      Same. It works 80% of the time. When it doesn't, eat some carbs (insuline calms you), and restart submersion with even colder water.
      I've had daily panic attacks for over a decade. I haven't found the cause sadly, but I try to at least find workarounds and bandaids when it happens.

    Want to lower your BPM, but don't want to hold your breath for over a minute and dunk your head in a sink of water???
    Placing ice cubes under your eyes (or mini ice packs from a Dollarama/Dollar Store) can have the same effect! If you are in a crowded place and think people might look at you strange for pulling out ice packs, carry around a plastic frozen water bottle. Nobody thinks twice about someone who looks hot and is simply placing an iced water bottle under their eyes to cool down.
    The mammalian dive reflex is located under the eyes and activated by a drop in temperature. This is a survival reflex designed to conserve your body's energy if you are submerged in cold water. So, instead of pumping blood to your limbs, it keeps the blood heated around your chest and keeps your organs warm. This increases your chances of survival. However, as we know, the body is not perfect. The mammalian dive reflex cannot tell the difference if you are submerged under cold water or if you are holding a cold cloth on your face. Either way, placing that cold temperature under your eyes starts to lower your BPM and conserve blood flow.
    While the mammalian dive reflex sends your body into survival mode, your brain is actually not sure what is going on. Your brain understands that the heartrate is lowering and that the body is calming down, but does not know why, so the brain assumes that we must be calm. That is why this technique also helps with anxiety, anger, stress, panic, flashbacks, nightmares, and more. By calming the body, we trick the mind into think that it is calm too!
    This is a tool that I used often as a student. I have test anxiety, so by bringing a frozen water bottle with me, I could hold the water bottle under my eyes and settle my anxiety while writing my exams!!
    Hope this was helpful!

    • @brodygagne7211
      @brodygagne7211 4 года назад +2

      The diving reflex is accentuated by cold water immersion, but it is obviously more effective when the entire body is submerged. In full-body immersion in freezing water, the bradycardia and peripheral vasorestriction associated with the dive reflex become significantly amplified (as long as you are able to maintain a relaxed state and not panic).

    • @alee3146
      @alee3146 3 года назад +3

      The reason for immersing the face is that the trigeminal nerves in the face are the active temperature sensors for triggering mammalian diving reflex. Breath holding changes your blood chemistry which is a contributing factor in the lowering heart rate response. Cooling the rest of the skin surface leads to peripheral blood vessel constriction which shunts blood with the remaining blood oxygen from the limbs to the more high priority heart, lung and brain tissue needed to sustain survival while submerged. The lowered heart rate and relaxation is in tune with reduced oxygen consumption, kinda like hybernation or suspended animation sort of.

      I am no doctor - but I believe the ability to relax your body and mind can be trained well in cold water - but also the opposite - so when you immerse yourself in cold water - do it with a relaxed body and mind - slowly not forcing.. accepting not fighting... then I believe Cold water can be one of the great healers :)

      @@cameronsharp2297 Deep breathing and breath holding alone can also lower your heart rate. The first trial he can hold his breath let's say 1 min and record his heart rate. Trial 2 he can do it the same exact way with the cold water. He can then compare the two numbers and calculate the difference. What he did in this video instead is he compared his normal heart rate to the cold water heart rate. A more accurate way would be to compare his breath holding heart rate to the cold water heart rate to account for that variable. Again why? As I mentioned above, breath holding alone can decrease heart rate. People may get a false sense that the cold water is solely responsible for the decreased heart rate he displayed with the way he did it in the video but that is not the case, there are other variables involved that could be accounted for. That is what I meant by my original post and it appears to be clear to most people except for you. I went into respiratory arrest years ago and I have experienced true Brady cardia. Don't tell me I don't know what this is. And don't call me out like that to throw me under the bus, not cool.

      [For panic attacks] Try filling your mouth with water, hold your breath, sit down and maybe lean down putting your head between your knees. And then take a breath through your nose when you need to. I found that it stopped the onset of a panic attack just several days ago. I was fixing to rinse my mouth and gargle when I felt the panic begin to start up. I sat down and just swished the water, (1/2 peroxide and 1/2 water, be sure to spit out peroxide/water), around my mouth and held my breath until I had to breathe, and my panic began dropping. It worked better for me than breathing into and out of a paper bag. Which never seemed to help my panic attacks. I then went and took a Paxil which I had skipped for a few days as I am trying to wean to a lower dose. I heard that 5mg Paxil can stop panic attacks. The 20mg tab seems to be too much interference with my other med. [For high blood pressure] A man from my neighborhood said to try a teaspoonful to a tablespoon of lime juice with water to bring down blood pressure if it spikes up or is too high. I tried lemon juice in water and it did bring my blood pressure down. It was from the bottle of concentrated lemon juice.

    World record is 20 minutes, a regularly training free diver can do over 3 minutes.

      Nope WR is not 20 min. Yes, even a beginner Freediver will quickly reach three min with the right coaching. This video is a display of the MDR.

      Yes for sure - whenever you put your head under water and hold your breath it is advisable to have someone looking after you.

    any heart rate below 50 is way too low... below 40 is almost incompatible with life.
