Dr. Rhonda Patrick has become one of the most cited voices on sauna research in the performance and longevity community. Her interviews on the Joe Rogan Experience and her own FoundMyFitness platform have brought the Finnish epidemiological data and the mechanistic science of sauna to millions of people who might otherwise never encounter academic research. Understanding her specific recommendations and the research she cites helps athletes apply sauna practice with precision rather than approximation.
Patrick's Core Sauna Recommendations
Based on her analysis of the Finnish research and the mechanistic studies, Rhonda Patrick's general recommendations for sauna use are:
Temperature: 80 to 100 degrees Celsius (176 to 212 degrees Fahrenheit) for traditional Finnish sauna. Lower temperatures produce less dramatic physiological response.
Duration: 15 to 20 minutes per session. The Finnish mortality data shows the strongest protective associations at this duration. Longer sessions don't necessarily produce proportionally greater benefit and increase dehydration risk.
Frequency: The Finnish data shows dose-dependent associations — 4 to 7 sessions per week produced the greatest risk reduction. Two to three sessions per week produced intermediate benefit. For most people, 3 to 4 sessions per week represents the practical optimum of benefit versus time commitment.
Timing relative to exercise: Post-exercise sauna for most applications. Pre-sleep sauna for people using it specifically for sleep improvement — the body temperature drop after sauna facilitates sleep onset.
Patrick on Growth Hormone
Patrick has specifically highlighted the growth hormone research, noting that sauna use can produce growth hormone elevations of 200 to 1600% above baseline depending on protocol. She cites research showing that two 20-minute sauna sessions at 80 degrees Celsius separated by a 30-minute cooling period produced 5-fold growth hormone elevation in healthy adults.
She connects this to both athletic recovery (growth hormone drives muscle protein synthesis and tissue repair) and longevity (growth hormone declines with age and its maintenance is associated with better aging trajectories). For athletes, this growth hormone elevation from sauna is additive to the GH response from training.
Patrick on BDNF and Cognitive Performance
She has highlighted the BDNF-elevating effects of both exercise and heat stress, noting that the combination produces greater elevation than either alone. Her framing: physical practices that produce BDNF are investments in cognitive longevity as well as current performance. The dementia risk reduction data she consistently references supports this framing with epidemiological weight.
The Post-Sauna Protocol Patrick Describes
Patrick's described post-sauna protocol involves cooling (often cold shower or cold plunge) followed by rest and rehydration. She emphasizes the importance of allowing complete cooling before the next sauna round rather than rushing back in while still elevated in temperature.
The skin care dimension she doesn't address — but which is the natural completion of her protocol — is what to use in the post-sauna shower. The open-pore state she describes from heat exposure is the optimal window for natural soap delivery of active botanical compounds. Our Activated Charcoal Black Bar Soap in this window delivers on the cellular-level cleaning opportunity that the sauna creates.
