Using dry saunas as a form of heat therapy originated in Finland centuries ago, and it is still used today as an alternative therapy for relieving stress, tension and for overall wellness. In moderation, sauna bathing is generally recognized as safe for healthy people, according to the National Institutes of Health and the American Heart Association. People suffering from any kind of disease affecting the circulatory system or skin should first consult their doctor before beginning a dry sauna therapy regimen.
Lowered Blood Pressure
The dry heat provided by a sauna bath can help to lower blood pressure in people suffering from hypertension, or high blood pressure, according to a Finnish study published by the National Institutes of Health. Furthermore, the American Heart Association says that dry saunas can have the same effect on blood pressure that a brisk walk can have, although they are quick to point out that soaking in a sauna is no replacement for a consistent exercise regimen.
Asthma and Bronchitis Relief
A Finnish study cited by the National Institutes of Health suggests that the improvements in pulmonary function that occur during a sauna bath may provide relief to those suffering from asthma, bronchitis and other similar respiratory diseases.
Joint and Muscle Pain Relief
Dry heat therapy seems to have a positive effect on those with joint and muscle pain, such as those suffering from fibromyalgia. A type of alternative therapy called Waon therapy has been used to treat fibromyalgia patients. Waon therapy involves soaking in a dry sauna for a period of time, and then moving into a warm room and being wrapped in blankets. This type of dry sauna therapy has been shown to reduce pain in those suffering from fibromyalgia, according to University of Maryland Medical Center.
Healthier Skin
Dry heat has a positive effect on skin, and with moderate exposure may even provide some relief to those suffering from psoriasis. Sweating caused by exposure to the dry heat of a sauna tends to open the pores of the skin, which cleanses the outer skin and removes salts from the body, according to Columbia University's Go Ask Alice! health website.
Increased Blood Circulation
As the body is exposed to the high heat of a sauna, the blood vessels expand and become more flexible, which allows for increased blood circulation throughout the body. This can help to relax the body and is the reason many people find dry saunas to be an effective form of stress and tension relief.
