The Science behind Sauna and Cold Exposure

TLDRSauna and cold exposure have numerous benefits such as increasing brown fat thermogenesis, resilience, dopamine levels, and growth hormone release. The recommended minimum amount of uncomfortable but safe cold exposure per week is 11 minutes. The combination of heat and cold can be done in cycles or separately, depending on individual goals. Sauna and cold exposure protocols can be optimized to achieve specific outcomes such as reducing inflammation or increasing growth hormone levels. Ending on cold exposure can have a thermogenic metabolic response. Different facilities and methods can be used to incorporate sauna and cold exposure into one's routine, even if access to a sauna is limited.

Q&A

What are the recommended temperature ranges for heat and cold exposure?

Heat exposure is generally between 187-212 degrees Fahrenheit, while cold exposure should be cold enough to be uncomfortable but safe.

What are the benefits of ending a session on cold exposure?

Ending on cold exposure can have a thermogenic metabolic response and stimulate the body to heat up naturally, which can be beneficial for those concerned about sleep.

Can sauna and cold exposure be combined?

Yes, sauna and cold exposure can be combined in cycles or done separately based on individual goals and preferences.

Can sauna and cold exposure be done in one day?

Yes, sauna and cold exposure protocols can be customized to fit one's schedule, whether it is done in one day or spread out throughout the week.

What are the potential risks associated with sauna and cold exposure?

Heat exposure should be done with caution to avoid overheating, dehydration, and electrolyte imbalances. Cold exposure should be safe and uncomfortable but not to the point of causing harm.
