Traditional sauna
The Traditional sauna uses a heating element to increase the ambient air temperature. Sauna has been widely used in Finland for centuries. Today there are 2 million saunas in Finland, which has a population of 5 million. During a short sauna the average person will lose a pint of sweat. Patients afflicted with asthma or psoriasis have reported symptom relief. A 2015 study found that frequent sauna usage lowered men's risk of fatal cardiovascular disease and premature death from other causes. The study's conclusion reports, "Increased frequency of sauna bathing is associated with a reduced risk of SCD, CHD, CVD, and all-cause mortality. Further studies are warranted to establish the potential mechanism that links sauna bathing and cardiovascular health."
