Cold exposure is a powerful tool to influence human physiology, including the autonomic nervous system, that people can use to enhance health.

“The human potential of his physiology is far beyond than what we exercise right now. And because of this comfort zone way of thinking, we think we can control nature, but we do not control the inner power anymore, which is the physiology, which goes far deeper than we exercise right now”

Deliberate cold exposure is an effective tool for elevating adrenaline levels and training the ability to remain calm and maintain clear cognition under stress.

“getting into a cold shower for a minute or so to elevate your levels of adrenaline and learning to either use your breathing you could do physiological size or to distract yourself or whatever tools and approaches you need to be able to stay calm while you have elevated levels of adrenaline”

Deliberate cold exposure increases norepinephrine and stimulates mitochondrial biogenesis, though timing must be managed to avoid blunting muscle hypertrophy from resistance training.

“it's really important that I also just want to point out the best way to increase mitochondrial biogenesis in muscle tissue is actually high intensity interval training, way more robust than deliberate cold exposure. With that said, deliberate cold exposure does also increase mitochondrial biogenesi”
