How Long Should You Stay in an Infrared Sauna?

Finding the right balance in an infrared sauna is key to safety and benefits. This guide covers recommended session lengths, temperature factors, and essential hydration tips.

Session Time Trends by Heat Level

Higher heat generally calls for shorter sessions, even for experienced users.

Determining how long to stay in an infrared sauna depends on your experience level, health status, and personal tolerance. Unlike traditional saunas that use high ambient heat, infrared saunas use light to warm the body directly, often allowing for longer, more comfortable sessions while still promoting a deep sweat.

Beginner Session Guidelines

If you are new to infrared therapy, it is best to start here with shorter durations. Beginners should aim for 10 to 15 minutes at a moderate temperature. This allows your body to acclimate to the heat without overexertion. As you become accustomed to the experience, you can gradually increase your time by 5-minute increments.

Guidelines for Regular Users

Once comfortable, most regular users find that 25 to 45 minutes is the ideal duration for maximizing infrared sauna benefits. While some experienced users may stay in longer, sessions exceeding 60 minutes are generally unnecessary and significantly increase the risk of dehydration and electrolyte imbalance.

Temperature and Timing

Infrared saunas typically operate between 110°F and 150°F (43°C to 65°C). Lower temperatures allow for longer sessions, while higher settings may require you to exit sooner. Always prioritize how your body feels over the time remaining on the clock.

Sauna Safety and Hydration

Maintaining sauna safety requires proactive hydration. Drink at least 8–16 ounces of water before entering and continue sipping water or an electrolyte-rich beverage throughout your session. If you feel dizzy, lightheaded, or nauseous, exit the sauna immediately and cool down.

Post-Sauna Recovery

After your session, allow your body to cool down naturally for 10–15 minutes before taking a shower. Incorporating these steps into your sauna routines and recovery helps stabilize your core temperature and heart rate. Proper sauna maintenance, such as wiping down benches, also ensures a hygienic environment for your next session.

When to Consult a Professional

Before starting a new heat therapy regimen, consult a healthcare provider, especially if you have cardiovascular issues, are taking medication, or are pregnant. Please review our medical disclaimer for more information regarding health-related concerns.
