Laughter makes you feel good. And the good feeling that you get when you laugh remains with you even after the laughter subsides. Humor helps you keep a positive, optimistic outlook through difficult situations, disappointments, and loss. More than just a respite from sadness and pain, laughter gives you the courage and strength to find new sources of meaning and hope. 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.

Humor plays an important role in relationships from initial attraction to long-term commitment. In new relationships, humor can be an effective tool not just for attracting the other person but also for overcoming any awkwardness or embarrassment that arises during dating and the process of getting to know one another. In longer-term relationships, humor can keep things exciting, fresh, and vibrant. It can also help you overcome conflicts, disagreements, and the tiny aggravations than can build up over time and wreck even the strongest of relationships. When laughter is shared, it binds people together and increases happiness and intimacy. Laughter also triggers healthy physical changes in the body. Humor and laughter strengthen your immune system, boost your energy, diminish pain, and protect you from the damaging effects of stress. Best of all, this priceless medicine is fun, free, and easy to use.

Laughter protects the heart.  A recent study showed that people with heart disease were 40% less likely to laugh in a variety of situations compared to people of the same age without heart disease. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems. Researchers from the University of Maryland conducted tests about the endothelial function of arteries in a group volunteers with an average age of 33 years. The results showed that when the volunteers watched films that made them laugh, the functionality of the endothelium was significantly better. This translates into better blood flow in the arteries. Laughter relaxes the body. Laughing relieves tension and relaxes our muscles, an effect that has been shown to last for up to 45 minutes after. Laughter puts you in a better mood. Laughing triggers the release of hormones in the brain called endorphins. Endorphins promote an overall sense of well-being. Laughter decreases pain. Endorphins also temporarily relieve pain and are often called the body's natural pain killer. Laughter decreases anxiety and stress. There is a decrease in stress hormones such as cortisol and adrenaline as a result of laughing. And people who laugh more tend to report lower anxiety and feelings of stress. Laughter may boost the immune system. Some studies show that laughing increases immune cells and infection-fighting antibodies, thus potentially improving our resistance to disease.
