HARVARD HEALTH: Sauna use linked to longer life, fewer fatal heart problems
After shoveling for days, breaking up ice dams, and now shivering in this week’s frigid temperatures, I wouldn’t mind sitting in a sauna for a bit. A new report in JAMA Internal Medicine makes this pastime even more appealing: regularly spending time in a sauna may help keep the heart healthy and extend life.
Researchers from the University of Eastern Finland tracked 2,300 middle-aged men for an average of 20 years. They categorized the men into three groups according to how often they used a sauna each week. The men spent an average of 14 minutes per visit baking in 175° F heat. Over the course of the study, 49% of men who went to a sauna once a week died, compared with 38% of those who went two to three times a week and just 31% of those who went four to seven times a week. Frequent visits to a sauna were also associated with lower death rates from cardiovascular disease and stroke.
The results don’t surprise Dr. Thomas H. Lee, a cardiologist at Harvard-affiliated Brigham and Women’s Hospital and founding editor of the Harvard Heart Letter. “The cardiovascular effects of sauna have been well documented in the past. It lowers blood pressure, and there is every reason to believe that its effects are good for blood vessels,” says Dr. Lee.
