Short answer: An infrared sauna uses infrared light to warm your body directly, so the air around you stays cooler than in a traditional sauna. At Yaso Wellness on San Antonio's South Side, many people use it to relax and unwind. Studies hint at some possible health effects, but larger, better studies are still needed.
A traditional (Finnish) sauna heats the air with a stove or heated rocks, and the hot air warms you. Some let you pour water on the rocks for bursts of steam.
An infrared sauna uses panels that give off infrared light, which you feel as warmth on your skin. The room air is cooler, so many people can stay comfortable a little longer. You will still sweat a lot.
A steam room, like the one used in a Turkish hammam, uses moist heat at lower temperatures with very high humidity. Each feels different, and people often have a clear favorite.
For many people, the main benefit is simple: time to rest somewhere warm and quiet. Some people say the heat eases sore, stiff muscles after a workout.
Research on longer-term health effects is still early. Sauna use has been studied in heart and blood pressure conditions, dementia, diabetes and arthritis, with some promising signs. But the studies are mostly small or observational, and many used traditional saunas. A sauna should never replace treatment for a medical condition.
Not everyone should use a sauna. Talk with a clinician first, or skip it, if you:
These are signs of heat illness. Heat stroke, when the body can no longer control its temperature, is an emergency. Call 911 for confusion, fainting or a seizure.
Heat can trigger hot flashes in some people in perimenopause or menopause, so the sauna may feel worse, not better, for them. If hot flashes or night sweats bother you, Dr. Vargas can talk through treatment options.
Any weight you lose in a sauna is water from sweating, and it comes back when you drink. For lasting weight change, a medical weight loss program is a better place to start.
What is a far infrared sauna? Infrared light comes in near, mid and far wavelengths. Many home and spa infrared saunas use far infrared heaters. Some "full spectrum" saunas use more than one type.
Does an infrared sauna burn calories like a workout? Your heart rate rises in the heat, but sitting in a sauna is not a substitute for exercise.
Is an infrared sauna safe if I have high blood pressure? Ask a clinician first. Heat changes heart rate and blood pressure, and some blood pressure medicines affect how you handle heat.
Is the infrared light harmful? Infrared heat is not the same as ultraviolet (UV) light from the sun or tanning beds. It warms the skin rather than tanning it.
Looking for a quiet, warm reset? Book an infrared sauna session, and tell staff about any health conditions first.
