I have looked through quesion library and can not find anything from Dr. Weil on Infared sauna's. I'm thinking of getting one and would like to know if Dr.Weil believes it is benificial for detoxifying, weight loss, high blood pressure etc. Also, is there any possible bad side effects from using the sauna for 30mins/3 times a week. Any info would be appreciated!

 Hello

Dr. Weil says

Far-infrared saunas are a variation on the theme. Instead of a stove, a special heater generates infrared radiation, said to warm the body in the same way as sunlight. In fact, I understand that the infrared radiation warms the body rather than the surrounding air. I haven't tried a far-infrared sauna so I can't say whether the experience is any better than a traditional one. (Sauna purists say that infrared is not as invigorating or relaxing.) Some proponents say you can sweat three times more than in a traditional sauna or steam room and claim that the "deep penetration" of the infrared heat stimulates greater release of "stored fats and toxins." I've also seen claims that a session in a far-infrared sauna is the equivalent of the cardiovascular workout you would get from running 10 to 15 kilometers. I'm skeptical of that. (Remember that any weight you lose in a sauna will come right back once you replace the fluids that you've sweated out.)

I prefer a sauna in which heat comes from heated rocks, allowing you to put water on the rocks to create steam, because I find that the dry air of electric saunas irritates my upper respiratory tract. I'm unaware of any specific dangers of far-infrared saunas, but I would caution you to go easy on any type of sweat-inducing heat (sauna or steam bath) if you have high blood pressure or heart problems. The main risk of either a sauna or steam bath is overdoing it - you can faint from overheating. Be sure to drink plenty of water, before, during and after your sauna (or steam bath). And be sure to limit the time you spend in the heat - 10 to 20 minutes is usually enough.

Andrew Weil, M.D.
