Huberman podcast and have gained a wealth of knowledge from it. It is a must-watch.
Sleep is one of the vital aspects of human life. I have many clients who have always had issues in this area. Sleep, alongside being a physical matter, is often accompanied by psychological challenges in many cases. Thank you for your program; it had some new and helpful insights.
The whole SLEEP series has been enlightenng as the research continues I hope to learn more. Caffeine timing, when ingested, postponing it, limiting it based on sleep seems essential to our well being. But temperature needed to sleep and stay asleep has been the biggest eye opener for me. thank you.
A bunch of questions: 1. Are dreams mandatory part of REM sleep for baby in embryo, infant and an adult? 2. The reason I get this question is, as Matt said the babies in embryos do go through REM sleep, but how does that happen without any experiences with Parents or spacial memory or the world we live in? if Dream is a mandatory by-product/process in REM stage of sleep what does Dreaming in the babies in embryo look like? 3. In terms of brain activity or physiological changes like Lowered core Temperature, Lowered Heart Rate, Blood Pressure etc, how Is REM sleep different between baby in embryo, infant and an adult? Any genes/receptors that play a critical role here? Very informative series, kudos to Dr. Huberman and Dr. Matt Walker, Looking forward to the rest of the series :).
I grew up in Vietnam but moved to the US when I was a teenager. In Vietnam, around noon-ish, after lunch, everyone goes down for a nap, even the people working in offices. Most shops and businesses are closed down for naps. I told my mom that there's no such thing as naps for adults in the US, unless it's the weekend and you're extremely tired. She looks at me like I have 2 heads 😅
@10use Wherever they can. People get creative. Some fancy companies have cots under their desks. Some have a hammock in a supply closet. My sister brings a pillow and put her head on her desk.
Even dogs naped in the shade because the asphalt of the streets of Saigon melted under the noon sun. We children went home for lunch and returned to school at 2.
I live in the Balkans. My grandparents were farmers. They slept every afternoon and were very surprised to see me not taking a nap. It was a completely foreign concept for them to only sleep during the night.
Hello. Please address sleep apnea, OSA, and how this relationship with aging may decline in airway resistance, thus resulting in decreased/fragmented sleep at night. Can we infer that if one was to use PAP, despite the AASM protocol of AHI less than 5, that perhaps one would then receive deeper/N3 sleep compared to another who did not use PAP? I think PAP has much health benefits as we age - in a sense it is a form of Yoga breathing prior to entering N1, possibly decreasing sleep onset or treating insomnia. Thoughts? As male scientists, in their late 40’s, would you both try PAP as an experiment? What would your sleep architecture read? Would it be less fragmented? Would you need naps? I am assuming you do not use PAP….
Thank you for this whole series! I’m wondering if you could do an episode to talk about the importance of breathing in fresh air, have proper air circulation/ventilation in the room, and its effect on our brain function? I’m always curious on this topic because I know people who get headaches from not having enough air ventilation, but I feel like there aren’t enough studies online.
Hi Andrew and Matt, I got a question for you guys: I look well after my health and I got a nice routine for sleeping, I sleep for 7 hours and I fell “ready to go” when I wake up but I don’t have any dreams(never) I just blackout and wake up in the morning Is that a sign that I don’t reach too much REM stage or I simply just forget the dreams and if so is that a sign of something to worry ? I really enjoy each episode of this series, thank you for helping millions of us ❤
Recién descubro esta serie, me tentó a empezar desde el primer capitulo. Muy científico y excelentemente abordado. Muchas gracias. Saludos desde Buenos Aires
Thank you for this interesting series! I'm learning so much, it's really great! 😊 I have some "anecdata" on this first and second sleep thing: when I exert myself physically beyond my normal level, I fall asleep several hours earlier than usual, but wake up again after about 3-4 hours, feeling quite refreshed. Then, I stay awake for a few hours before getting sleepy again and falling back asleep. The next morning, I wake up at my usual time and feel no different than on any other morning. To me, that feels a lot like first and second sleep.
This episode sounds incredibly informative and timely, especially given the growing interest in sleep health and wellness. Understanding the science behind our sleep patterns and how to optimize them can truly transform our daily lives. Looking forward to tuning in and learning more! 💤
Im doing some yardwork for my aunt right now and told her I'm listening to a podcast about sleep. She is someone I consider a high level Doctor (she's given the commencement speech for Duke's medical school in the past if that gives any indication of her skills). First thing she says is "sleep is a superpower" 😂
This is such a great series. I'm hoping Dr. Matt will talk about the accuracy and efficacy of fitness trackers in regards to monitoting and improving sleep.
Thank you for another excellent podcast about improving sleep. There was a tidbit about autism and ADHD possibly messing up sleep cycles, can you please delve deeper into this and any tool protocols for us AuDHDers?
Great session! A few super interesting questions should have come up naturally but were skipped (I guess due to sticking with the program) - (1) How do we combat the loss of deep sleep quantity as we age? (2) How do we address the degradation as overall sleep quality (due to fragmentation) as we age? (3) Matt mentions that REM sleep should be 20% of overall sleep (and also mentions a number for deep sleep that declines with age) - If one is getting far less than those numbers (e.g., 5% REM vs. 20%), what can be done?
You both are making me into a sleep nerd. Last night, my sleep tracker showed 84% efficiency using the technique you described of staying awake longer. It's never been in the 80's. Over the next 3 weeks, I will improve quality before attempting quantity. I had been seeking more sleep the wrong way. Going to bed earlier. All that did was decrease efficiency towards 65%. Thanks you guys!! Rebooting my sleep habits is to improve a low IGG and immunity.❤
So far, it's working well. Although it's tough to have a later bed time, and no nap this week. The quality is increasing to 80% or above in the sleep monitor. How is yours going?
As a shift worker I have noticed when I sleep (durning the day) the nights I work I experience more REM sleep more then ever. I monitor my sleep and the quality of it too. I take naps when needed and have good day awake hours too. There is definitely a balance that you need to do with shift work
I wish there was recommendations about naps or how to improve sleep to mothers/caregivers with newborns/small children. So far they have not been mentioned once in this serie. Would love to see that group represented next time you sit down to chat! :-)
Hi Andrew, I train in the morning without coffee. Every morning, wake up , shower, hot water and lemon while I train to hydrate. After my training I have my latte with vegetable milk with coffee... the coffee with my Bialetti Coffee machine and Lavazza espresso like my granny taught me. Truly Italiano!!!
Another great segment with Dr Walker, I have been using your sleep cycle suggestions for awhile. I added your NSDR video before a video entitled Deep Sleep Hypnosis . It has improved my sleep greatly I had always heard how important our sleep was in general , but this series has explained the specific benefits. I do limit my caffeine and times , and it does help. I find the nap information so interesting, most likely for myself I will try the NSDR method . Looking forward to the last two episodes, thank you for sharing .
This series is a must listen! Have really enjoyed so far. Only half way through this episode but do hope there will be some discussions on parents who lose sleep in the infant timeframe of their children’s lives. (Or maybe I don’t want to hear that! 😂) Do day time naps help recoup? Is there anything biological built into birth mothers (due to hormonal changes) that helps mitigate the damages of lost sleep? If not this series, maybe in the future. Regardless, excellent content & thank you!
Great episode! I found the discussion about caffeine and its effects on sleep very insightful. I’m curious, does the consumption of green tea or pu-erh tea have the same impact on sleep as coffee? How do the caffeine levels in these teas compare, and are there any specific recommendations for timing their intake to avoid disrupting sleep? Thank you!
Andrew, I love you no matter what the negative people say about your personal life. They should all mine their business. You are amazing and I love everything you do to help everyone.❤
I did the caffeine nap, woke up with cold water, and immediately went out in the sun. Man oh man am I supercharged to play video games and eat Doritos.
Thank you very much for your series! Very helpful. Are you considering discussing the sleep pattern with the middle of the night awakenings and how to improve these?
Very interesting. I've noticed that even if all I can do is close my eyes and not fall asleep, I still get to a point of mental relief. I started timing it, and it's right around 18 minutes. I wonder how correlated that is to the short nap duration he was talking about. The closest thing I can relate it to is the feeling of switching over to primarily oxygen fuel (aerobic) around 15-20 minutes when you're jogging.

Brilliant episode. I have two questions regarding caffeine. Since it is blocking adenosine receptors and thereby inhibiting adenosine clearance(sleep), I would expect daily caffeine consumption to lead to chronically elevated adenosine levels. First question, is the above the case? I saw some study had shown this in mice. Second question; what do we know about other effects of adenosine? Even if the "sleepiness" aspect is completely cancelled out by the caffeine I suppose it may impact other things in the body.
I sleep once every two nights (~40 hours awake, ~8 hours sleep). What would this type of sleep schedule be called? The reason I maintain this schedule is that I find it easier to get work done at night when there are no distractions. While this schedule has been productive so far (I'm doing a PhD), I'm worried that it will eventually turn me into a psychotic maniac. Can anyone relate to a schedule like this? By the way, I have greatly enjoyed this guest series so far. Very fascinating!
I can relate. I followed a similar sort of pattern while studying a lot and I enjoyed being a night owl. I handled very little sleep remarkably well. The quietness of the night made me extremely productive and I accomplished a lot in a shorter time frame. This didn’t last for long however, and I had years and years of many sleep related difficulties following that time. I function well on little or no sleep, But I don’t want to be that way, and I wouldn’t like to go back to a time like that.
Professor Matt Walker mentioned that one could take certain tests to test his/her sensitivity to caffeine. It'd be helpful if a link to a website where one can find such tests was included in the description box.
I hope I’m not missing this elsewhere in the comments, but I would like to know when my teenager should sleep. Should we let her sleep in the weekends? Also, Dr. Walker said there is a great book on first sleep and second sleep, but he doesn’t mention the title. Could he share it, please? Thanks for the podcast-it’s like getting to take classes without going to school. If biology had been this interesting when I was in school I’d have done a lot better in it.
Also waiting for caffeine until well after waking up is such a good thing I did it the first two times after being off caffeine and stimulants for a month and a half and it was incredible waking up not feeling like a truck slammed into you or like you know, butpretty immediately a couple days into it you wake up and you just your body wants to get with it and you do that caffeine earlier and then a couple days don’t understand
Unfortunately the cocktail from momentous sleep bundle hasn’t worked for me. It’s been 2 weeks. Should I stop or stick it out ? There’s definitely some sleep hygiene I learned from this series should help regardless. I appreciate you 👊🏽👊🏽👍🏽👍🏽💪🏽💪🏽
Great breakdown of how naps can be beneficial for some people. Also thanks for the follow up on delaying coffee after waking up. I tried it and had no benefits and felt it only sacrificed an enjoyable way to start the day.
you should do a video on self control, where you talk about tools such as timed locks. I learned of timed lock from your podcast when you barely mentioned it, but it is saving my life
@@kssgpv nah, failure in many ways and he knows it. someone like bryan johnson would be an expert of self control, but who has 500 mil to spend on self control?:)
It was definitely interesting to learn about caffeine's connection to adenosine receptors because half the time drinking coffee makes me even more sleepy.
I can attest to polyphasic sleep not working. I tried the uberman schedule for a month back in 2005. I was exhausted all the time. I was especially useless around 4am. I ended up getting sick and fired from my job. I loved the idea of it at the time but now would strongly advise against it unless it's for something short term where being awake as much as possible is more important than health. As I understand it, it was first studied as an option for solo round the world sailors. It might make more sense for something like that.
Also say you have depression and a narcolepsy or any of these things or ADD you’re taking stimulants with which make it even harder for you to sleep. It’s like it’s really crazy and overwhelming.
Would love to see an episode on donating blood / plasma / platelets and the effect it has on the body. Especially relating to people who perform regular exercise.
Loving these episodes! I'm curious about sleep quality of people in blue zones. Also, that Bryan Johnson fellow says he has perfect sleep. What does he do and is it realistic?
Dr. Huberman, Many people often find themselves in dilemma when sleeping a littel later than their usual timing is the sacrifice of one thing out of completing sleep cycle and wake up at usual timing. What does data suggest?
Regarding the decline in deep sleep as we age, I'd like to speculate that the average persons ability or motivation to engage in new persuits and experiences declines with age. You have to put more and more effort in to overcome the brains tendancy to take the lazy option. But for some people the stimulation of continuous learning is habitual. And I wonder if those individuals migth experience more deep sleep than average because it is required for consolidation of memory and the physical plasticity process of rewiring the neural connections?
Thank you Prof. Huberman for such a remarkable journey of enriched learning thru you and your incredible guests. Is there a possibility that children with Autism and/or ADHD have a different sleep cycle, or the chemical release during sleep cycles is different compared to children who do not have Autism or ADHD? Thank you, for your insight.
What a treat hearing you both! An amazing episode! I would love an episode about sleeping throughout the animal kingdom! I am reading An immense world, as suggested by Dr. Lisa Feldman Barrett. Wonderful!
Thanks to this series, I’ve become an expert at sleep! I can do it with my eyes closed.
Lol! I see what you did there
😂😂😂
😂
But can you do it lying down too?
and they see women dont make good jokes ... that was briliant
Can I just comment on how fantastic it is to have not only the knowledge but also the rich vocabulary that goes with this talk, its truly very engaging
I'm especially lucky to have it considering I've been diagnosed with insomnia last week and my sleep has been getting better everyday
I could listen to Matt Walker talk all day long, which is quite handy with this long form structure. It’s great seeing him so accomplished considering he grew up 15 minutes away from me.
Dr Walker’s fabulous voice could easily put one to sleep, he needs to be a voice on a meditation or sleep app ❤ this has all been SO very helpful.
Very true
I agree
Yes!
Andrew, for you, really impressed at the effort you are making to listen quietly and let your guest speak.
Really appreciate this episode, Mathew finally addressed the issue with elderly and insomnia community. It’s the best and the most clear explanation of sleep deprivation & insomnia episodes ever. Thank you Andrew for doing this podcast.
Great to see university professors telling the public about advances in science, and focusing on public outreach and engagement. 👍
Public engagement with research is a two-way process with the goal of generating mutual benefit between the public and researchers and ultimately enhancing the quality or impact of research.
"these tools that NASA and that laboratories have developed, ... they translate into kind of a broader significance..." (01.14.30)
Matt’s voice is all I need to fall asleep. I even avoid listening to his wonderful explanations while having my morning coffee. His voice is so comforting.
I have been watching Huberman series for almost 5 hours now! Come on, how one man can bring worldwide scientists to impart this barrel of knowledge. I love your aura with Dr. Matt Walker! Love the duo here! My favourite till date, Dr, Huberman.
Being able to work from home I can sleep from 10:30 pm to 6:30 am and from 1:30 to 2:00pm almost daily. This has improved my life so much (concentration, energy, productivity, skin quality)
Throughout this guest series it is clear that temperature and temperature regulation have profound importance for our physiology. This is certainly the first time i've heard it come up again and again. Maybe a podcast on thermoregulation and/or dysregulation would be good.
¹Q
Great suggestion. I would love to hear a podcast (by Dr Huberman, of course) all about thermoregulation, especially the limits of human thermoregulation, and what happens to the body in uncompensable heat stress (e.g., development of exertional heat illnesses).
I literally can't fall asleep well unless I take a hot shower first. Even if it's a really quick shower.
9:17 9:27 9:29
@@Lili-xq9snyour body will lower your body temperature after the hot shower and therefore sleep better since you need your body temperature to drop in order to sleep.
Your podcast, literally change my life, some podcast that are 3-2 hours long, I watched them multiple times. Your explanation is very clear sir. I always amaze to every podcast I hear. It feels like you accompany me walking. I listen to them while taking my walk outside. You provide all the information for me, so I don’t really need to waste more time, looking them out myself. THANK YOU
Need a podcast about overnight shift workers best protocol to be as healthy as possible workout routine nutrition how to stay awake and alert through the shift etc
Yes
I'm pretty sure that's going to be part of this series. The bottom line is though, that it will be about minimizing damage. You cannot avoid that fact that there is nothing you can do that will change the fact that shift work wrecks havoc on the body.
Huberman had an episode on that!
He has an episode on that. Google it with some of the terms you used in your question
Yes! I work 2am-11am
06:14 🛌 Different types of sleep exist across the lifespan, from highly polyphasic in infancy to more monophasic in adulthood.
16:46 🧠 REM sleep plays a crucial role in brain development, particularly in stimulating the growth of connections within the brain during infancy.
19:47 🔄 Sleep patterns stabilize around age five or six, with a consistent ratio of about 20% REM sleep to 80% non-REM sleep throughout adulthood.
22:04 🌞 Traditional societies and cultures may have different sleep patterns, including siesta-like naps and waking patterns determined by temperature rather than sunrise.
23:24 🌙 Sleep schedules vary based on chronotypes, with some people naturally inclined to sleep and wake earlier, while others prefer later sleep times.
25:13 🔄 Variability in sleep preferences across individuals reduces collective vulnerability, ensuring someone is always awake to monitor the environment.
29:11 🧬 Chronotypes, while influenced by genetics, can be modified by life circumstances and exposure to light.
33:00 ⏰ Biphasic sleep patterns include siesta-like naps and segmented sleep, with historical examples of first sleep and second sleep.
39:29 🛌 Body position affects sleepiness, with lying down facilitating thermal dissipation and core body temperature drop, promoting sleep onset.
42:02 📚 Napping can enhance learning and memory consolidation, with benefits observed in emotional regulation and cognitive function.
46:02 💤 Naps improve attention, focus, decision-making, and mood, but may reduce sleep pressure, potentially affecting nighttime sleep.
47:11 💤 Napping can release built-up sleepiness, but it's advised against for those with insomnia as it may hinder nighttime sleep quality.
48:46 🕒 Napping late in the day can reduce sleepiness before bedtime, akin to snacking before a meal, so it's recommended to avoid napping too close to bedtime.
53:20 🕑 Optimal nap duration for most people aiming for a quick reboot and improved alertness is around 20 minutes, as it provides benefits without causing sleep inertia or grogginess.
56:32 🌙 Longer naps offer more benefits, but they come with the tradeoff of potential sleep inertia, where one may feel worse initially upon waking.
57:27 🚫 Avoid napping too late in the day, generally recommended not to nap after 3:00 p.m., to prevent interference with nighttime sleep.
01:00:54 🤔 Napping isn't necessary for everyone, but if interested, mimicking nighttime conditions can increase the likelihood of a successful nap, focusing on factors like darkness, quiet, and comfort.
01:04:04 💭 Exploring alternative states of consciousness, like meditative or "linal" states, could offer benefits similar to napping, potentially involving local deep sleep in the brain.
01:08:23 🚀 NASA's research on napping showed significant boosts in alertness and productivity, leading to the adoption of "power naps" to enhance performance, particularly in astronauts and pilots.
01:10:49 🛫 Prophylactic napping, or "power naps," was a term coined for optimal nap placement during long-haul flights, suggesting early napping sustains alertness throughout the flight.
01:13:35 🧘♂ Yoga Nidra, or "yoga sleep," offers mental and physical restoration through relaxation, but misconceptions exist. "Non-sleep deep rest" protocols maintain Yoga Nidra benefits without mystical elements.
01:15:46 🌙 Late-day naps can disrupt nighttime sleep, leading to fragmented sleep and difficulty falling back asleep after waking during the night.
01:19:23 ⏰ Insomnia sufferers are advised to avoid napping, as it can exacerbate nighttime sleep struggles, worsening sleep quality and perpetuating sleeplessness.
01:21:53 🛌 Older adults' daytime napping habits can reflect poor nighttime sleep quality, potentially indicating health risks and higher mortality rates rather than being a direct cause.
01:29:24 ☕ Caffeine functions as an adenosine antagonist, blocking adenosine receptors in the brain to mitigate sleepiness temporarily, explaining the concept of a "caffeine nap" or "nappuccino."
01:32:39 ☕ Caffeine's initial boost after consumption within the first few minutes is not due to its effects but rather the temperature of the drink, usually warm, which contributes to an immediate sensation of alertness.
01:35:51 🕒 Structuring naps strategically around caffeine intake can mitigate sleep inertia, creating what's known as a "caffeine nap" or "nappuccino." Consuming caffeine just before a nap allows its effects to coincide with waking up, providing a dual benefit.
01:41:24 💤 Adenosine clearance primarily occurs during deep non-REM sleep when the brain is less metabolically active. Other activities like exercise or exposure to light may not directly affect adenosine levels but can promote alertness through different mechanisms.
01:43:26 🌅 Delaying caffeine intake by 90 to 120 minutes after waking can help offset the afternoon crash and potentially improve sleep quality by avoiding interference with adenosine clearance and allowing for a clearer assessment of sleep restoration upon waking.
01:55:00 ☕ Caffeine and alcohol use can form a cycle of dependency affecting sleep, with caffeine as an upper in the morning and alcohol as a downer at night.
01:55:37 💤 Moderate caffeine intake by not exceeding three cups of coffee per day and being mindful of sensitivity, adjusting timing accordingly.
01:57:03 🛌 Various nap types, including caffeine naps, offer benefits, with additional potential from combinations like nap plus cold face washing or bright light exposure.
02:01:50 🔄 Polyphasic sleep, popularized by biohacking, involves splitting sleep into multiple phases within a 24-hour period but lacks scientific support for health benefits and may have negative consequences.
02:09:53 ⚠ Polyphasic sleep schedules, historically traced to 1943, pose risks including decreased total sleep, poor sleep quality, reduced REM sleep, and impaired cognition and health, with potential safety concerns like increased risk of accidents.
thank you
Thank you
absolute legend, thank you
Yes, I found the 16:46 timestamp interesting too. My daughter was born with reflux and basically didn't sleep for the first year/ year and a half of her life. She was later diagnosed with ADHD and I often wonder if that inability to sleep (because of the pain she was in) had something to do with it. It would be an interesting study to look at ADHD and reflux in infancy.
Thank you! You're helping the world be a better place
This podcast is not just rich with knowledge but also a masterclass in communication. Very complex knowledge, beautifully delivered!
I used to sleep over a lunch break at work for like 20min. Omg it would boost me to finish my work.
We need a segment on menopause and sleeping. Thanks!
Yes god please!!!,
Thank you for hosting this wonderful podcast. I have listened to everything on this sleep series. Dr. Matt reiterates the importance of QQRT, I want to know if regularity and timing is as important when the body has the flu, is injured, or ailing in some way? I always feel inclined to sleep as much as possible when I am injured or unwell. Thanks again, and keep up the great work!
😂Thank you both again!! I listened to all the information and suggestions earlier yesterday morning, and have been implementing them (the cold water vs warm water on face and palms was a huge help too, because others in the same field have been telling me to splash cold water on my face all the time, not explaining the timing differences that Dr. Walker explained so thoroughly, and it helps me understand why I was wide awake after splashing the wrong temperature of water on my face at night and couldn't sleep, you have no idea how much you and your team and explanations are appreciated!!) Both of you and your teams are all amazing!!❤❤
I slept from 10pm to 5 am, only awakening once at 3am; fell right back to sleep. yay!!!
As someone struggling with sleep, especially during pregnancy and with small kids waking you during the night, it would be very interesting with an episode focusing on pregnancy/parenting sleep.
It would also be very interesting with an episode focusing on sleep in psychiatric conditions (ADHD, autism etc.), which at least to me appears to be an unrecognized topic (i.e., sleep issues in these conditions).
In Spain, many people still take siestas in the summer when it's really hot, and work schedules switch from split shifts to continuous ones. For the rest of the year, the siesta is replaced by coffee and 2 hours of unproductive work.
I love you both and appreciate how generous you are to share your knowledge with us. I'll put this series in my list of "must listen". thank you, from San Diego
Man I'm loving this series
I wake up every day at 4am and try to take a 20-minute nap around 2pm. The data aligns!!!! Thank you for all the help 🙏
Dr. Huberman,
I greatly appreciate your work on neuroscience and sleep. Given your expertise, I’m seeking advice on managing sleep for firemen who often have challenging schedules. We typically work 24 hours on, followed by 24 hours off, repeating this cycle twice, and then taking either four or six days off. This schedule can make maintaining a regular sleep pattern difficult.
Could you provide insights or recommendations on how to best manage and optimize sleep under such conditions? Specifically, are there any strategies for adapting our circadian rhythm or managing sleep debt effectively during our working days and recovery days?
Your job is incredibly risky for so many reasons. You will need to spend your life off work trying to minimize all of the health risks. Once you understand that your job is really dangerous for you even when not at a fire, your life changes. Blackout curtains, strict routines, including diet and hydration, mental health strategies, etc. It will be very difficult to spend time with people who aren't living that schedule.
He’s not going to answer
Do you mean firefighters?
What a fantastic series; thank you both for pulling it together!
I was surprised however that significant timezone shifting wasn’t really discussed in any of the 6 episodes. For those vacationing, or required by work, in locations between 6 and 18 hrs off of their home timezone, it would be interesting to hear what best practices might be for powering through a trip, adapting as quickly as possible to the new timezone, caffeine use for both short and longer-term visits, and importantly, decision making when jet-lagged in more significant offsets.
How is decision making/learning impacted when shifting to a timezone 10 hrs off of your usual, and then back again?
Thanks!
You make my life so easier. Can not thank you enough. Plus the process of delivery of knowledge by both of you is a real joy for eyes and ears, and brain. You are stalwarts of truth and generosity. Bravo! Щиро дякую! Слава Україні!
Thank you for this series. I leave for work at 3am and start my work day at 4am. I've always had a hard time sleeping and usually don't fall asleep until 9:30pm/10ish and my schedule been like this for about 17 years 😬. I will try some of these techniques 🤞
This is incredible that we can get all this knowledge and wisdom for FREE, really grateful to both you! Would love to hear about relation of chamomile and sleep or quality of sleep to be exact. Again thanks for sharing all this and letting us sleep better
It’s been very helpful to absorbing the information that we are learning piece by piece in a series. I’ve been applying the knowledge each week. Currently sitting outside getting my morning sun drinking AG1 while I dive into this one, thanks!
You might also wanna listen to Kristen Holmes from Whoop on Diary of a CEO podcast. I learnt as much from her too
@@banerjeehome5913thank you! I’ll check it out.
1:52:23 So great to hear that even a cup of decaf still provides the antioxidants we need! I am weening off caffeine because I think it might be poking at my anxiety.
It's so fascinating to listen to Dr. Walker because he's so passionate about the subject of sleep! You can tell he's truly enthusiastic about his field of study, and I absolutely love seeing that. BTW, an episode about how different species sleep would be very interesting!
I really appreciate having all this current valuable thinking on sleep in one place. Thank you!
1. I'm a wellness coach and while I do have access to academic research, would love to hear Dr. Huberman's and Dr. Matt Walker's advice on the following
2. I need to get up earlier than my usual wakeup time, what is the optimal protocol for this, maybe using a consumer sleep tracker?
3. What is the effect of NSDR, Hatha Yoga, Weight Training, Meditation on sleep?
4. Due to social (raising a family) or work commitments (international shifts etc) if one cannot get the prescribed 7-9 hours of sleep but say 6, what's the next best way to fulfill the gap? (Any specific methods in pt 3 also)
5. How to stop bad dreams , waking up from nightmares, waking up with a sweat?
6. If one doesn't have access to natural sunlight in one's room, how effective is home automation of Air-conditioning and Artificial lighting? (Devices can be turned on or off, intensity varied based on time and or consumer sleep trackers)
7. How accurate are consumer sleep trackers? Mobile phones kept next to you measure sleep stages with gyroscopic movement, smart watches additionally add pulse rate calculation as well?
8. Methods to stop snoring apart from surgical interventions.
9. If weight training is only possible in evening suggest a protocol to reduce cortisol at the time of falling asleep.
10. If I'm exposed to bright artificial lights in the evening / night, as in a home recording studio an optimal protocol to go back to sleep?
11. If I slep less the previous day and I'm feeling drowsy during normal waking hours and am unable to work etc should I take a nap, should I take a stimulant like coffee to keep me up till my normal bedtime?
12. Protocols for naps / power naps? Especially wrt to duration / sleep cycles. A bed may not be available at this time.
13. Olfactory (smell) protocols for good sleep.
Don't thank us for our interest in science, thank you for improving millions of lives!
Great questions.
I need tips on how to reverse my night shift schedule and become a daytime person again. For the past seven years, i have worked the night shift and then even when I had a year off during Covid, I was so used to being up at night, that became my normal. I would sleep during the day. I would wake up around 5\6 PM. That’s when I would get my grocery shopping done, exercise, avoid crowds and people. It was awesome. I can get a lot more done in a shorter amount of time because I was able to avoid people. But now I’m trying to switch careers and get a better paying job, but it requires going to work and being up during the day… I literally look like a drug addict. Like a zombie. The thought of working and trying to stay awake. during the day seems brutal to me .
I don’t know how I’m going to function or stay awake at a new job. My doctor prescribed me, Lunesta, but I’m hesitant to start it because I don’t want to rely on pills to go to sleep and pills to wake up.
This is an excellent subject for anyone interested in sleep and naps, as it is engaging and comprehensive with profound insights. I thoroughly enjoy the Huberman podcast and have gained a wealth of knowledge from it. It is a must-watch.
Sleep is one of the vital aspects of human life. I have many clients who have always had issues in this area. Sleep, alongside being a physical matter, is often accompanied by psychological challenges in many cases. Thank you for your program; it had some new and helpful insights.
The best host with the best guest 👏👏👏
I’ve been loving your show since the beginning and this series is so freaking awesome. Andrew, Thanks for just being you & God Bless You My Friend.
The whole SLEEP series has been enlightenng as the research continues I hope to learn more. Caffeine timing, when ingested, postponing it, limiting it based on sleep seems essential to our well being. But temperature needed to sleep and stay asleep has been the biggest eye opener for me. thank you.
Matt Walker is so cheerful and enthusiastic, its infectious
"I'm excited every time for the new episodes of you two, like when I was a little kid waiting for Dragonball on TV."
A bunch of questions:
1. Are dreams mandatory part of REM sleep for baby in embryo, infant and an adult?
2. The reason I get this question is, as Matt said the babies in embryos do go through REM sleep, but how does that happen without any experiences with Parents or spacial memory or the world we live in? if Dream is a mandatory by-product/process in REM stage of sleep what does Dreaming in the babies in embryo look like?
3. In terms of brain activity or physiological changes like Lowered core Temperature, Lowered Heart Rate, Blood Pressure etc, how Is REM sleep different between baby in embryo, infant and an adult? Any genes/receptors that play a critical role here?
Very informative series, kudos to Dr. Huberman and Dr. Matt Walker, Looking forward to the rest of the series :).
I grew up in Vietnam but moved to the US when I was a teenager. In Vietnam, around noon-ish, after lunch, everyone goes down for a nap, even the people working in offices. Most shops and businesses are closed down for naps.
I told my mom that there's no such thing as naps for adults in the US, unless it's the weekend and you're extremely tired. She looks at me like I have 2 heads 😅
Where do people sleep while at work.
@10use Wherever they can. People get creative. Some fancy companies have cots under their desks. Some have a hammock in a supply closet. My sister brings a pillow and put her head on her desk.
Even dogs naped in the shade because the asphalt of the streets of Saigon melted under the noon sun. We children went home for lunch and returned to school at 2.
I live in the Balkans. My grandparents were farmers. They slept every afternoon and were very surprised to see me not taking a nap. It was a completely foreign concept for them to only sleep during the night.
Hello. Please address sleep apnea, OSA, and how this relationship with aging may decline in airway resistance, thus resulting in decreased/fragmented sleep at night. Can we infer that if one was to use PAP, despite the AASM protocol of AHI less than 5, that perhaps one would then receive deeper/N3 sleep compared to another who did not use PAP? I think PAP has much health benefits as we age - in a sense it is a form of Yoga breathing prior to entering N1, possibly decreasing sleep onset or treating insomnia. Thoughts? As male scientists, in their late 40’s, would you both try PAP as an experiment? What would your sleep architecture read? Would it be less fragmented? Would you need naps? I am assuming you do not use PAP….
Thank you for this whole series! I’m wondering if you could do an episode to talk about the importance of breathing in fresh air, have proper air circulation/ventilation in the room, and its effect on our brain function? I’m always curious on this topic because I know people who get headaches from not having enough air ventilation, but I feel like there aren’t enough studies online.
Hi Andrew and Matt,
I got a question for you guys:
I look well after my health and I got a nice routine for sleeping, I sleep for 7 hours and I fell “ready to go” when I wake up but I don’t have any dreams(never) I just blackout and wake up in the morning
Is that a sign that I don’t reach too much REM stage or I simply just forget the dreams and if so is that a sign of something to worry ?
I really enjoy each episode of this series, thank you for helping millions of us ❤
Recién descubro esta serie, me tentó a empezar desde el primer capitulo. Muy científico y excelentemente abordado. Muchas gracias. Saludos desde Buenos Aires
Thank you for this interesting series! I'm learning so much, it's really great! 😊 I have some "anecdata" on this first and second sleep thing: when I exert myself physically beyond my normal level, I fall asleep several hours earlier than usual, but wake up again after about 3-4 hours, feeling quite refreshed. Then, I stay awake for a few hours before getting sleepy again and falling back asleep. The next morning, I wake up at my usual time and feel no different than on any other morning. To me, that feels a lot like first and second sleep.
Very helpful. In single mothers , full time student& work and trying to figure it out comfortably
This episode sounds incredibly informative and timely, especially given the growing interest in sleep health and wellness. Understanding the science behind our sleep patterns and how to optimize them can truly transform our daily lives. Looking forward to tuning in and learning more! 💤
Im doing some yardwork for my aunt right now and told her I'm listening to a podcast about sleep. She is someone I consider a high level Doctor (she's given the commencement speech for Duke's medical school in the past if that gives any indication of her skills). First thing she says is "sleep is a superpower" 😂
This is such a great series. I'm hoping Dr. Matt will talk about the accuracy and efficacy of fitness trackers in regards to monitoting and improving sleep.
Thank you for another excellent podcast about improving sleep. There was a tidbit about autism and ADHD possibly messing up sleep cycles, can you please delve deeper into this and any tool protocols for us AuDHDers?
Yes also REM disruptive sleep disorder, RLS (restless leg), and night terrors… fading in and out of sleep paralysis
Great session! A few super interesting questions should have come up naturally but were skipped (I guess due to sticking with the program) - (1) How do we combat the loss of deep sleep quantity as we age? (2) How do we address the degradation as overall sleep quality (due to fragmentation) as we age? (3) Matt mentions that REM sleep should be 20% of overall sleep (and also mentions a number for deep sleep that declines with age) - If one is getting far less than those numbers (e.g., 5% REM vs. 20%), what can be done?
Matt Walker’s elfish new look is a better Elrond than Amazon’s Prime Elrond!
😊😊😊😊
Funny cos I've heard him make two LotR references in the episodes so far. Clearly a fan 🧝♀️
You guys are not nice…
@@evagalstian244it's just a little bit of fun, I'm sure Matt wouldn't feel insulted. :)
You both are making me into a sleep nerd. Last night, my sleep tracker showed 84% efficiency using the technique you described of staying awake longer. It's never been in the 80's. Over the next 3 weeks, I will improve quality before attempting quantity. I had been seeking more sleep the wrong way. Going to bed earlier. All that did was decrease efficiency towards 65%.
Thanks you guys!! Rebooting my sleep habits is to improve a low IGG and immunity.❤
I am trying the same thing! Hope it works 🤞🏻
So far, it's working well. Although it's tough to have a later bed time, and no nap this week. The quality is increasing to 80% or above in the sleep monitor.
How is yours going?
As a shift worker I have noticed when I sleep (durning the day) the nights I work I experience more REM sleep more then ever. I monitor my sleep and the quality of it too. I take naps when needed and have good day awake hours too. There is definitely a balance that you need to do with shift work
I wish there was recommendations about naps or how to improve sleep to mothers/caregivers with newborns/small children. So far they have not been mentioned once in this serie. Would love to see that group represented next time you sit down to chat! :-)
Hi Andrew, I train in the morning without coffee. Every morning, wake up , shower, hot water and lemon while I train to hydrate. After my training I have my latte with vegetable milk with coffee... the coffee with my Bialetti Coffee machine and Lavazza espresso like my granny taught me. Truly Italiano!!!
Why hot water with a lemon?
@@Cheximus It is an effective way to stimulate the metabolism and keep the body hydrated
Thanks
Another great segment with Dr Walker, I have been using your sleep cycle suggestions for awhile. I added your NSDR video before a video entitled Deep Sleep Hypnosis . It has improved my sleep greatly I had always heard how important our sleep was in general , but this series has explained the specific benefits.
I do limit my caffeine and times , and it does help. I find the nap information so interesting, most likely for myself I will try the NSDR method . Looking forward to the last two episodes, thank you for sharing .
This series is a must listen! Have really enjoyed so far. Only half way through this episode but do hope there will be some discussions on parents who lose sleep in the infant timeframe of their children’s lives. (Or maybe I don’t want to hear that! 😂) Do day time naps help recoup? Is there anything biological built into birth mothers (due to hormonal changes) that helps mitigate the damages of lost sleep? If not this series, maybe in the future. Regardless, excellent content & thank you!
Great episode! I found the discussion about caffeine and its effects on sleep very insightful. I’m curious, does the consumption of green tea or pu-erh tea have the same impact on sleep as coffee? How do the caffeine levels in these teas compare, and are there any specific recommendations for timing their intake to avoid disrupting sleep? Thank you!
Andrew, I love you no matter what the negative people say about your personal life. They should all mine their business. You are amazing and I love everything you do to help everyone.❤
Why bring it up?
What are you referring to?
He's not.good person, a good person doesn't cheat and lie
I did the caffeine nap, woke up with cold water, and immediately went out in the sun. Man oh man am I supercharged to play video games and eat Doritos.
Thank you very much for your series! Very helpful. Are you considering discussing the sleep pattern with the middle of the night awakenings and how to improve these?
¡Hola Profe!As a "novice napper",I thank You.Definitely going to try "cold face,cold hands method".Thank You for Your hard work and care for all us.
Dr Huberman I’ve listened to everything you have said about fibromyalgia, so far. Do you think you will ever have a podcast more dedicated to it?
Very interesting. I've noticed that even if all I can do is close my eyes and not fall asleep, I still get to a point of mental relief. I started timing it, and it's right around 18 minutes. I wonder how correlated that is to the short nap duration he was talking about. The closest thing I can relate it to is the feeling of switching over to primarily oxygen fuel (aerobic) around 15-20 minutes when you're jogging.

Thank you Andrew your service to us is invaluable.
Can’t agree more!
Brilliant episode.
I have two questions regarding caffeine. Since it is blocking adenosine receptors and thereby inhibiting adenosine clearance(sleep), I would expect daily caffeine consumption to lead to chronically elevated adenosine levels. First question, is the above the case? I saw some study had shown this in mice.
Second question; what do we know about other effects of adenosine? Even if the "sleepiness" aspect is completely cancelled out by the caffeine I suppose it may impact other things in the body.
Dr. Matt Surfer in da lab 🌊😎
first thought
He's a surfer? He's so smart! Must be all the water and sunshine.
I sleep once every two nights (~40 hours awake, ~8 hours sleep). What would this type of sleep schedule be called? The reason I maintain this schedule is that I find it easier to get work done at night when there are no distractions. While this schedule has been productive so far (I'm doing a PhD), I'm worried that it will eventually turn me into a psychotic maniac. Can anyone relate to a schedule like this? By the way, I have greatly enjoyed this guest series so far. Very fascinating!
You are risking your sanity.
Plenty of research in how to use this in torture.
I can relate. I followed a similar sort of pattern while studying a lot and I enjoyed being a night owl. I handled very little sleep remarkably well. The quietness of the night made me extremely productive and I accomplished a lot in a shorter time frame. This didn’t last for long however, and I had years and years of many sleep related difficulties following that time. I function well on little or no sleep, But I don’t want to be that way, and I wouldn’t like to go back to a time like that.

Unhealthy!
Professor Matt Walker mentioned that one could take certain tests to test his/her sensitivity to caffeine. It'd be helpful if a link to a website where one can find such tests was included in the description box.
It's one of the best series on sleep. Please keep them coming 💪😴
@Andrew what about the loonar effects on sleep? Thank you for your amazing podcast 🙏❤
I hope I’m not missing this elsewhere in the comments, but I would like to know when my teenager should sleep. Should we let her sleep in the weekends? Also, Dr. Walker said there is a great book on first sleep and second sleep, but he doesn’t mention the title. Could he share it, please? Thanks for the podcast-it’s like getting to take classes without going to school. If biology had been this interesting when I was in school I’d have done a lot better in it.
Thank you two heroes brothers ❤
Also waiting for caffeine until well after waking up is such a good thing I did it the first two times after being off caffeine and stimulants for a month and a half and it was incredible waking up not feeling like a truck slammed into you or like you know, butpretty immediately a couple days into it you wake up and you just your body wants to get with it and you do that caffeine earlier and then a couple days don’t understand
Unfortunately the cocktail from momentous sleep bundle hasn’t worked for me. It’s been 2 weeks. Should I stop or stick it out ?
There’s definitely some sleep hygiene I learned from this series should help regardless. I appreciate you 👊🏽👊🏽👍🏽👍🏽💪🏽💪🏽
Literally made me fall asleep listening to this 😴
Loving this series! Thank you guys 😊
Great breakdown of how naps can be beneficial for some people.
Also thanks for the follow up on delaying coffee after waking up.
I tried it and had no benefits and felt it only sacrificed an enjoyable way to start the day.
I love how legitimately excited Matt became when he was discussing nap-stacking 😂
you should do a video on self control, where you talk about tools such as timed locks. I learned of timed lock from your podcast when you barely mentioned it, but it is saving my life
he's an expert of self control🤣 men..
@@kssgpv nah, failure in many ways and he knows it. someone like bryan johnson would be an expert of self control, but who has 500 mil to spend on self control?:)
❤ loved this!
Amazingly helpful information.
Thanks to both of you🥰
It was definitely interesting to learn about caffeine's connection to adenosine receptors because half the time drinking coffee makes me even more sleepy.
I can attest to polyphasic sleep not working. I tried the uberman schedule for a month back in 2005. I was exhausted all the time. I was especially useless around 4am. I ended up getting sick and fired from my job. I loved the idea of it at the time but now would strongly advise against it unless it's for something short term where being awake as much as possible is more important than health. As I understand it, it was first studied as an option for solo round the world sailors. It might make more sense for something like that.
I just watched the wwhole podcast, I LOVE this guest and I didnt know he had a podcast so I might go check it up
I ALSO JUST FOUND OUT HE IS THE WRITTER OF "WHY WE SLEEP"
Also say you have depression and a narcolepsy or any of these things or ADD you’re taking stimulants with which make it even harder for you to sleep. It’s like it’s really crazy and overwhelming.
One of the best... THanks!
Would love to see an episode on donating blood / plasma / platelets and the effect it has on the body. Especially relating to people who perform regular exercise.
It would be great if we could get a 6 part deep dive on the other pillars of health: nutrient dense eating and exercise ❤
Loving these episodes! I'm curious about sleep quality of people in blue zones. Also, that Bryan Johnson fellow says he has perfect sleep. What does he do and is it realistic?
Dr. Huberman,
Many people often find themselves in dilemma when sleeping a littel later than their usual timing is the sacrifice of one thing out of completing sleep cycle and wake up at usual timing.
What does data suggest?
Regarding the decline in deep sleep as we age, I'd like to speculate that the average persons ability or motivation to engage in new persuits and experiences declines with age. You have to put more and more effort in to overcome the brains tendancy to take the lazy option. But for some people the stimulation of continuous learning is habitual. And I wonder if those individuals migth experience more deep sleep than average because it is required for consolidation of memory and the physical plasticity process of rewiring the neural connections?
Fantastic series, thank you both!
I’m curious whether there is any negative impact of occasional napping for thise who cannot nap daily.
Thank you Prof. Huberman for such a remarkable journey of enriched learning thru you and your incredible guests. Is there a possibility that children with Autism and/or ADHD have a different sleep cycle, or the chemical release during sleep cycles is different compared to children who do not have Autism or ADHD? Thank you, for your insight.
What a treat hearing you both! An amazing episode! I would love an episode about sleeping throughout the animal kingdom! I am reading An immense world, as suggested by Dr. Lisa Feldman Barrett. Wonderful!
