Infrared sauna FAQ

How hot should an infrared sauna be?

Infrared saunas typically run 110-150°F (43-65°C), much cooler than traditional saunas because infrared heats your body directly rather than the air.

How long should you stay in an infrared sauna?

10 to 40 minutes depending on experience and goal. Beginners should start with 10-15 minutes and build up gradually while staying well hydrated.

How often should you use an infrared sauna?

3 to 4 sessions per week is a common target, though some heart-health studies used 4 or more. Consistency over weeks matters more than any single long session.

Is infrared sauna use safe?

Generally safe for healthy adults, but drink water before and after, and avoid it if you are pregnant, have low blood pressure, or a heart condition without medical clearance. Step out if you feel dizzy.
