I already knew about the mental health benefits of volunteering. Studies have shown that volunteering helps people who donate their time feel more socially connected, thus warding off loneliness and depression. But I was surprised to learn that volunteering has positive implications that go beyond mental health. A growing body of evidence suggests that people who give their time to others might also be rewarded with better physical health—including lower blood pressure and a longer lifespan.
Evidence of volunteerism’s physical effects can be found in a recent study from Carnegie Mellon University, published this month in Psychology and Aging. Adults over age 50 who volunteered on a regular basis were less likely to develop high blood pressure than non-volunteers. High blood pressure is an important indicator of health because it contributes to heart disease, stroke, and premature death.
It’s impossible for this study to prove that volunteering was directly responsible for the lower blood pressure readings. People who volunteer may be more likely to do other things, like eat a healthy diet or exercise, that lower blood pressure. But the results are in line with other findings on the topic.
How might volunteering contribute to lower blood pressure? Performing volunteer work could increase physical activity among people who aren’t otherwise very active, says lead study author Rodlescia Sneed, a doctoral candidate in social and health psychology at Carnegie Mellon University. It may also reduce stress. “Many people find volunteer work to be helpful with respect to stress reduction, and we know that stress is very strongly linked to health outcomes,” she says. Read More
