Cold-Water Immersion and Cryotherapy: Neuroendocrine and Fat Browning Effects

In response to cold-water immersion and similar techniques like cryotherapy, the body increases circulation of norepinephrine. This physiological response sets off a cascade of adaptive effects with extreme rapidity that affects metabolism, the brain, and genetic expression.

@@WaterspoutsOfTheDeep I have a lumen photo unit and I'm getting ready to use it on my shoulder. It has really help my back. but this injury has been persistent for about a year. You just reminded me that I have that unit. Thanks! If you are interested, in about 2 weeks, hit me up and I'll tell you if it helped.

[@WaterspoutsOfTheDeep]

@@Mr25thfret I know they work almost immediately in under 5 minutes. My mother who has back and shoulder issues from a car accident uses them. I have used them too. It's just a 54watt led 850nm bulb from amazon you screw into a light fixture. The near infrared penetrates deep into tissue a inch or two it is basically the same across the board as red light and it's benefits except better because works deep. Red light 660 nm and 630 only goes a few mm deep. It almost instantly takes away inflammation. I do it after face peels, needling, and other serious face treatments and it immediately cuts the redness and swelling you can see it. The ICES PEMF is even more effective and can reach deeper and they work differently so they can work together. The ICES PEMF is what is used on people and animals that have spine surgery and broken bones and other serious deep injuries to heal fast and after 15 minutes dramatically cut the pain because it drops the inflammation locally. I had food poisoning awhile ago it helped a lot to calm the gut discomfort, also heart palpitations and it reduced it a lot right away. Also I love it after doing alot of work with my hands and my finger joints are sore and swollen. These two things are amazing investments. There are a lot of other things you can do with them too. Like the near infrared there was a study that showed it increased muscle growth something crazy like 40-50% because it increased the rate of repair after weight lifting. No supplement can even remotely come close to such results. Yet with the LED bulb it's just one investment of like 40 USD per bulb. Thats why I recommended them. Cold therapy won't be giving anywhere close to the same results and it's really a pain and uncomfortable. These two I mentioned are extremely easy. The ICES PEMF is amazing because before if you wanted real actual functional PEMF treatments you'd need to basically go to a hospital that had a 15k dollar machine or a practice. But a NASA scientist patented a compact handheld low power way to get the same type of effects with induction of the PEMF. He owns the patent and sells his own machines pretty cheap compared to the companies that lease the patent and make their own. It's like 400-500 USD vs 2000. There is a million things that can be said about both. But I already wrote a book in the comment section lol.

Check out the feldenkrais method

[@rachellezeiders5283]

I’m so glad you posted this. I need to start doing my ice baths again. I still do cold showers but it is not quite the same as 34* F ice water. I started this for my mental health (severe depression and anxiety) and a whole host of autoimmune issues including constant pain and such a severe cold intolerance that I would spend days in bed shivering if it was below 85. I live in Southern California and dreamed of moving to a place that never got below 90. My experience with ice baths was absolutely incredible! The trick is to tough it out for 30 seconds to a minute with lots of deep breathing. After that I was able to work my way up to 15 minutes in the ice! I get into almost a meditative state and then stay as long as I want. Another trick I use if I start shivering in the ice is that I focus, breathe and get myself under control. I do not jump out! I tell myself that I cannot get out until I get control over myself. (I’m not telling anyone else to do this, it’s just what works for me). This makes all the difference for me. We have control over our body and mind! When I decide to get out, I am calm and not shivering. To spend my entire life feeling horribly out of control to knowing that I am in complete control is so empowering that it’s hard to explain. All of the health issues that I had experienced for years and the mental health issues that I had for as long as I can remember all just kind of faded away. Life changing! I am a mother of 4 sons, married, in my late 30’s and of thin, small stature. Definitely not someone who looks tough and strong. Anyone can do this! I promise! One tip is to watch a lot of Wim Hof videos, interviews, ect. Wim Hof videos changed my life! I found a video of Wim coaching someone getting into ice water and play that on my phone while I’m getting into my ice bath. Having him tell me to breathe and that I am in control makes me feel like I can do anything! Breathing and getting into a meditative state is huge for me! If my kids interrupt me I usually will start shivering. I have to stay focused! I get out when I am in complete control. I am calm and not shivering because I am in control! I do the Wim Hof exercise after to warm up my body and then I go about my day. When first starting the cold showers it is unbearable I know but read about all the benefits to the body after 2 minutes in the cold. If you can get past the 30 second mark you can get up to 2 minutes pretty quickly after that. Cold therapy has stopped anxiety, panic attacks and depression in its tracks for me. If you feel a panic attack coming on get in cold water and I bet it will stop immediately! I know I rambled on and on but I hope this will help someone! I will be starting my ice baths again this week to get control again over some of the symptoms that have crept back into my life.. Good luck to all!! You are in control! As Wim would say “You are entitled to be happy, strong and healthy cause the rest it b.s.!!” 💙

His method absolutely makes me feel better and also just watching KZbin videos/interviews of him is so inspiring and helpful. To know he has felt the darkness of this crap and now is so powerful, in control and full of life helps a lot. He makes you want to live again. Really live….like he does, with happiness and strength. I started being able to really separate my mind, body and spirit. It’s amazing to discover that You (Spirit) have control over your mind and body. That’s the only way I was able to actually get into the ice was to tell my mind and body that they were no longer in control! I was in control and they were getting into ice water now! I also stopped saying “My” anxiety and depression because it was not mine! I detach from that crap as much as possible and say (the) anxiety and depression if I must talk about it. This method can and will absolutely help anxiety and depression. Start ending your regular shower with 15 seconds of cold and work your way up from there. Breathe. The 2 minute mark is where the magic really happens. Something shifts and somehow even though it’s cold it doesn’t bother you and you can stay longer. Most of us start looking forward to our cold showers everyday because you feel so good after!

I started doing ice water swimming in a creek on a friend’s property. I found my best success by preparing mentally in advance. If I thought cold, my muscles would tighten, reducing blood flow and I would be so cold. I learned to relax using Wim Hof breathing and mentally prepare by thinking of it as a summer swim. I found this to be extremely helpful and could easily remain submerged for 10-15 minutes. My favorite time is when the air temperature is below zero F. It’s really incredibly exhilarating to come out of the icy water and feel warm in these temperatures! I’ve never felt so alive!

@@Soulflytribe04 Your right butAdhd does exist mate. It is a symptom of trauma. Trauma is stored in the body and causes excess dopamine, cortisol and adrenaline and as a consequence the brain is in a constant state of flight and flight and cannot focus because it thinks it is in danger. Cold water exposure places the attention from the head to the body activating the parasympathetic nervous system and calming the mind and body down.

[@sentientexplorer]

@@Soulflytribe04 I agree with everything you say and ADHD is a symptom of a cauldron of issues. Lack of sleep and poor diet causes inflammation and that in itself is a form of stress and trauma.

[@treewalker1070]

I used to live about a half mile from a river. I swam in it every chance I got in the summer, and occasionally in the winter, when the temperature was below freezing, Well, didn't exactly swim in it then, just plunged in it and thrashed around frantically to get my blood circulating and got out after a few minutes. After that, standing on the snowy ground barefoot in a wet bathing suit, I felt supercharged, not cold at all. I felt like if I could do every day, I would be immortal. This past year, partly because of those memories and partly because of things I read on the internet about the benefits of exposing yourself to even merely cool weather, without a coat, I took up jogging in tank top and shorts every morning. I started in the summer, when the morning temperature was about 60 F (about 15 C). My ambition was to condition myself gradually so that I could go out dressed like that even in the winter when it got below freezing. And it worked great! By winter, when the morning temperature was around 25 F (about -4C) I was doing it. My skin stung, but the cold didn't seem to reach me inside. Except I had to wear thick gloves on my hands or my fingers would get numb and stiff. I don't know about doing the ice baths, though, for two reasons: first, my poor hands can't take the cold, and second, it all seems to depend on physical activity that gets my circulation up, and in an ice bath you'd be immobile. Ice baths are not practical anyway if you can't make quantities of ice. But Im a big believer in the rejuvenating effects of cold, have been for years. BTW, I'm 70 yo. Matter of fact, there's a vid on KZbin called "Swimming In Miracles" where this guy had terminal cancer and decided that on his bucket list was an ambition to swim the length of the Willamette River (the very river I used to swim in). It took him a couple of weeks, and afterward it turned out his cancer was in remission. He attributed that to all the spiritual lessons he was getting about nonresistance and love and so on -- surely part of it. But there was something else. Although it was summer, the water was about 50 F (10 C) and nearly every day, despite being in a wet suit, he would eventually start to get hypothermia and have to be fished out of the cold river for a while to warm up in the sun. He didn't make any connection between that and the remission of his cancer, but I feel they were connected.

[@barbarafairbanks4578]

@BenBenson I kind of disagree with you, but is just my opinion (educated guess). The factors of hormesis that are beneficial to mitochondrial health (especially), are a short, temporary shock to the body (e.g. cold exposure), which he would certainly be getting just going out into the cold, lightly dressed as he was. There's the shock, right there (generating epinephrine), and doesn't need to be any length at all - just that short shock will give the nrrvous system a good shot of epinephrine. The other beneficial factor to cold exposure hormesis is 'shivering' - this generates brown fat which is physiologically beneficial, as well. And, it matters not that the body is heating up with exercise because this happens AFTER the body has experienced cold shock a period of shivering (which I have to assume was present in the beginning of h8s cold exposure). Also... about the body's thermogenesis with exercise - The body will be heating up very quickly with cold exposure anyway - exercise or no exercise - that's why we shiver in the cold. Shivering is 'micro-movement' of the nervous system - e.g., 'exercise' for the purpose of thermogenesis...(heating the body).

With 2 going on 3 years of practice, I can handle colder and colder temperatures for longer periods of time before shivering. I didn't know why until now!

Dr. Patrick, kind regards and thanks for getting this science out for people. I am on a health regiment now for the last 4 months. I am on a intermittent fasting 5eat/19 not diet. I wake between 5-6Am automatically from a good 8-9 hour sleep. I light the fires in the heaters then go out to my Sauna that is still about 100F inside. I strip naked and then immerse 100% in 33F cold water for about 3-4 minutes. then let the cold breeze send me to shivers. I dry off and dress for the day. next I have my first Coffee with prebiotics, and spent my day very productive at work with super attention. When I eat it is healthy foods without simple sugars. the next is to light the Sauna and while it is heating I spend the 45 minutes doing core strengthening exercises. then I ice bath again then Sauna at 180-190F for 15 minutes repeat 4 times and end on hot Sauna. This routine has changed my entire life. I should also mention I am now closer to my physical condition when I was 30 than ever - I am well over 60. Thanks again.

This is very interesting and relevant to research I’ve been doing in horticultural science. In plants, particularly pertaining to seedlings, stressors can be introduced through controls like heat, light and water availability, not so much to induce chemical/biological responses, although they can occur, typically it is done to prime the seedlings for more robust growth when the controls are optimized and no longer inducing stress on the plant, which in turn because of the stress releases plant hormones and the precursors necessary for catalyzing the future growth through the optimization of the controls. I’m definitely going to try this out again, and maybe you could do an episode on the “nofap” phenomena that, for many men at least, is part and parcel of the cold shower practice. Thank your Dr. Patrick, I love your work, research and insights especially through your podcast format, stay awesome!

[@calbrock6302]

I used to grow a small amount of cannabis and used to purposefully stress the plants by snapping leaves, and allowing the plant to dry out a little to the point of wilting then I’d feed and water them. My reasoning (without any scientific basis) was that after the stressing and withholding of water when I did water and feed the uptake of nutrients would be better and the stress of snapping leaves etc would encourage strong and resilient growth. I miss growing weed, I got more fun growing it than I did smoking it.

It makes a huge difference and can postpone hypothermia and be a lifesaver. I’ve made my own comparison refraining from eating oily fish and notice my fingers freeze as well as slow down much faster in cold water immersion compared with eating oily fish before going outside in the cold river ice water. Also I’ve used the Wim Hof principles since September of 2018 but immediately noticed just eating the oily fish and before taking a cold water plunge is easy. I go through all winter in the Penobscot River makes it easily tolerable. So can you explain or give any insight to this? So what happens when the veins,capillaries,blood vessels have this insulating high omega 3 oil that thins the blood in the body? What is interesting is the difference in withstanding the cold is dramatic in being a much longer duration. My own experiment was I refrained from eating oily fish 2 weeks and went in a horse trough middle of winter opening and closing fingers immersed in the ice water and the muscles froze up slowing down the movement in 3 min. Then I ingested oily fish and noticed it was easy to open and close my hands in 12 min!! That is 4 times longer so this is a dramatic difference. But what I find even more interesting is what Eskimos have by eating marine sea mammals that have a much higher fat to omega 3 oil ratio compared to oily fish. So by saying this is omega 3 oil responsible for the thermal warming properties of the blubber with minuscule trace amounts of omega 3 oil or is it something altogether different in the blubber of marine sea mammals that we do not actually know or understand yet? I have a track record and inventive in making my own fermented mackerel and herring since 2004. Always had at least 2 oz every day and noticed way before stumbling upon Wim Hof that I was warm in my shop in winter without heat. Observed this like 4 years previously. However I’ve always been super fit and conditioned with a low resting heart at 44 yo of 35 bpm and a type 1 juvenile diabetic. I weighed at that time 223 lbs at 5 ft 10 in tall. I’m less weight now at 190 lbs and 52 yo. Can you post a video about this or a explanation as to what the heck is going on? Also have you ever heard of Weston A Price and his book : Nutrition and Physical Degeneration or his research regarding nutrition and dentistry?

Ice bath #2 for me!! Day 1 lasted 64 seconds. Today lasted 2 minutes 11 seconds!!

Hi Rhonda! Thank you so much for the great info. I am a long time fan of yours. May I ask what program/company you use to add animation and edit your videos? I really like your format and would love to bridge the same style into the dermatology space.

[@wrenchingandwheeling1589]

Shivering as I watch this. Just finished a 20 minute plunge. Feel great.

[@MalMilligan]

I go through phases that last for months where I'm able to do a 2 minute cold rinse at the end of a shower. I've studied Wim Hof methods. But I loose interest in the cold showers usually in the winter months. Anyway it's good to know that there is scientific research into cold exposure and I'm sure I'll get back into it again soon.

You should try make it a routine, like doing it monday/wednesday/friday, and combine it with sauna. take a timer and make a sport out of it, so you compete with yourself on how long you can do it :)

[@tekbirrai4263]

Very convincing ! Thanks very much for sharing it !

[@billy4525]

Thank you so much for this information! I will follow you for more tips

[@watcherworld5873]

This video provides interesting reasons why I should finally try ice baths. Currently, the coldest thing I do is 1 hour run/walk shirtless in short shorts in 40F temperature. I notice that I don't feel cold at night when I sleep anymore. Of course, that could be caused by many other things too.

I have a fresh water creek running thru my property & lay back in the flowing water from April on…. Icy cold well water showers 🚿 during the winter & I let myself drip dry …. Feels A-M-A-Z-I-N-G!!! 😁

[@dravenstone8532]

I'm watching this to amp myself up to get in this bath

[@tym5583]

You are AMAZING. One of the only docs who has resonated with me. I really wish you or your colleges would reach out to a very small very intelegent and super human knowledge in type 1 diabetes also a super human and phsyic. Jay Sampat. If you could get him on your show and or for a small bit to help him out. He is extremely smart and educated like ya'll. Would love to see a colab l. It'd be a dreaaaam!

[@ketodiana]

Thanks for the great info!

[@richardprice9730]

YES reinforcing the intuitive subjective sense of this us really doing me good and mapping the different biologically effects the BIG problem is in doing it ,a veteran of 3 years stream exposure 1-4 degrees dependent on time of year to overcome the shear extremely unpleasant effect and not to revert to all manner of avoidance strategies IS the MOST diffic aspect of its implementation. I know believe me it is THE most diffic of all health protocols to initiate and continue on a regular basis after extreme cold water cold showers are just refreshing believe me .

[@waynecutler3830]

You're amazing, thank you soo much for all your help :)

[@brucebarton8767]

Another little bit of information: I've been swimming under cold water for 4 years & if you've ever HEARD YOUR HEART BEAT LOUDLY WHEN YOUR "EAR" IS ON A PILLOW, that "sound " is diminished GREATLY after years of submerged COLD WATER SWIMMING! OBVIOUSLY, my arteries have EXPANDED.

[@jasonc9423]

Dr. Rhonda Patrick is gifted! Loved her previous advice on Vitamin D... It made miraculous changes to my life. I moved from Hawaii to Canada and couldn't figure out what was going wrong both mentally and physically. Vitamin D supplementation changed EVERYTHING! Now I am going to take up "polar bear swimming" and see what changes occur! :)

[@frankreyes4]

Outstanding. Thanks

[@alexblue6991]

This is like my house just now I live in Scotland the gas and electricity bills are dubbing in price can't afford to put on the heating

[@justinchinevere2]

This is great information and I used to follow this girl religiously until she started advocating for the Covid vaccine

[@mattpope764]

Dr. Patrick, I love your videos and content! If I could make a minor suggestion - slow down the delivery slightly of these technical videos. Even those of us with great learning capacity have to pause and rewind to absorb everything. I'm sure you could expand your audience by making this slight adjustment!

Just click the settings on the video and select a slower play speed ✌️

Great video. How long lasting are the Norepinephrine and Dopamine increases?

[@foxybob222]

Moving to northern Alaska will be nice in cold winter, just step outside a few minutes LOL !!

[@bradmarcus6608]

and the production of heat shock proteins as per your previous lectures:))

[@michaelshanahan4965]

The complex where I live turns off the heater in the pool after Thanksgiving. Don’t know the temperature but it’s cold. Just slowly walk in and then head to the shower. Works great.

[@StateofKait]

Thank you! I’ve been doing five minutes cold dips a few times a week and I’ve noticed a decrease in my chronic pain. Amazing

[@SL-bu6qj]

When you say dip, do you go to a pool? Or bath?

[@KABSOOLH1]

I tested it and can confirm, the temperature outside feels like -2 or -3, temperature inside never goes above 15, I go run outside with 1 thin layer of body warmer and a t shirt and short I feel much better, more energy and very comfotable with getting cold, when i come home from running i have to open the windows immediatly because 14 degrees inside its too warm so i start working out with only under wear and windows open because otherwise i start sweating. i enjoy fresh air more than warm air now i can feel the different. by the way it's 14 degrees inside not because the heating is on, i dont know why but even when i leave windows and doors open for hours while its 0 degrees outside inside it does not go below 13. and when i close doors and windows it jumps slowly and stable at 14. the heating is off yes. Thanks for the informative video.

[@anzaborrego399]

I am a life long lentil and broccoli seed sprout eater, thanks to Dr. RP. Sometimes I finish off my showers with cold water...
