The average person experiences dozens of individual itches each day. We’ve all experienced the annoyance of an inconvenient itch - but have you ever pondered why we itch in the first place? Is there actually an evolutionary purpose to the itch, or is it simply there to annoy us? Emma Bryce digs deep into the skin to find out.
Lesson by Emma Bryce, animation by Sashko Danylenko.
My whole body throughout this whole video: *guess I'll itch*
Even talking about itching can make you itch.

SAME.
I can’t hold it for long ahhhhhh
Same....
When your nose itches but you are in barber shop
Agreed, that is the worst normal itch you can get.
Omg yes
Or your ears
AAAAAHHHHHHHHHHHHH
Yep that’s the worst itch man
"You can't itch inside your body"
The itch at the back of your throat and in that section between your eardrum and throat: "And I took that personally"
and those rare moments when your cuticles start itching and you can't figure out where
I hate those and I actually had one yesterday

When I was 28 I was diagnosed cancer, Grey zone lymphoma, and my main symptom was the most intense full body itch you can possibly imagine. I could only sleep for 2 hours a night. My legs were full of bloody scars from all the itching. I went to the hospital and they told me I had cancer. 7 years later and by the grace of God im cured, but they still dont know why some forms of lymphoma cause the itching. Some people get the exact same cancer and have no itching at all.
That is quite interesting
Glad to hear you are doing well.
Hope your still doing well

My story as an eczema veteran:
Eczema is such an annoying life long condition. My dad had eczema and his dad before him and I’ve spent most of my life scratching, I have permanent scars on my neck and the creases of my arms and legs and I think I’ve pretty much had a rash on every place on my body(yes even there). When I was young I didn’t know how to handle it, and I was pretty embarrassed and would wear long sleeves to hide my arms and people would always ask me if I got burned or beat up. I noticed it comes about with stress and weather changes, even sometimes when I travel. Anyways the point is it’s manageable, there’s been points in my life where I’ve gotten my body free of any rashes for years on end. It’s really a slippery slope both ways, the less rashes I had the less I felt like scratching which gave me less rashes. I have never taken any medications for my condition. I take Luke warm to cold baths, wear mostly cotton or skin undershirts, I use hypoallergenic soap/laundry detergent, and I only use ointment (aquaphor) once a day after a bath, slowly using less as rashes subside. Sometimes to make my skin less red in certain parts I’ll dab the area with a cool damp towel and follow up with light ointment. I make sure to keep affected areas out of intense sun, cold, wind, or humidity. It can be defeating when it clears up and then one sweaty uncomfortable night destroys all your progress but don’t stress, trust that you skin can heal and try to put your mind on something else. Stress can really hurt you skin and try to find other ways to take out your stress, gym, meditation, writing your thoughts down, talking with people. Sometimes I wear clothes to bed to prevent my unconscious self from sleep itching. The urge to itch is strong I know it can feel sometimes like even getting shot wouldn’t be enough to relieve it, but it’s possible to fight it, distract yourself and it will eventually subside or just try lightly rubbing the area, speaking of I always keep my fingernails filed and short. You don’t have to suffer, it’s possible to get rid of it just be proactive and allow your body to heal and eventually one day you’ll forget your have eczema. Finally be open about your condition, most people won’t judge you, some won’t even have noticed, and all will only offer to help you. If any of this helped even one person I’ll be happy, good luck!!
Did you ever experienced some sort of skin color distortion, because I used to be a very light skin person but ever since the chronic ezcema hits around 80% of my body below neck are way darker colour than it used to be, and it doesn't even look natural compared to actual dark skinned people, and it's even worse since there are still small patches of skin where its still the original light colour
@@minglin2814yess
They called me hangman
(not really, just from time to time i get asked "were you hanging up yourself?")
You honestly have no idea how seen I'm feeling right now. Thank you. It's frustrating sometimes when I have to deal with it almost on a daily basis, especially because I have such sweaty hands. I used to hit the gym but the gripping on all the metal made it worse :( anyway recently I've been feeling so much better because it's winter and my eczema is mostly triggered by heat and sweat. Thanks again!!! I hope it's better for you nowadays!❤ have a lovely day.

My former boss’s wife had to have her arm amputated after a terrible car accident years ago. She said she could have full days experiencing phantom itching and that it is psychologically tormenting. She’s always been a genuine positive light but that is the one thing she says she truly struggles with.
Did she try the mirror trick?
the itchy feeling is the worst yet the pleasure the comes from it is unbelievable

Loved the drawings in this video! 👌🏼🏆
Anyone felt itches in a part of your body but when you try to scratch it the itch moves somewhere else???
Kinda. For me, I itch a part of my body and it doesn't stop itching. That's when I realise I'm itching the wrong part of my boy and it takes ages for me to find the REAL itchy spot. If this is what you mean, then yes xD
Well for Eddie when he Scratches the itch it Moves to his Balls 😂😂😂😂

David Ndiulor True.... XD

TOTURE......
more information than the "It's okay to be smart" video in half the time, and you actually managed to answer the question better than they did.
Personal experience tells me that itch is a subset of pain. Of burning pain, specifically. When I was 12 I had an allergic reaction to milk that caused the skin of my hands to swell and itch. At first it was a slight itch, then it intensified, and then it gradually transitioned into burning pain as the reaction became worse. Though, I don't remember if the reverse (from burning pain to itch) was also true, when I was treated with antihistamines and the sensation subsided.
I do remember, though, that a mild sunburn caused itch and a more severe sunburn caused burning pain. Also, a single mosquito bite causes itch, but one day, after a walk in the woods, I came home with dozens of mosquito bites on my back, and I felt burning pain. So, why would the same stimuli at different intensities cause different sensations? Because those sensations are actually one and the same.
I'm itching like crazy now, thanks Ted!
That escalated quickly.
i'm angry at Ted, now my head feels like it's crawling with thousands of fucking bugs.
Ditto!

Who hates when your at the barber and you experience itching
“You’re itching right now aren’t you”
Did this kinda scare anyone else with how accurate it was?
That was completely wrong for me.
I was scratching my back
Same for me.
I watching itching myself and I didn’t even search for this video.
erm nope
I swear every time he said "itch" I got an itch.
Haha, funny
yo same
That must be a lot of itches
@@mightypurplelicious3209 same I left the video half way and I came back to do this video
Right!!!?
semi fix to itching is to numb the spot where it itches, if im in the shower i just switch it to the coldest possible setting and point the shower head to wear it itches (sometimes i just stick my whole body in). You could also put an ice cube on the spot that itches but it can be too cold. Hopes this helps someone as much as it helps me.
If you haven’t done allergic reaction test, you don’t know what itchy feeling is.
*Straching you bc why not*
now imagine, having a personal hell called eczema. having the itch but not being able to scratch it in fear of innfections and tearing your skin apart. i hate it so much :(
Rad try rubbing it back and forth as fast as you can without damaging the skin, it might not be the perfect solution but it'll help
I had a class mate who had it, he used to slap the location of the itch to avoid drawing blood.
Weirdly enough my girlfriend asks me to slap her butt like that but she doesn't even have eczema. Wth Stephanie...
2nd3rd1st LOL
Huh I've had this since I was a little kid. Just checked and its all gone. I hadnt even noticed it fading away. It was really bad 3 or 4 years ago. Anyone else have this? really weird I didnt notice until now.
+Chris Nelson Could this be a bad sign. Like maybe my body is fighting something much worse and cant be fucked to mess with my skin.
“That’s why we don’t experience itching inside our bodies” my throat: Ha u wish
Nicholas Power the worst is when it’s inside your ear and the only way to deal with it is to cough because the same nerves in your ear also run by your throat and it causes an itchy throat.
huh
Kalisska Sky Lol I experienced that, I hated that the most
😂
The lining of your throat uses the same tactile sensation system on the outside of your body, since technically your throat and mouth are exposed to exterior elements.
that itching sound was legit some great ASMR.
To me, Scratching n itching sometimes it's comfortable and soothing as stretching
I don't wish it was not a thing I just wish it wasn't such an irritant at times. Loved this video thanks Creator
do you ever just slap the spot when the itch just doesn’t go away?
I kiss it. The itch goes away 🤗🥰

I have eczema and it affects every aspect of my life and you know the worst part isn't itching or lack of sleep or ruining all your clothes with blood it's when someone tells me something about my own condition that I've heard a billion times like "don't scratch" or "try (insert random advice"
I been thinking about this question for a few days now, how convenient

Anyone ever felt like inside of your body is itching sometimes?
Lizzy g yup
Lizzy g sometimes after I sneeze. I get an itch on the the inside of my right side of the chest. because I don't scratch it it lasts for hours. the best. can do is pound on my chest.
It feels like a hole is through the side of my mouth into my ear that itches like crazy.
SAAAAAME
I feel itchy inside my thigh every day ..it feels so bad that I can't scratch the itch..I need to hit the part that itches with my hand as hard as possible to scratch the itch inside my thigh.

Everyone has 31 "senses" and don't even know it. It's 1 of our "senses" we have a "sense of itching. We have a sense when we're hurt, the sense to cry, the sense of pain. It's a feeling.

Nothing is more uncomfortable than resisting the urge to scratch your head while you're getting a haircut

The animation is awesome!
You forgot to mention that scratching can be related to the "getting rid of" dead skin.
Also, on certain medications like Accutane my eyes were itching. All I could do was to close and rub them.
I have really bad eczema and the urge to itch it is so overwhelming that I actually make myself bleed... And then keep itching. It's gotten so bad that sometimes I wake up and find that the sheets are covered in blood because I've been itching during my sleep...
I've tried using ointment to get rid of my eczema but whoever it disappears in one area it just pops up somewhere else on my body.
The most common time my eczema flares up is during sudden weather changes. I also think that the ventilation system in my home contributes to it. Unfortunately my parents don't think anything is wrong and just buy more ointment. I think if I use it too much ill just become resistant to it.
The worst place I get eczema is on my face. It really affects my self esteem because I just have rash patches on my cheeks or forehead or on the corners of my mouth. The most annoying place I get it is on my hands because when the scabs crust over it really hurts to bend them because then it opens up the wounds again. It's really frustrating because I play trumpet...
Okay rant over. Hopefully someone can relate to this 😅😅
Jordan Hauser
that has been happening to me since I was 8 I'm 12 now but every time it bleeds I could get infections, the docters give so many creams but they dont do much sometimes I wake up this my sheets in blood from my arms and legs sometimes neck so I have darker sheets now
I have it on my eyelids it makes me look older
Jordan Hauser I can definitely relate I bleed from scratching it too
Jordan Hauser
I'm not a doctor but have some experience in this. Please research turmeric, apple cider vinegar, epsom salts, Manuka honey and bi carb of soda. :)
Jordan Hauser I think I have eczema too. I had never actually put a name to what happens to me until I read your comment, thanks. Mine is not as bad as yours, but my thighs and arms are always itchy, and it won't stop, doesn't matter how much I scratch. I often make myself bleed while scratching, and it keeps spreading. It's happened to me since I was a little girl, but now it's kinda getting worse. Hopefully, doctors will soon find something to make it stop. Good luck with everything!
I have not scratched for the entire video!!
unfortunally, after the video stopped I had a severe scratch-need...
Me neither
I did itch these whole complete video.

gaydicks420 I itched when I watched this video too
I like how even the art style "looks itchy"
Always wondered what the purpose behind the itching sensation was, and although there isn't a concrete answer I would say this video kinda scratched that itch.
Anxiety and insomnia make me itch all over my body. If I lie in bed restless with the intent to sleep, I'll itch in random spots, like 5 to 10 spots that I need to scratch, and it loops over and over like a pattern. When I need to go to work and leave the house, my legs itch so intensely that it's hard to walk. I sometimes need to wrap my legs tightly with a bath towel until it stops. This leg itching started after pre-school, early elementary, and never left me.
