               Regularly spending time in a sauna(桑拿房) may help keep the heart healthy and extend (延长) life,say Finnish scientists in the journal JAMA Internal Medicine.

               Researchers from the University of Eastern Finland (UEF) studied 2,300 middle-aged men for an average of 20 years. They divided the men into three groups according to how often they used a sauna each week. Over the course of the study,49% of men who went to a sauna once a week died,compared with 38% of those who went two to three times a week and just 31% of those who went four to seven times a week. Frequent visits to a sauna were also linked with lower death rates from heart disease.

               The results dont surprise Dr. Thomas H.Lee,founding editor of the Harvard Heart Letter. aThe beneficial effects of a sauna have been well documented in the past. It lowers blood pressure,and there is every reason to believe that its effects are good for your heart,” says Dr. Lee.

               Sauna use is deeply rooted in Finnish culture. A nation of 5. 5 million people,Finland has as many saunas as television sets — around 3. 3 million. Most of the saunas are in peoples homes,although they’ re also in offices and factories.

               The very nature of the Finnish sauna is designed to reduce stress,the researchers say. The sauna has been a gathering place for family and friends for centuries. And a basic sauna rule; which discourages people from discussing controversial topics while bathing,is taught to the Finns during childhood.

               The Finnish researchers suggest that saunas may provide similar benefits to exercise because the high temperatures can drive heart rates to levels often achieved by moderate-intensity(中等强度的) physical activities.

               So can sitting in a sauna take the place of exercising? I don't  know that I would take a sauna for exercise ,” Dr. Lee says. “But exercising and then taking a sauna seems like a very healthy lifestyle."
