Are infrared saunas good

Yes—infrared saunas may be beneficial, particularly for heat-related cardiovascular effects, but they’re not necessarily equivalent to hotter traditional saunas and they don’t replace exercise.

• 1. Temperature and duration: Infrared saunas often reach only about 140°F, while many sauna studies used about 174°F. A longer exposure may be needed; one infrared protocol discussed involved staying warm for roughly an hour. 1
• 2. Heat-related effects: Sauna heat raises heart rate, and studies described improvements in resting heart rate and blood pressure after exposure. Heat stress also activates heat-shock proteins. 2 3
• 3. Infrared light is distinct: Benefits attributed to infrared or red-light exposure are separate from benefits associated with getting hot; the discussed sauna benefits primarily relate to heat stress. 4
• 4. Safety: Seek medical advice before sauna use after a recent heart attack or with an uncommon heart condition; older adults prone to low blood pressure should also consult a physician. Pregnancy is another reason to avoid sauna exposure or get medical guidance. 5
