Sauna vs Steam Room: Andrew Huberman Reveals Which He Recommends for Optimal Health

When you're looking to boost your health and recovery, the choice between a sauna and a steam room can seem tough. Both promise relaxation and a range of wellness benefits, but which one truly delivers the results you're after? Neuroscientist Andrew Huberman's insights have sparked fresh interest in how these heat therapies impact your body and mind.

You might wonder if dry heat or steamy air is better for stress relief, muscle recovery, or even sleep. Before you settle into your next sweat session, it's worth understanding what the science—and Huberman—have to say about each option.

Understanding Saunas and Steam Rooms

Saunas and steam rooms both use heat, but they deliver different experiences and physiological effects. Gaining clarity on these distinctions helps when applying insights from Andrew Huberman’s research to your health routine.

Key Differences Between Saunas and Steam Rooms

• Heat Type

Saunas use dry heat generated by wood stoves, electric heaters, or infrared panels, reaching temperatures of 150°F–195°F (65°C–90°C) with humidity under 20%. Steam rooms operate at 110°F–120°F (43°C–49°C) and 100% humidity from steam generators, creating a moist environment.

• Atmospheric Conditions

Saunas maintain low moisture to maximize sweat evaporation, while steam rooms surround you with heavy, damp air, limiting evaporation and increasing perceived heat.

• Material Construction

Saunas feature wood construction that withstands high dry heat and absorbs moisture, preventing discomfort. Steam rooms feature tile, glass, or non-porous materials that resist water accumulation and mold.

• Duration Tolerance

Saunas allow longer sessions, typically 15–20 minutes, due to easier evaporation and temperature regulation. Steam room sessions last about 10–15 minutes because intense humidity speeds up overheating and discomfort.

Common Health Benefits

• Cardiovascular Effects

Saunas and steam rooms both increase heart rate and blood circulation, supporting cardiovascular function. Studies in Finland find regular sauna use links to reduced cardiovascular disease and all-cause mortality (Laukkanen et al., JAMA Intern Med., 2015).

• Muscle Recovery

Heat from either option increases blood flow, which supports removal of metabolic waste and may accelerate muscle recovery after intense exercise.

• Stress Relief

Both environments stimulate heat shock proteins and lower cortisol, which may ease stress based on reports from Huberman and other neuroscientists.

• Respiratory Health

Steam rooms, through humidified air, may provide temporary relief for sinus congestion and airway irritation. Saunas, while less effective for respiratory moisture, also relax airways but don't offer the same acute symptom relief.

Andrew Huberman’s Insights on Heat Therapy

Andrew Huberman, professor of neurobiology at Stanford University, shares research-driven insights on the benefits and optimal use of heat therapy. He discusses how both sauna and steam room sessions influence recovery, brain health, and performance, connecting each method to physiological and neurological effects.

Scientific Perspectives Highlighted by Huberman

Huberman explains that exposure to deliberate heat, like dry or humid environments, increases heart rate and blood flow, supporting cardiovascular health and muscle recovery. He cites studies—such as JAMA Internal Medicine (2015)—showing frequent sauna use (4+ times per week) correlates with lower mortality and reduced cardiovascular risk. He notes heat stress triggers heat shock proteins and increases norepinephrine, both known to accelerate muscle repair and reduce inflammation. For cognitive health, Huberman highlights evidence linking regular sauna use with a decreased risk of neurodegenerative disease, referencing work published in Age and Ageing (2015). He reports that steam rooms provide similar acute cardiovascular and relaxation benefits but references less robust data for long-term health outcomes compared to saunas.

Huberman’s Recommendations and Protocols

Huberman recommends protocols based on the scientific evidence for heat therapy benefits. You can maximize cardiovascular and longevity benefits by using a sauna for 15-20 minutes per session and totaling 57-60 minutes per week, with sessions spread across multiple days, based on current human trials. For muscle recovery, Huberman encourages post-exercise heat sessions to boost circulation and reduce soreness, listing both sauna and steam room as effective for this purpose. He stresses the importance of hydration, advising you to replenish fluids and electrolytes before and after heat exposure. If respiratory relief is a priority, Huberman notes steam rooms can help clear nasal passages and ease congestion, though these effects are generally temporary.

Effects on Physical Health and Recovery

Sauna and steam room sessions create physiological effects that boost recovery and cardiovascular health. According to Huberman, sauna use—citing Finnish longitudinal studies—increases heart rate, promotes vasodilation, and reduces all-cause and cardiovascular mortality (Laukkanen et al., JAMA Intern Med, 2015). Four to seven sessions per week for 15-20 minutes each, totaling about 57-60 minutes, link to optimal benefits. Norepinephrine and heat shock proteins, both elevated during heat exposure, accelerate muscle repair and reduce inflammation. Steam rooms raise core temperature and circulation as well, supporting post-exercise recovery and transiently relieving joint tension. For respiratory relief, steam rooms temporarily alleviate sinus congestion but lack the longevity benefits demonstrated by frequent sauna use.

Impacts on Mental Well-Being and Stress Reduction

Sauna and steam room participation influences mental well-being by modulating stress pathways. Huberman highlights endorphin release, heightened relaxation, and improved mood following deliberate heat exposure. Saunas reduce perceived stress and support better sleep through parasympathetic engagement, with evidence indicating reduced risk for depression (Laukkanen et al., Psychosom Med, 2018) with frequent sessions. Steam rooms offer immediate relaxation and calm the mind, yet studies reveal that sauna practices produce more durable benefits for chronic stress management and mood stabilization. Both methods require consistent routine for noticeable psychological impact.

Choosing What’s Best for You

Sauna and steam room therapies present distinct advantages depending on your goals and personal limitations. Andrew Huberman’s analyses help you match the right method with your needs and routines.

Personal Goals and Preferences

Evaluating personal aims offers clarity in selecting sauna or steam room sessions. For instance, if you’re prioritizing cardiovascular health, sauna sessions—as seen in Finnish cohort studies—align with long-term reduced mortality and heart risk. If acute respiratory relief or sinus congestion is your main concern, steam rooms deliver short-term relief due to higher humidity.

Matching formats to comfort preferences increases your consistency. Dry heat from saunas supports sessions between 15 and 20 minutes, while steam rooms provide intense humidity for users who favor shorter, gentler exposures. If mood stability and chronic stress reduction matter, consistent sauna use yields stronger, durable psychological benefits as highlighted in controlled observational research.

Safety Considerations

Assessing safety factors protects your experience in both sauna and steam room settings. Hydrating before and after exposure is essential since dehydration risk increases with both forms of heat therapy, based on Huberman’s recommendations. If you’re managing cardiovascular conditions or hypertension, confirm with a healthcare provider before engaging in frequent, prolonged heat exposure.

People with respiratory challenges benefit more from steam rooms; however, acute asthma or sensitivity to mold might restrict their use, since these environments often foster dampness. Temperature and exposure duration limits help prevent overheating and faintness. Monitoring personal tolerance avoids negative effects, supporting a safer routine customized to your health profile.
