Men's Hert Health Helped by Donating Blood
Middle-aged men who donate blood tend to have significantly fewer heart attacks than non-donors, medical researchers say.
Writing in the American Journal of Epidemiology, scientists at Finland's University of Kuopio found in their study of more than 2,800 middle aged men that blood donors had an 88 percent reduced risk of heart attack when compared with those who reported not giving blood.
Study results raised speculation that individuals who donate their blood tend to reduce iron levels -- considered a risk factor for heart attack -- in their blood.
Researchers also say those who donated blood tended to be in better physical shape, and were more youthful in appearance than non-donors.
