The Truth About Cold Therapies

Dr. Rhonda Patrick, Ph.D. has produced an in-depth research report that takes a deep dive into the physiological effects of cold therapies, including cryotherapy.  Here are some of her findings related to cryotherapy:

  • Cold exposure increases norepinephrine up to 5-fold in the brain.
  • Norepinephrine has an effect on mood, increases vigilance, focus, and attention (especially over a prolonged period).
  • Cold exposure increases cold shock proteins, which repairs damaged synapses in the brain and in prevents muscle atrophy.
  • Cold-induced norepinephrine lowers inflammation and pain by decreasing the levels of three inflammatory mediators.
  • Chronic cold shock may increase immune cell numbers.   
  • Cold exposure increases metabolic rate, the number of mitochondria, and the burning of fat.  
  • The effects of different cold exposure temperatures and timing on athletic performance, recovery time, and muscle mass.
  • Cold shock is a type of hormesis, which is a description of a type of stress that, in the right doses, is enough to shock the body and kick off adaptive processes and response mechanisms that are hardwired into our genes, and, once on, are able to create a resilience that actually exceeds what was needed to counter the initial stimuli.
