A hot new therapy?
From Chicago, Ill., at a meeting of the American Heart Association
Spending time in a sauna improves heart function in people with chronic heart failure, report researchers from Japan. For 2 weeks, 20 people spent 15 minutes a day, 5 days a week, in a 60C sauna and then 30 minutes lying on a bed wrapped in blankets to maintain an increased body temperature. The other 10 volunteers lay on a bed without blankets at room temperature for 45 minutes a day, 5 days a week.
