Infrared saunas operate differently than traditional steam saunas by using radiant heat to warm the body directly rather than heating the air around you. For those new to this technology, finding the right balance between comfort and effectiveness is key to a positive experience. Before beginning any new heat therapy, please review our medical disclaimer to ensure it is appropriate for your health status.
The Ideal Starting Temperature Range
For your first few sessions, the recommended temperature range is 110°F to 120°F (43°C to 49°C). While many infrared saunas can reach 150°F, starting at the lower end allows your cardiovascular system to adapt to the radiant heat without undue stress.

Why Lower is Better Initially
Because infrared waves penetrate the skin deeply, you may begin to sweat at lower air temperatures than you would in a dry Finnish sauna. Starting low helps you gauge your tolerance and prevents early fatigue or lightheadedness.
How to Progress Safely
Once you feel comfortable at 120°F for a full 15 to 20-minute session, you can begin to increase the heat. A safe progression involves increasing the temperature by 5°F every two or three sessions. Most regular users eventually find their "sweet spot" between 130°F and 140°F. Prioritizing sauna safety means listening to your body rather than chasing a specific number on the thermostat.
What to Expect During Your First Session
In an infrared cabin, you might not start sweating immediately. It often takes 10 to 15 minutes for the core body temperature to rise sufficiently to trigger a sweat response. This delay is normal. Even at lower temperatures, you may still experience infrared sauna benefits such as relaxation and temporary relief from muscle soreness.
Sweating Expectations
Do not be discouraged if you do not sweat profusely during your first session. Your body's thermoregulation system becomes more efficient with regular use. Focus on staying hydrated before, during, and after your session.
Signs You Should End the Session
Regardless of the temperature setting, you should exit the sauna immediately if you experience any of the following:
- Dizziness or lightheadedness
- Nausea
- A rapid, pounding heartbeat
- A sudden feeling of being chilled
- Extreme fatigue
Safety is the most important factor in establishing long-term sauna routines and recovery habits.
Frequently Asked Questions
How long should a beginner stay in an infrared sauna?
Beginners should aim for 10 to 15 minutes. As you become accustomed to the heat, you can gradually extend this to 20 or 30 minutes.
Should I preheat the sauna?
Yes, preheating for 15 to 20 minutes ensures the emitters are active and the cabin is at your desired starting temperature when you enter.
Can I use the sauna every day?
While many people do, beginners should start with 2 to 3 sessions per week to see how their body responds before increasing frequency.
