It's generally understood that helping out others makes a person feel nice, but that experience goes beyond just the feel-good glow of altruism. Studies have found that helping others has tangible benefits, both mental and physical, from lowering your blood pressure to reducing feelings of depression. And research hasn't found any significant difference in the types of volunteering—any kind of helpful act can create benefits. "Research has shown that there's evidence volunteer work promotes that psychological well-being you're talking about," said Rodlescia Sneed, a public health research associate at Michigan State University who has studied the impacts of volunteering. "In my own work I've shown it's linked to improvements in factors like depressive symptoms, purpose in life, and feelings of optimism."
