I have been doing cold exposure for more than 5 years now and have learned so much. It also transformed everything in my body and mind. I am so enthusiastic about it that I kept on dragging people to open water in the winter and I now have an app group of about 40 people. We all have cold water baths at home and sundays we meetin water to take a cold plunge together. Everything in this episode is true, the benefits and feeling are huge. But this episode touches just the surface and makes mistakes. First they immediately put him in blankets when he comes out of the water. This is nonsense, when you come out you can just walk around in cold weather and don't feel a thing. Nor will you get hypothermia. Second the warming up is all wrong. By doing a deep squat you use your leg muscles to warm up the blood. By doing "Viking breathing" you also use your lungs to warm yourself. The effect is astounding. Yes you can use your lungs as a heat source, there is some Russian study about it. Third and not not mentioned is the dopamine effect after a cold plunge. You will feel so happy and relaxed as an after effect, it's totally addictive. The dopamine rush is 250% over normal! Fourth is an annoying and dangerous mistake to let him swim without handshoes and a neoprene headcap. Yes that will not look good on film, but it is eesential when you go wild swimming in cold water with your head in the water. It is quite dangerous and that's why he didn't feel good afterwards. You can do this but keep your head out of the water or wear a neoprene head cap.
