The research is in: Doing nice for others does a body good. Maybe you were thinking that one of the best things about volunteering is getting a free pass to leave the office a few days a year, or just the pleasant feeling of accomplishment you get for helping others. As nice as those are, a recent study from Carnegie Mellon also found a direct link between volunteer work and decreased risk of high blood pressure, a major risk factor for heart attack and stroke. The study published in the journal of Psychology and Aging, included almost 1,200 people between the ages of 51 and 91 , but the health benefits of volunteering among younger people have also been reported. Earlier this year , a study with the High School kids indicated volunteerism could lead to lower inflammation, cholesterol and body mass index.
