Put positive energy into the world and you’ll get it back, research confirms: Performing acts of kindness for seven days boosted happiness and well-being, found a 2018 study in the Journal of Social Psychology. But doing even one kind thing can make you feel great. “Acts of altruism and prosocial behavior are linked to reward-processing areas of the brain,” says study coauthor Lee Rowland, PhD, a chartered psychologist and research affiliate at the University of Oxford. As you start your day, look for ways to perform a random act of kindness, whether for a coworker, your neighbor or a stranger. Bring coffee to a colleague, wheel your neighbor’s recycling bin back in from the curb, text a friend you haven’t talked to in a while to let her know you miss her, or make a small donation to an animal shelter or environmental cause. It’s a pretty nice day, eh?
