When you’re exposed to cold, your body increases production of norepinephrine in the brain, which is involved in focus and attention. It also improves mood and alleviates pain because it lowers inflammation. Inflammation is the leading cause to pretty much every dis-ease in our country. Short bursts of good stress are proving to be beneficial to overall health ie. extreme cold/heat and HIIT exercise.

Here is what the Drs. are saying:

“Modern life has a deficiency of stimulating factors such as cold, heat and physical stress and this results in poor resistance to disease” -Dr Siems.

One of the main reasons why short bursts of stress are so good for you, because we have so many amazing genes in our body that are so powerful. We need to find ways to activate them more …” Dr. Rhonda Patrick


  • Reduces Pain and Inflammation
  • Increases Blood Circulation through vasoconstriction and vasodilation.
  • Detoxes and Boosts the Immune System
  • Increases Dopamine and Lowers Cortisol
  • Quicker Recovery Time from Surgery
  • Boosts Metabolism by increasing brown fat

Cold exposure aids in the production of mitochondria to increase and activate brown fat.

Brown Fat– Its primary function is thermoregulation. Mitochondria packs into white fat and feeds on the stored up calories producing energy and releasing heat as a by product.

“The more mitochondria you have in your fat, the more fat you’re burning.”– Dr. Rhonda Patrick
