Volunteering is a simple way to help others, but it's also a powerful way to help yourself. Beyond the good feelings you'll get from donating your time, and the potential to develop new, meaningful relationships with people in your community, volunteering has a significant impact on your physical health, including a boost to your heart health. New research from Carnegie Mellon University, scheduled to be published in the journal Psychology and Aging, followed more than 1,000 adults between the ages of 51 and 91. Those who volunteered for at least 200 hours a year were 40 percent less likely to develop high blood pressure than those who did not. *Research shows volunteering can cut your overall mortality risk by 47 percent, may lower your risk of depression and anxiety, and even boost your psychological well-being.* The type of volunteer work appeared to be irrelevant. Rather, it was the amount of time spent doing it that mattered. The benefits are particularly pronounced among older adults, a population that tends to slow down once retirement hits. Social interaction, and the stress relief it can provide, is likely one major reason why volunteering has a beneficial effect on blood pressure, as it's a well-known fact that stress elevates blood pressure. Blood pressure aside, volunteering is not only a boon for your heart health. It's likely that one reason volunteering is so beneficial is simply because it keeps you active and on your feet. Instead of resigning yourself to your couch, choosing to volunteer adds many hours of non-exercise activity to your life - a key to optimal health.
