So, recently on Joe rogans experience podcast Dr. Ronda Patrick appeared. And Joe explained that he had been doing cold water immersion to benefit his post work out regimen to which he appealed to Dr. Ronda for more info on the why's and the wherefore.
Dr. Ronda eloquently stated that Norepinephrine production is increased by cold immersion (according to a mouse study) and that the subsequent benefits are definite energy increase, clarity of mind, and overall feeling of well being.
Joe, during this podcast confirmed these 'effects' as far as he could perceive them from his cryo-therapy sessions in sub 100 degree cold immersion for seconds at a time. Apparently, the stressors that cold immersion brings from the aforementioned therapy are followed immediately by synaptic build up and subsequent norepinephrine production (also confirmed by multiple mouse and a couple observational human studies related to sports).
The good Dr. then went on to include that she wasn't sure about the exogenous supplementation of Norepinephrine since it is considered a re-uptake inhibitor and can stunt the bodies endogenous production.
The conversation was quite intriguing and brings the following considerations into play.
What are the absolute best ways of increasing endogenous Norepinephrine production and to what, or any degree, is it safe? Is there an upper limit? Etc.
I know exercise helps, I know healthy eating helps, and I know cold immersion definitely helps, but for those who do not have access to cold immersion facilities, what are the best ways, and what of supplementation? Are there ways of supplementing without damaging the endogenous production of the protein?
