A team led by researchers from the University of Eastern Finland, Kuopio, has examined the impact of saunas on fatal heart events, along with all-cause mortality.
They surveyed 2,315 men aged 42 to 60 years old from eastern Finland -- first in the mid-to-late 1980s then for a follow up about 21 years later.
Compared to men who had one sauna session a week, those visiting two to three times had a 22 percent lower chance of dying from sudden cardiac death, and those with four to seven sauna sessions a week had a 63 percent lower chance.
Similar trends were seen with fatal coronary heart disease and with fatal cardiovascular disease.
Among all causes, men with four to seven sessions a week had a 40 percent lower chance of dying than those who went only once.
