In this video, Jonathan from the Institute of Human Anatomy discusses the main benefits of Cold Plunging! He discusses the adaptations it can cause in brown fat, potential changes with inflammation & immunity, its influence on mental health (stress, anxiety, and depression), and improvements with exercise recovery. He even discusses if cold plunging can improve metabolic efficiency, blood sugar (glucose), and insulin sensitivity. He also provides protocols on how to incorporate cold plunging into your weekly routine!

    I have been doing cold showers 17C/54F 3 minutes every other day for about a year. I get about 6 hours of heightened “gotta do stuff” from it. I start with a hot soapy shower to wash and then instantly turn to cold. I find it much more enjoyable to get out after cold than from hot as well. You feel neutral rather than cold.
  • @drip369
    I love it, makes you more resilient to the cold because your brain now knows the difference between being cold and feeling cold, the immune system benefits and the nervous benefits are top notch
  • @WinWingLP
    Been doing it for 5 years now because of panicka ttacks, together with breathing exercise and helped me much more then any kind of drugs (weed, xanax, anti depressants etc.) ever helped. Thanks for the video^^
  • Also, you’re a champ for doing that for a thumbnail 😂. Your channel is helping this student of forensic science. Thank you so much!
  • I got into it a while ago and I suffer from anxiety and depression. It has definitely helped me with motivation and wanting to engage with the world. It pushes back that feeling of being cold and just wanting to rug up and protect yourself from the outside world. You feel like you have a fire in you that fuels you. It helps with anxiety for me because it helps me control my own internal terror. Having a daily 3 minute cold shower requires me to control the physiological and mental stress to get to the end and just knowing that I can quiet the panic in myself and breathe through it has been really good training for other situations. If I start to panic in the world I think back to my showers and find I can breathe through it and manage. I can’t recommend cold showers enough. 3 minutes of discomfort is nothing compared to what it can help with. My weight has improved and my energy levels are up too. This helps me with exercise and all of that feeds back into better sleep, arguably the key to everything.

    Cold exposure changed my life. Been doing it regularly for about 4 years. 33°F-35°F for 3:30 min 3-5 times a week. Started with ending my usual showers with 30 sec of cold and worked up from there. Great video and excellent summation of cold benefits and protocols.

    Here in Siberia we massively follow a tradition of water-baptistry mimicking the Iordan one. Popes cut some holes in ice-covered rivers and people plunge. Air this day is usually -15°C-25°C. People plunge as it's such a hype the next day, followed by such a pilgrimage to hospitals, as people catch heart attacks, strokes, pneumonia and so on. I did it once, caught my adrenaline but once is quite enough. There's a long list of conditions and diseases to be considered before plunging, one needs to be sensible

    Great inspiration. Living in Northern Ontario I am no stranger to cold including plunging into lakes with ice on it - but that was more about “ego challenges” back in the day. In my newfound journey to a healthier lifestyle I realized mental fitness is just as important as diet, exercise, and sleep. Mindfulness is the glue for all aspects of lifestyle. Cold showers, to me, have become an enhancer and measurement of my sustainability. It enhances my mental strength by recognizing signs of stress but more important, how to mitigate it. For example, what are you really feeling and is it that bad (especially while you are IN the moment of stress)? Over time the shock is diminished and the length of time increases. As for measurement, aside from temp and duration, I can feel how much better I can control the reaction to the cold. I am at the point where I can decide to relax or “freak out” and this is a (not the) measurement of my mental fortitude. Why was this cold shower so hard, or easy today? I mostly do it in the evening because the release of “stress” once you get out, dry off, and get into bed just makes me relax and fall asleep faster and sounder. Note, I am not the “stressed person” type, but when I get into stressful situations I am better aware that I can control emotion more effectively (ie. stronger mental fortitude). This mental fortitude transcends into lifestyle choices regarding food choices, cravings, exercise and general motivation. As you know, saying no, or getting off your ass can sometimes be really hard decisions - especially when transitioning to a sustainable healthier lifestyle. Again, this is me and might not work for others, but an example how small things can go a long way. It’s not just a stupid cold shower.

  • @ignatalia
    This would explain why my mom would submerge me in cold water when I had a temper tantrum 😂 it worked very well. Now, almost in my 50s, every time I feel stressed I take a cold shower. Now it all makes sense. Thank you guys for this very useful and educational videos. You make everything so easy and understandable for non-doctors lol.

    Unfortunately I suffer from a chronic pain condition and have been trying to get this information for some time. Thank you! I love this channel and what you folks do.
  • @Frafra766
    I live in Finland and here is very common to do this. It starts already when you are a baby, mom's will put you to nap outside during the winter for some time. Most houses have a sauna and I believe most people do sauna once or twice a week (I do 2 times a week) and if there is a possibility people would do cold plunging in cold baths (0 degrees Celsius baths that you can find in most spa), rolling in or rubbing snow and dipping in lakes (the hole in the frozen lake is called avanto). Usually you do this as soon as you come out from the sauna being steamy hot (sauna is done at 80 degrees Celsius), and yes, naked. Then you can run back to the sauna to warm up again. :)
  • @rosaquinnhere
    I've just done a sea swim this morning after our frosty spell here in the UK! The sea temp was about 8 degrees C. Felt amazing!
  • @bonniecline5014
    Ive been using cold plunges for 20 yrs. I love going from a warm hot spring into a cold pool plunge. I live in CO in the mtns where the natural waters are always cold. My cold plunge in summer is in a deep creek. I know not many people can stand it...but i love it & my system is used to it after 20 yrs of doing it❤
