The brain is wired for laughter. The more you laugh, the better you feel, so what's stopping you? When you laugh, you not only lose weight and exercise your body, but you also generate more antibodies that help you fight disease. Laugh yourself to health and happiness, it's easy.

Clearly, humor is infectious. The sound of roaring laughter is more contagious than any cough, sniffle, or sneez and when laughter is shared, it binds people together and increases happiness.

The domino effect of joy and amusement triggers healthy physical changes in the body. Laughter strengthens your immune system, boosts your energy, diminish pain, and protect you from the damaging effects of stress. Why do we so often ignore this priceless medicine that is fun, free, and easy to use?

A good, hearty laugh relieves 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 immune cells and infection-fighting antibodies, thus improving your resistance to disease. Laughter triggers the release of endorphins, the body’s natural feel-good chemicals. Endorphins promote an overall sense of well-being and can even temporarily relieve pain. Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems.

If you are a healthy skeptic, you will not believe me, but the hard evidence from American College of Cardiology member Michael Miller, M.D., of the University of Maryland, has proved that laughter helps your blood vessels function better because it acts on the inner lining of blood vessels, called the endothelium, causing vessels to relax and expand, increasing blood flow and improving the overall function of your heart and brain.

Since we are all up for some improvement, the following videos will help you get some of the laughter you need to feel better.
