I remember Rickson Gracie training in the mountains of Japan when he was preparing for the world title doing the cold plunge

Some truth to what he said.
Makes you feel more alive.
When i trained Muay Thai many years ago a few guys spoke about it. One night after training we all decided to jump in a pool when it was like 40F degrees outside. It was a crazy feeling, like being slightly electrocuted. Hard to explain.
But i remember getting out of the pool and i had this amazing buzz for a while. The same buzz you get after a heavy sparing match where you take a few good shots.
Makes you feel alive.
Same feeling i got after getting caught in a bad ice storm in the mountains. Was on the last mile of a hike and the storm came in, temp dropped 40 degrees in a few minutes. 50 mph winds. The last 100 yards were unbearable. When i got back to the cabin and got warm again, i felt like i had just been reborn. It was kind of odd.
Definitely kicks in some endorphins.
