Follow these science-backed steps to maximize your results.

1

Brown Fat Activation Cold water hitting your upper back and neck activates brown fat, which burns calories to generate heat and keep your core temperature stable.
2

Norepinephrine Spike The shock of cold water causes a massive release of norepinephrine, a hormone that helps break down fat cells for energy.
3

Improved Circulation Cold water causes blood vessels to constrict and then dilate, improving circulation and helping your body move nutrients and waste more efficiently.
