Laughter is infectious. When laughter is shared, it binds people together. Laughter also triggers healthy physical changes in the body. Laughter strengthens your immune system. It boosts your energy, diminishes pain, and protects you from the damaging effects of stress.
Laughter relaxes the whole body.
A good, hearty laugh relieves physical tension and stress. The levels of two stress hormones, cortisol and epinephrine will actually drop after a dose of laughter. It leaves your muscles relaxed for up to 45 minutes after.
Laughter boosts the immune system.
Laughter decreases stress hormones. It increases immune cells and infection-fighting antibodies, thus improving your resistance to disease.
Laughter triggers the release of endorphins.
Laughter causes positive changes in brain chemistry by releasing endorphins. The body’s natural feel-good chemicals Endorphins promote an overall sense of well-being. They can even temporarily relieve pain.
Laughter protects the heart.
Laughter brings more Oxygen into the body with the deeper inhalations. Laughter improves the function of blood vessels and increases blood flow. Increased Oxygen flow and blood flow can help protect you against a heart attack and other cardiovascular problems.
Laughter encourages right attitudes.
Laughter encourages concentration on right attitudes rather than wrong attitudes. Even in the most difficult of times, a laugh–or even simply a smile–can go a long way toward making you feel better. And laughter really is contagious. Just hearing laughter primes your brain and readies you to smile and join in the fun.
