Laughter can offer both physical and mental health benefits.

“There’s actually some connections to stress relief, but also a long-term impact of actually improving your immune system,” said Dr. Kia-Rai Prewitt, a psychologist with the Cleveland Clinic. “So when you have reduced stress, that could have long-term positive effects and whether or not you get sick.”

Other health benefits of laughing include increasing oxygen to your body and increasing blood flow, which can help your heart.
