Dr. Rhonda Patrick didn't just popularize sauna science—she pioneered it. Years before sauna bathing became a mainstream wellness trend, Patrick was diving into Finnish cardiovascular studies, heat shock protein research, and the molecular mechanisms connecting heat exposure to longevity.
As a biomedical scientist with a PhD from the University of Tennessee Health Science Center and postdoctoral training at St. Jude Children's Research Hospital and the Salk Institute, Patrick brings a rigor to wellness recommendations that few can match. Her sauna protocols are built on peer-reviewed research, not trends.
Who Is Dr. Rhonda Patrick?
Rhonda Patrick, PhD, is a biomedical scientist specializing in aging, cancer, and nutrition. She holds a Bachelor's degree in biochemistry/chemistry from the University of California, San Diego, and completed her doctoral work in biomedical science at the University of Tennessee Health Science Center.
Her postdoctoral research focused on the role of insulin signaling in brain health, specifically studying links between metabolism and neurodegeneration at prestigious institutions including the Salk Institute for Biological Studies.
In 2012, Patrick founded FoundMyFitness, which has grown into one of the most respected platforms for science-based health information. Her appearances on the Joe Rogan Experience podcast (episodes #502, #568, #672, #901, and more) introduced millions to the research behind sauna use and longevity. She has also published peer-reviewed research, including a comprehensive 2021 review article in Experimental Gerontology titled "Sauna use as a lifestyle practice to extend healthspan."
The Science Rhonda Patrick Cites
The Finnish Sauna Studies
The foundation of Patrick's sauna recommendations comes from the Kuopio Ischemic Heart Disease Risk Factor Study—a prospective, population-based cohort study tracking over 2,300 middle-aged Finnish men for more than 20 years. This landmark research, led by Dr. Jari Laukkanen, revealed striking dose-response relationships between sauna use and mortality. For context on how these parameters translate to home use, see our sauna duration guide.
| Sauna Frequency | Risk Reduction vs 1x/Week |
|---|---|
| 2-3 times per week | 22% lower sudden cardiac death, 24% lower all-cause mortality |
| 4-7 times per week | 63% lower sudden cardiac death, 40% lower all-cause mortality |
| >19 minutes per session | 50% reduction in cardiac death vs <11 minutes |
The study also found sauna use was inversely associated with dementia and Alzheimer's disease—men using sauna 4-7 times weekly had a 66% reduced risk of dementia compared to once-weekly users. These findings were published in JAMA Internal Medicine and Age and Ageing, respectively.
Heat Shock Proteins (HSPs)
Patrick considers heat shock proteins "one of the most robust molecular mechanisms" activated by sauna use. HSPs are a class of proteins produced in response to stressful conditions—including heat exposure—that serve critical protective functions:
🧬 Why Heat Shock Proteins Matter
- Protein Chaperoning: HSPs help maintain the three-dimensional structure of other proteins, preventing misfolding and aggregation. This is crucial because protein aggregation underlies neurodegenerative diseases like Alzheimer's (amyloid-beta plaques) and Parkinson's.
- Cellular Repair: When proteins become damaged by reactive oxygen species or other stressors, HSPs can repair them, restoring proper function and extending protein half-life.
- Muscle Preservation: HSPs help prevent muscle atrophy by protecting muscle proteins from degradation. Studies in rats showed 30% more muscle regrowth when HSPs were elevated through heat exposure.
- Longevity Connection: The HSP70 gene variant has been linked to increased human longevity—individuals with one copy live approximately one year longer, while those with two copies may live two years longer than those without.
FOXO3 Gene Activation
Beyond HSPs, Patrick highlights how heat stress activates the FOXO3 gene—a longevity-associated gene that humans with certain polymorphisms are significantly more likely to become centenarians. FOXO3 promotes cellular resilience, DNA repair, and protects against oxidative damage. Mice genetically engineered to produce more FOXO3 show 30% increases in lifespan.
Cardiovascular Mechanisms
Patrick emphasizes that sauna use mimics moderate cardiovascular exercise. During a sauna session your heart rate increases to 120-150 BPM, cardiac output increases as blood flow redirects to the skin, blood vessels dilate improving endothelial function, and afterward blood pressure and resting heart rate drop below baseline.

Rhonda Patrick's Sauna Protocol
Based on her extensive review of the literature and personal practice, Patrick recommends the following protocol:
| Parameter | Patrick's Recommendation |
|---|---|
| Temperature | 174°F+ (79°C+) — ideally 80-100°C (176-212°F) |
| Duration | 20 minutes minimum per session (Patrick personally does ~30 minutes) |
| Frequency | 4-7 times per week for optimal benefits |
| Sauna Type | Traditional Finnish (dry) sauna preferred |
| Post-Sauna | Cold shower or cold plunge for contrast therapy |
🔥 Patrick's Personal Practice
In interviews, Patrick has shared that her own sauna is set to approximately 175°F (79°C) and she aims for 30-minute sessions. She emphasizes that 20 minutes appears to be the minimum threshold for cardiovascular benefits based on the Finnish research.
Saunas for Patrick's Protocol

View Product →Traditional vs Infrared: Rhonda's Perspective
Patrick has been clear about her preference for traditional Finnish saunas, and her reasoning is grounded in the research. For a detailed comparison, see our infrared vs traditional sauna guide.
🌡️ Temperature Matters
The Finnish studies showing longevity benefits used traditional saunas operating at approximately 79°C (174°F). Infrared saunas typically operate at 60-65°C (140-150°F). While infrared saunas can still offer benefits, Patrick notes you may need longer sessions to achieve equivalent effects.
📊 Research Disparity
The bulk of the cardiovascular and longevity research has been conducted on traditional Finnish saunas. Research on infrared saunas (sometimes called "Waon therapy" in clinical literature) exists but is more limited in scope and scale.
✅ Infrared Has Its Place
Patrick acknowledges that infrared saunas show benefits for specific conditions. Research demonstrates infrared sauna use can increase blood vessel density in aged muscles by 33% and may improve symptoms in chronic heart failure patients. For muscle preservation and certain therapeutic applications, infrared can be effective—you just need to stay in longer.
Infrared Options for Extended Sessions
If traditional isn't an option, these full-spectrum infrared saunas can still deliver benefits with longer session times:

View Product →Sauna + Cold: Does Rhonda Combine Them?
Yes—and she points to Finnish tradition as validation. Contrast therapy (alternating between heat and cold) is a standard practice in Finland, where cold water plunges or rolling in snow often follow sauna sessions.
Patrick notes that research suggests cold water immersion after sauna use provides all the same benefits as regular sauna bathing—the contrast doesn't diminish the heat exposure benefits. The cold exposure adds its own benefits, including norepinephrine release (200-300% increase), cold shock protein activation linked to synaptic regeneration, cardiovascular stimulation, and enhanced mood with reduced inflammation.
Safety Considerations Rhonda Emphasizes
For complete safety guidance, see our sauna safety guide.
💧 Hydration
Patrick stresses that proper hydration is non-negotiable. Sauna sessions cause significant fluid loss through sweating, and dehydration can negate benefits and create health risks. Drink water before, during (if possible), and after sessions. She also recommends replenishing electrolytes—sodium, potassium, and magnesium—especially after longer or more frequent sessions.
Never combine sauna use with alcohol. Alcohol impairs your body's thermoregulatory mechanisms, increases dehydration risk, and can mask warning signs of overheating. This is a serious safety concern Patrick emphasizes repeatedly.
While higher temperatures may provide greater benefits, Patrick warns about exceeding 200°F (93°C). At extreme temperatures, the risks of overheating increase significantly. Start at lower temperatures and gradually increase as your body adapts.
🚫 Who Should Avoid or Modify
- Pregnant women (avoid sauna entirely)
- People with cardiovascular conditions (consult physician first)
- Those with uncontrolled hypertension
- Individuals on medications affecting blood pressure or hydration (beta-blockers, diuretics)
- Anyone who feels dizzy, lightheaded, or unwell during sessions (exit immediately)
Frequently Asked Questions
Patrick uses a traditional dry sauna set to approximately 175°F (79°C). She has emphasized that the type of sauna matters less than reaching adequate temperature and duration—traditional Finnish saunas are preferred because they can reach the temperatures used in the longevity research (174°F+).
Patrick recommends 4-7 times per week based on the Finnish research showing dose-dependent benefits. The 40% reduction in all-cause mortality was observed in men using sauna 4-7 times weekly. She personally aims for frequent use, typically 30-minute sessions.
Patrick prefers traditional saunas because the longevity research used Finnish-style saunas at 174°F+. However, she acknowledges infrared saunas have benefits—they just operate at lower temperatures (around 140°F), so you may need longer or more frequent sessions. Infrared research shows benefits for heart failure symptoms and muscle blood vessel density. See our infrared vs traditional comparison for more details.
Patrick suggests using the sauna after exercise. Post-workout sauna use can enhance the growth hormone response from training, protect against free radical damage generated during exercise, and aid muscle recovery. The heat shock proteins activated by sauna use help preserve muscle and promote repair. See our sauna timing guide for detailed recommendations.
Heat shock proteins are molecular chaperones produced in response to heat stress. They maintain proper protein folding, prevent protein aggregation (which underlies diseases like Alzheimer's), and help repair damaged proteins. The HSP70 gene variant is associated with increased human longevity. Sauna use reliably increases HSP production—a 30-minute session at 163°F boosts HSP levels about 50% above baseline.
FOXO3 is a longevity-associated gene—people with certain FOXO3 polymorphisms are significantly more likely to become centenarians. The gene promotes cellular resilience, DNA repair, and protection against oxidative damage. Heat stress from sauna use activates FOXO3, which may explain part of the longevity connection observed in the Finnish studies.
Patrick recommends a minimum of 20 minutes per session to achieve cardiovascular benefits based on the Finnish research. She personally does approximately 30-minute sessions. The Finnish study showed that sessions longer than 19 minutes had a 50% reduction in cardiac death compared to sessions under 11 minutes. For more on optimal duration, see our sauna duration guide.
No—Patrick notes that research suggests cold water immersion after sauna use provides all the same benefits as regular sauna bathing. The contrast doesn't diminish the heat exposure benefits, and the cold exposure adds its own benefits including norepinephrine release (200-300% increase), cold shock protein activation, and enhanced mood. She recommends following sauna with a cold shower or plunge.
