The benefits of cold training in water, ice and air have been touted throughout history. The ancient Greeks used cold water for relaxation and therapies. Hippocrates wrote about cold water as a pain-reliever and Napoleon’s surgeon recommended ice and snow to relieve pain during amputations.

Scientific investigations started much later, though. In the 1960s, the focus was on post-exercise recovery before it shifted to research about survival in extreme temperatures. Only recently has metabolic health come into focus.

While there are many benefits (as detailed in the section research) cold exposure is not without risks. That’s why we follow emerging science closely and have a leading European cold researcher on our board. It is our goal to provide you with the most up-to-date, scientifically sound information as well as with current trends and practices, including some that have not been thoroughly scientifically investigated but have proven effective in real-world training.
