The Top 10 Sauna Questions Answered for You
1. Traditional vs. Infrared: What’s the difference?
Traditional Saunas: Use heated rocks and water to create steam, operating at higher temperatures of 165°F - 180°F.
Infrared Saunas: Use light waves to directly heat your body rather than the air, operating at lower temperatures of 120°F - 150°F.
2. How long should a session last?
Optimal Time: 10 to 15 minutes is the standard recommended duration for a traditional sauna session.
Beginners: Start with 5 to 8 minutes to let your body acclimate to the heat.
Infrared: Because the ambient heat is lower, sessions can sometimes last 20 to 30 minutes.
3. What is the ideal temperature?
Traditional: Set between 170°F and 185°F.
Infrared: Set between 120°F and 130°F to start, adjusting up to 140°F as needed.
4. Can you use a sauna every day?
Frequency: Yes, you can use a sauna daily as long as you are healthy and adequately hydrated.
Advice: If you have pre-existing cardiovascular or medical conditions, consult your physician first.
5. Should you sauna before or after a workout?
After Workout: It is best used for post-workout muscle recovery and relaxation. Wait 10–15 minutes post-exercise to let your heart rate drop and body cool down before entering.
6. Do you need to shower before and after?
Before: Yes, a quick rinse removes lotions, perfumes, and sweat, keeping the sauna clean.
After: A cool shower washes away toxins and sweat, helping to lower your core body temperature.
7. Can you bring your phone or electronics inside?
Verdict: Not recommended. High heat and humidity can permanently damage smartphones, batteries, and electronics. Leave devices outside to fully disconnect.
8. What should you wear?
- Attire: Bare skin wrapped in a natural-fiber towel or cotton swimsuit is best. Avoid synthetic materials or jewelry, which can heat up and burn your skin.
9. How much water should you drink?
Hydration: Drink at least 16 to 24 ounces of water before your session, and replenish with another 16 ounces after you finish.
10. Can saunas help with weight loss?
Reality Check: Weight lost during a session is strictly water weight from heavy sweating, which will return once you rehydrate. However, regular use supports overall metabolic recovery and wellness.
