I am a huge fan of neuroscience and biohacking. Cold therapy, cold plunges can change your life.
Some benefits at a high level: speeds metabolism and fat burning, builds tolerance, helps to regulate dopamine levels, reduces inflammation (why athletes do it after a game/match).
It has scientifically proven benefits if you do it early morning, even before caffeine, kick starts your metabolism in a way that reduces your desire for food, allowing your body to burn yesterday's calories longer.
its not easy....I like to let out a good series of yells when i do it in the AM in the shower...when at the performance center and doing their cold plunges i try to contain myself!
Here are a couple links to two highly respected folks....Andrew Humberman is a badass Standford neurologist and Wim Hof is a Dutch extreme athlete.
I like the Generator Athlete Lab
