Precautions for a Sauna

Saunas are used for a number of reasons, including increasing circulation, relaxing and flushing toxins from the body through the skin. While they are generally safe to use, some precautions should be taken to prevent nausea and fainting. Those with certain diseases or conditions should avoid using the sauna.

  1. Who Shouldn't Use a Sauna

    • Do not use a sauna if you have multiple sclerosis, hemophilia or systemic lupus erythematosus. If you have a history of hyperthyroidism or adrenal suppression, meaning the body does not respond to heat, refrain from sauna usage. Do not use a sauna if you are pregnant or nursing, have acute joint injuries, enclosed infections in the joints, tissues or dental area and have implants such as metal pins, breast implants or artificial joints. If you are taking a prescription drug, consult your physician for any potential change in the drug's effect from infrared energy. Do not use a sauna while menstruating as it can increase menstrual flow. If you are heat-intolerant or do not sweat, even during vigorous physical activity, do not use a sauna. Do not drink alcohol prior to using a sauna as the depressant nature of alcohol counteracts the sauna's benefits. Children under 5 also should not use saunas.

    Items to Remove

    • Remove jewelry and glasses before entering the sauna as metal becomes very hot at high temperatures and can cause the skin and capillaries to swell, making bracelets, rings and necklaces tighter. Contact lenses can dry out in a sauna, so remove them. Also, do not bring bottles, cups or glassware into the sauna.

    Additional Precautions

    • Avoid eating before entering a sauna a sweat bathing strains the circulatory system. Wait one to two hours after a meal to use a sauna. In contrast, a completely empty stomach can deplete the system and therefore sweat bathing can cause nausea or fainting. Do not use a sauna if you are extremely tired, have an illness or are recovering from one.

      Try bathing for shorter periods in reduced heat settings. Learn your sauna limits by starting with lower temperatures and gradually building up to higher settings. While the body adapts to repeated heat exposure, it is still a good idea to listen to your body and leave the sauna at the proper time. If you are not used to severe heat, you might experience fainting or nausea, nose bleeds or blood vessel injury. Saunas that are poorly ventilated also can cause nausea. Leave the sauna if you feel nauseous and have a friend or staff member bring you some fruit juice. The natural sugar will help you feel better, according to Sauna Precautions by Mikkel Aaland. Do not stand up quickly after time in a sauna, which can cause the blood to rush down your body and away from your head.
