New studies attest to the benefits of giving—not just for the recipients but for the givers’ health and happiness, and for the strength of entire communities.
Of course, you don’t have to shop to reap the benefits of giving. Research suggests the same benefits come from donating to charities or volunteering your time, like at a soup kitchen or a homeless shelter. Here are some of the ways that giving is good for you and your community.
The Benefits of Giving
Giving makes us feel happy. A 2008 study by Harvard Business School professor Michael Norton and colleagues found that giving money to someone else lifted participants’ happiness more that spending it on themselves (despite participants’ prediction that spending on themselves would make them happier). Happiness expert Sonja Lyubomirsky, a professor of psychology at the University of California, Riverside, saw similar results when she asked people to perform five acts of kindness each week for six weeks.
These good feelings are reflected in our biology. In a 2006 study, Jorge Moll and colleagues at the National Institutes of Health found that when people give to charities, it activates regions of the brain associated with pleasure, social connection, and trust, creating a “warm glow” effect. Scientists also believe that altruistic behavior releases endorphins in the brain, producing the positive feeling known as the “helper’s high.”
2. Giving is good for our health. A wide range of research has linked different forms of generosity to better health, even among the sick and elderly. In his book Why Good Things Happen to Good People, Stephen Post, a professor of preventative medicine at Stony Brook University, reports that giving to others has been shown to increase health benefits in people with chronic illness, including HIV and multiple sclerosis.
A 1999 study led by Doug Oman of the University of California, Berkeley, found that elderly people who volunteered for two or more organizations were 44 percent less likely to die over a five-year period than were non-volunteers, even after controlling for their age, exercise habits, general health, and negative health habits like smoking. Stephanie Brown of the University of Michigan saw similar results in a 2003 study on elderly couples. She and her colleagues found that those individuals who provided practical help to friends, relatives, or neighbors, or gave emotional support to their spouses, had a lower risk of dying over a five-year period than those who didn’t. Interestingly, receiving help wasn’t linked to a reduced death risk.
Researchers suggest that one reason giving may improve physical health and longevity is that it helps decrease stress, which is associated with a variety of health problems. In a 2006 study by Rachel Piferi of Johns Hopkins University and Kathleen Lawler of the University of Tennessee, people who provided social support to others had lower blood pressure than participants who didn’t, suggesting a direct physiological benefit to those who give of themselves.
3. Giving promotes cooperation and social connection. When you give, you’re more likely to get back: Several studies, including work by sociologists Brent Simpson and Robb Willer, have suggested that when you give to others, your generosity is likely to be rewarded by others down the line—sometimes by the person you gave to, sometimes by someone else.
These exchanges promote a sense of trust and cooperation that strengthens our ties to others—and research has shown that having positive social interactions is central to good mental and physical health. As researcher John Cacioppo writes in his book Loneliness: Human Nature and the Need for Social Connection, “The more extensive the reciprocal altruism born of social connection . . . the greater the advance toward health, wealth, and happiness.”
What’s more, when we give to others, we don’t only make them feel closer to us; we also feel closer to them. “Being kind and generous leads you to perceive others more positively and more charitably,” writes Lyubomirsky in her book The How of Happiness, and this “fosters a heightened sense of interdependence and cooperation in your social community.”
