How Long to Stay in Sauna? Andrew Huberman’s Surprising Answer for Maximum Health Benefits
Curious about the perfect sauna session length for maximum health benefits? You’re not alone. Many wellness enthusiasts look to Dr. Andrew Huberman—a renowned neuroscientist—for science-backed advice on how long to stay in the sauna.
If you want to boost your recovery, improve mental clarity or simply relax, understanding the right timing can make all the difference. Let’s explore what Dr. Huberman recommends so you can get the most from every sweat session.
Understanding Andrew Huberman’s Sauna Recommendations
Andrew Huberman’s sauna guidelines center on specific total weekly heat exposure for measurable health gains. You target 57–60 minutes of sauna use per week, distributed across 2–4 sessions, for the best results (Huberman Lab Podcast, Episode 70). Typical sessions last 12–20 minutes, and you adjust duration based on your heat tolerance.
You separate sauna sessions by adequate cooling-off periods, which enhance temperature adaptation and safety. You space these out, such as pairing 15-minute heat exposures with short, cool-down intervals, for effective cardiovascular and longevity support. Huberman links these sauna routines to reduced all-cause mortality and significant cardiovascular improvement (Laukkanen et al., JAMA Internal Medicine, 2015).
You note that Huberman emphasizes regularity and consistency, not just intensity. You spread out sauna time over several sessions each week, rather than attempting all recommended minutes in one session.
The Science Behind Sauna Use
Sauna use engages physiological responses that impact your cardiovascular, neuromuscular, and neurocognitive systems. Research cited by Andrew Huberman connects sauna exposure to measurable health benefits and specific safety considerations for optimal longevity.
Health Benefits of Sauna Sessions
Regular sauna sessions increase heart rate and blood circulation, promoting cardiovascular health. Studies show you can reduce all-cause mortality and lower risks of hypertension, stroke, and dementia with consistent sauna use—examples include cohorts in Finland with frequent weekly sessions showing up to 40% fewer cardiovascular events (Laukkanen et al., JAMA Intern Med, 2015). Heat exposure triggers heat shock protein production and hormesis, enhancing cellular repair and bolstering immune defenses. Session durations of 12–20 minutes, as recommended by Huberman, support muscle recovery, relaxation, improved sleep quality, and increased endorphin release. Distributing sauna exposure across 2–4 sessions weekly, totaling about 60 minutes, maximizes cumulative benefits.
Potential Risks and Precautions
Sauna use poses risks if you ignore hydration, excessive heat, or contraindications. Prolonged exposure—sessions exceeding 30 minutes, for example—may increase dehydration, hypotension, or syncope in those sensitive to rapid changes in blood pressure (Mero et al., Sports Med, 2015). Avoiding the sauna when pregnant, intoxicated, or dealing with existing cardiac disorders helps prevent adverse events. Cooling-off periods between sessions prevent overheating and support cardiovascular adaptation. If you experience dizziness or nausea, exiting the sauna immediately remains critical. Always consult a healthcare provider before starting a new sauna regimen, especially if you have chronic medical conditions.

Recommended Session Duration and Frequency
Target 57–60 minutes of sauna use per week, according to Dr. Huberman's advice (source: Huberman Lab Podcast, episode on sauna and heat exposure). Divide this time into 2–4 sessions. Each session lasts 12–20 minutes for most users. Prioritize regularity over high intensity. Allow cooling-off periods of similar length between sessions for safety and thermal adaptation. Typical protocols use 180–195°F (82–90°C) as the recommended sauna temperature.
| Total Weekly Minutes | Sessions per Week | Session Length | Recommended Temperature |
|---|---|---|---|
| 57–60 | 2–4 | 12–20 min | 180–195°F (82–90°C) |
Factors That Influence Optimal Sauna Time
Several variables modify your optimal sauna time based on Dr. Huberman's protocols:
- Hydration status: Enter the sauna hydrated, since dehydration increases cardiovascular risk, particularly over 20 minutes.
- Health conditions: Check with a medical provider before using a sauna if you've got heart disease, low blood pressure, or pregnancy.
- Adaptation level: Beginners use shorter sessions (around 10 minutes), while experienced users may reach 20 minutes as tolerance improves.
- Age and medication: Older adults and those on specific medications (for blood pressure or diuretics) may require shorter durations due to altered thermoregulation.
Huberman emphasizes that regular, moderate sessions support cardiovascular and neurocognitive health and lower all-cause mortality rates, as supported by peer-reviewed sauna research.
Tips for Safe and Effective Sauna Use
Follow guidelines for session length and frequency to maximize sauna benefits and minimize risks. Limit individual sessions to 12–20 minutes, mirroring protocols discussed by Dr. Andrew Huberman across neuroscience and longevity research. Space sessions throughout the week to reach a 57–60 minute total, with 2–4 sessions per week supporting cardiovascular and neurocognitive gains.
Hydrate thoroughly before, during, and after sauna exposure to prevent dehydration, a leading risk during heat therapy. Choose water and include electrolytes if sessions exceed 15 minutes or if sauna use follows intense exercise.
Cool down completely between or after sessions to assist cardiovascular recovery and enhance heat adaptation. Use cold showers, ambient air breaks, or gradual cooling, as peer-reviewed sports science recommends, to restore normal heart rate and body temperature.
Listen to body signals and exit the sauna if you experience dizziness, headache, nausea, or irregular heartbeat. These warning signs often indicate overheating or blood pressure shifts and require immediate attention.
Avoid sauna sessions if you have contraindicated conditions such as pregnancy, unstable cardiac disorders, or certain medication regimens—always consult your healthcare provider before beginning or adjusting your sauna routine.
Maintain clean humidity and ventilation in sauna spaces to reduce respiratory and dermatological irritation. Ventilate rooms after each use and clean surfaces regularly for optimal hygiene.
Wear minimal, breathable clothing—such as a towel or swimsuit—so heat can evenly access the skin, which accelerates sweat response and effective cooling.
Schedule sessions consistently to establish adaptation and derive lasting health rewards. Prioritize weekly consistency over intensity, as highlighted by Huberman, for sustainable benefits in stress reduction and temperature regulation.
