Why Saunas & Ice Baths Are So Good For Your Health

What happens in the body when you do an hour of hot and cold immersions? Why do you consider it to be so powerfully healthy?

There's many reasons why it's so good. First one, exercise your cardiovascular system. Because when you go into the heat, your blood vessels dilate. When you go into the cold, they shrink, because the more they're exercised, the stronger and healthier they will stay. Then the intensity of the heat will have an effect. Very hot sauna like 90 degrees centigrade, that gives a heat shock. What that does is actually ST stimulates growth hormone and also stimulates stem cells to awaken. So does the really cold. Extreme temperatures basically stimulates stem cell activity. The fast hack for it is to do a hot shower, five minutes and then five minutes, very cold shower, and just rotate. Just start with 1 minute, 1 minute, 2 minutes, 2 minutes. Like that.
