Did you know that six-year-olds laugh an average of 300 times a day, while adults laugh only 15 to 100 times. No wonder grown-ups tend to get stressed out. We should all laugh more. It’s fun, free, and healthy. And while the idea that “your heart thinks you went to the gym when you laugh” is meant playfully, science shows that laughter genuinely triggers many of the same physical and mental responses we associate with exercise! According to research summarized by the National Library of Medicine, laughter has measurable effects throughout the body:
01 Laughter relaxes the whole body. A good, hearty laugh relieves physical tension and stress, leaving muscles relaxed for up to 45 minutes afterward.
02 Laughter boosts the immune system. It lowers stress hormones and increases immune cells and infection-fighting antibodies, improving resistance to disease.
03 Laughter triggers the release of endorphins. The body’s natural feel-good chemicals, promoting well-being and even temporarily relieving pain.
04 Laughter protects the heart. It improves blood vessel function and increases blood flow, helping protect against heart attacks and other cardiovascular problems.
05 Laughter burns calories. Laughing for 10–15 minutes a day can burn about 40 calories—enough to lose several pounds over a year.
06 Laughter supports mental health. It lifts mood and helps maintain a positive, resilient outlook during stress, disappointment, and loss.
