CHICAGO (AP) — Frequent sauna baths may help you live longer, a study of Finnish men suggests. It would be welcome news if proven true — in Finland where hot, dry saunas are commonplace, and for Americans shivering in a snowy Nordic-like winter. Previous research suggested that saunas might improve blood vessel function and exercise capacity, and lower blood pressure in patients with hypertension. The new study links long, hot sauna baths with even more benefits, including fewer deaths from heart attacks, strokes, various heart-related conditions and other causes.
