How Long Should You Stay In The Sauna & Ice Bath?

Physiological Stresses 

Heat and Cold Exposure are two physiological stresses that are intrinsically linked.

But, does the current body of scientific evidence show that they should be done in unison (called: contrast therapy), or are gains realised from both as standalone bouts of stress?

Contrast Therapy vs. Standalone Heat/Cold Exposures

The threshold you're looking to hit weekly for either heat or cold is:

  • at least 11 minutes of uncomfortable but safe cold exposure

  • 57 minutes of sauna (ranging from 86C-100C)

Outcomes: brown fat thermogenesis, increases in resilience, positive dopamine effects, increase human growth hormone and metabolism.

Seeing the benefits from these can happen together as well as in isolation.

Why End On Cold During Contrast Therapy

  • "Post cold exposure your body is going to heat up; think of your body heating up as waking up." - Dr. Andrew Huberman
  • This mirroring of rising naturally boost energy and alertness.
  • Initiates metabolic benefits associated with the Søberg Principle: increased thermogenic processes through naturally re-warming the body
  • Reduces muscle inflammation if done post exercise (within first 24 hours post workout)

Keeping it simple

Too many people are overthink these two protocols.

The overwhelming logic is to do what works best for your routine and, over time, the feedback your own body will tell you what works best.

The main takeaway is aiming for these 11/57 minimums week-in-week-out.
