FAQs
Can Your Sauna Duration Change Based on the Type of Sauna (e.g., Infrared vs. Traditional)?
The duration in a sauna depends on the type. Infrared saunas (120-150°F) are safe for 30-45 minutes, while traditional saunas (150-195°F) are best for 15-20 minutes due to their higher intensity. Infrared saunas penetrate deeper for muscle recovery, while traditional saunas use heat and humidity, making the air feel heavier. Always listen to your body.
Does Timing Your Sauna Session Post-Workout Affect Its Benefits?
Wait 10–15 minutes after exercise to let your heart rate stabilize before using the sauna. Aim for a 15–20 minute session within 30–60 minutes post-workout to reduce soreness, improve circulation, and aid muscle recovery.
Can You Split a Long Sauna Session into Intervals for More Safety?
Breaking up your sauna session into intervals helps prevent overheating and reduces strain on your heart. Resting for 5-10 minutes between intervals lowers the risk of heatstroke and allows your body to recover.
Does Your Hydration Level Affect How Long You Can Stay in a Sauna?
Hydration is key to safely staying in a sauna. Drink 16-20 ounces of water 30 minutes before entering. Proper hydration helps your body regulate temperature and sweat, reducing the risk of heat exhaustion. If dehydrated, sweating becomes harder, and you may feel lightheaded. When well-hydrated, you can typically stay 15-20 minutes, but always listen to your body for discomfort.
