Saunas may be good for blood pressure
A Finnish study suggests that regular sauna visits can reduce the risk for high blood pressure.
The study, in the American Journal of Hypertension, included 1,621 middle-aged men with normal blood pressure who were followed for an average of 25 years. During that time, 251 developed hypertension.
Compared with those who reported one sauna session a week or less, those who took two to three sessions were 24-per-cent less likely to have hypertension and four to seven visits a week reduced the risk by 46 per cent. The study is observational and does not prove cause and effect, but the senior author, Dr. Jari Laukkanen, a professor of medicine at the University of Eastern Finland, suggested several possible mechanisms. The warmth of the sauna, he said, improves the flexibility of the blood vessels which eases blood flow.
