Laughter is a Great Medicine

Laughter is a Great Medicine

If you found a medicine that was free and powerful, that cured many ills and was readily available, would you not use it? Well laughter may just be that medicine. And it’s infectious, as the sound of a loud laugh can be more contagious than a groan, a cough or a sneeze.

Psychologists say laughter is a powerful antidote to stress, pain, and conflict. It can quickly bring your mind and body back into balance lighten your burdens, renew hope, reconnect you to others, and keep you grounded. When shared, it binds people together and increases happiness and intimacy.


Laughter creates physical relaxation.A good, hearty laugh releases physical tension and stress, leaving your muscles relaxed for up to 45 minutes after.

Laughter boosts the immune system.Laughter decreases stress hormones and increases both the immune cells as well as antibodies that fight infections. This improves your resistance to illness and infections.

Laughter releases endorphins,the body’s natural morphine like chemicals. Endorphins, produced by the brain promote an overall sense of well-being and the relief of pain. Professor Norman Cousin's in his book, Anatomy of an Illness, described how he used laughter to treat a severe painful immune system disease that he suffered from.

He found that watching comedies helped him feel better and that ten minutes of laughter gave him two hours of pain-free sleep.

Laughter protects the heart.Laughter improves the function of the circulation and increases blood flow, which can help protect against heart attacks, strokes and other cardiovascular problems.

Researchers at the University of Maryland studied the effects on the bloodvessels of people watching either comedies or drama movies. They found that the blood vessels of the group who watched a comedy film behaved normally - expanding and contracting naturally. But in the people who watched the drama their blood vessels tended to constrict and restrict blood flow.

Blood sugar control: One study of diabeteslooked at the effects of laughter on their blood sugar levels.After eating, the diabetics attended a dull lecture. On the following day, they ate an identical meal and then watched a comedy movie. Researchers found, that the group had lower blood sugar levels after the funny move that after the serious lecture.


Laughter dissolves distressing emotions and shifts perspectives. Laughter makes you feel good and the good feeling can linger with you even after the laughter subsides. It is very difficult to feel anxious, angry, or sad when you’re really laughing. Humor helps you keep a positive, optimistic outlook through difficult times, disappointments, and loss.

More than just a respite from sadness and pain, laughter can give you the courage and strength to find new meaning and hope.  Even when distressed, a laugh or even a smile can go a long way toward making you feel better.

It can help you to see situations in a less threatening light. A humorous perspective creates psychological distance, which can help you avoid feeling overwhelmed


Humor and playful interactions strengthen our relationships. They trigger positive feelings and fostering emotional connection. When we laugh with one another, a positive bond is created. This bond acts as a strong buffer against disagreements, tension and disappointment.

Laughing with others is even more powerful than laughing alon
