Saunas and steam baths provide many benefits by using heat to treat aches, pains and even some illnesses. The primary difference between a steam bath and a sauna is that saunas typically provide dry heat, while a steam bath provides heat plus moisture. The heat in a sauna can get quite high--sometimes as high as 175 degrees F--and should be used cautiously by beginners. In general, you should drink a glass of water before getting into the sauna and then shower and drink additional water once the sauna time is completed. Beginners should spend no more than 10 minutes in a sauna or steam bath, working up to 20 minutes.
Relieve Muscle Tension
Relaxation tops the list of sauna and steam bath benefits because the heat causes tight muscles to loosen. The North American Sauna Society says this happens because the high heat of the sauna sends the heart rate racing. This sends endorphins into the blood, similar to a runner's high. Additionally, blood circulating around and through tight muscles also causes them to feel rejuvenated. Any oxygen that is delivered to sore or overused muscles also helps to repair small tears or inflammation.
Help Clear Congestion
Physicians at the Mayo Clinic recommend humidity to help clear nasal passages during a cold. Those doctors say cold viruses thrive in dry air. Keeping your nasal passages moist with regular steam baths may help keep cold viruses from taking hold in dry winter months. You can turn your bathroom into a steam room by closing the doors and running the hot water for several minutes, creating steam. If your congestion is accompanied by a fever, though, skip the steam bath, stay home and drink plenty of fluids. Always check with your personal physician before beginning any treatment program.
Removes Toxins
Calcium or lactic acid deposits may stiffen muscles after a vigorous workout. The report "Differential effects of sauna-, diuretic-, and exercise-induced hypohydration," published through PubMed.gov, shows that a sauna can decrease the amount of lactic acid. This helps remove those toxins from the muscles by sweating them out. The heat helps open your pores, allowing the body to sweat out calcium, lactic acid and other toxins. Additionally, you'll sweat out electrolytes, so consider replacing them with a sports drink and a cup or two of water following the sauna or steam bath.
