What is cold exposure therapy?
One of the biggest proponents of cold exposure therapy is Wim Hof who has shown you can improve your health, mental health and cognitive capacity with cold and breathing techniques.
The idea is to expose your body to cold and this creates a stress effect on the body and physiologically seen this trains the cardiovascular system, the sympathetic system, and probably much more.
Doing cold exposure can help with recovery, hormone balance and create mental resilience.
Should everyone do it?
Yes, most people could do it but not everyone should do it in the same way. Time and temperature will be very individual and requires training to get comfortable with it.
