Health Risks and Benefits
Saunas can be dangerous due to the risk of heat prostration or the even more serious hyperthermia. Children and older persons who have heart disease or seizure disorders or those who use alcohol or cocaine are especially vulnerable.
Prolonged stay in a sauna may lead to the loss of electrolytes from the body, the same as after rigorous exercise. Risks of dehydration leading to heat stroke in more sensitive individuals can occur and may be reduced by regular sipping of water or isotonic drinks, but not alcohol, during the sauna. Sauna bathing and heavy drinking of alcoholic beverages, and also sauna bathing during alcohol withdrawal (hangover) phase can undoubtedly create real health risks.
Many of the sauna therapeutic trials used a regular schedule of at least 5 days a week and often daily for one to three months, then several times a week for extended periods.
In some countries the local gymnasium is usually the closest and most convenient and some pool, major sport, or even resort complexes also contain a sauna. Therapeutic Sauna is often carried out in conjunction with physiotherapy or hydrotherapy, gentle exercises within the capability of the person without exacerbating symptoms.
Aggregate (uncorrected) risk of death can estimated to be 10-7 per visit in Finland. In essentially all cases, the victim had diabetes, a heart condition or other serious chronic disease. More than 50% were men over the age of 50, and 30% were over 70; furthermore, most often the victims were intoxicated.

Famous quotes containing the words health, risks and/or benefits:
“The health of the soul is something we can be no more sure of than that of the body; and though a man may seem far from the passions, yet he is in as much danger of falling into them as one in a perfect state of health of having a fit of sickness.”
—François, Duc De La Rochefoucauld (1613–1680)
“The question is whether personal freedom is worth the terrible effort, the never-lifted burden and risks of self-reliance.”
—Rose Wilder Lane (1886–1968)
“One of your biggest jobs as a parent of multiples is no bigger than simply talking to your children individually and requiring that they respond to you individually as well. The benefits of this kind of communication can be enormous, in terms of the relationship you develop with each child, in terms of their language development, and eventually in terms of their sense of individuality, too.”
—Pamela Patrick Novotny (20th century)
