"Heres a bit of good news for folks who enjoy sitting in a superheated room and sweating profusely Finnish researchers say regular sauna bathing may help men to live longer. The study which was published Monday in JAMA httpjama.jamanetwork.comjournal.aspx is the latest in a series of papers to explore the potential cardiovascular health benefits of chilling out in a room heated to degrees Fahrenheit. Our results suggest that sauna bathing is a recommendable health habit wrote Dr. Jari Laukkanen a cardiologist a the Institute of Public Health and Clinical Nutrition University of Eastern Finland. The only catch is nobody can explain exactly why this is the case. Further studies are warranted to establish the potential mechanism that links sauna bathing and cardiovascular health wrote Laukkanen and his colleagues. The researchers based their conclusion on a database of of  Finnish men who have had their health tracked since . Study participants were all aged  to  with a median age of . Those men who enjoyed a sauna two or three times a week had a  lower risk of experiencing a fatal episode of coronary heart disease or cardiovascular disease compared to those who took just one sauna a week according to researchers. The apparent health benefits for men who used the sauna four to seven times a week was even greater They had a  lower risk of similar incidents when compared to men who used the sauna only once a week researchers said. The higher frequency of sauna bathing was related to considerable decreased risks of sudden cardiac death fatal coronary heart disease fatal cardiovascular disease and allcause mortality the authors wrote. The researchers said a similar health benefit was unlikely to be found in steam rooms and hot tubs due to the unique conditions of Finnish saunas. A traditional Finnish sauna has dry air  to  humidity and a recommended temperature of  degrees to  degrees. Humidity is increased temporarily by throwing water on the hot rocks of the sauna heater and most Finns are accustomed to using a sauna once a week. On average the men in the study used a sauna twice a week at a temperature of about  degrees. The average time spent in the sauna was about  minutes researchers say. The superheated conditions of a sauna provoke a variety of physical reactions. Heart rate can climb to  or  beats per minute  similar to low or moderateintensity exercise  and sweat is secreted at a rate of about  pounds per hour. High temperatures also causes the body to flow more blood to the skin and less to internal organs. Previous studies have suggested that sauna bathing might have some harmful effects whereas our results indicated a protective effect the authors wrote. The researchers noted that only  to  of sudden deaths occurred within  hours of sauna bathing. Alcohol intake was a major contributing factor in those cases authors wrote. In an accompanying editorial Dr. Rita Redberg a cardiologist and professor of medicine at the University of California San Francisco speculated on a number of possible reasons for the observed benefits. Although we do not know why the men who took saunas more frequently had greater longevity whether it is the time spent in the hot room the relaxation time the leisure of a life that allows for more relaxation time or the camaraderie of the sauna clearly time spent in the sauna is time well spent Redberg wrote.
