Cold and heat exposure have shown effects on hormone health, metabolism, and neurotransmitters like dopamine and epinephrine.

“because the thermogenic effects are all downstream of epinephrine (adrenaline) release.”

“When you go into cold water, that too is a stressor and you liberate adrenaline in response to cold water. So, if you get into an ice bath or a cold shower, you will immediately release adrenaline from your adrenals.”

“Cold causes the release of adrenaline from your adrenals. And it causes the release of epinephrin from these neurons that connect to fat.”

“Cold causes the release of adrenaline from your adrenals. And it causes the release of epinephrin from these neurons that connect to fat. Now, the big effects of cold on metabolism and fat burning are going to be through two routes. One, is that if you expose yourself to cold, you have the opportunity to trigger activation of brown fat as well as to convert more beige fat into true brown fat.”

“And throwing your body into a cold tub, an ice bath, or whatever it may be certainly is going to have a physiological stress response.”

“And what is also inevitable is that when you get into the cold, you will experience a surge in epinephrine and norepinephrine.”

“adding to a long and important history of research focusing on the role of cold and the role of heat in altering various aspects of the body's physiology including Hormone Health metabolism and changes in neurotransmitters such as dopamine and epinephrine”

“Cold causes the release of adrenaline from your adrenals and it causes the release of epinephrine from these neurons that connect to fat. The paper published in Nature shows that it is shivering itself that causes the brown fat to increase your burning, your burn rate, and your metabolism.”
