We all know that laughter makes us feel good and we enjoy it. Most of us didn’t know why until now. When we laugh, our breathing quickens, which exercises the diaphragm, neck, stomach, face and shoulders. Laughter increases the amount of oxygen in the blood, which not only helps healing and improves circulation, it also expands the blood vessels close to the skin's surface. This is why people get red in the face when they laugh. It can also lower the heart rate, dilate the arteries, stimulate the appetite and burn up calories. Professor William Fry at Stanford University found that 100 laughs are equal to a ten-minute aerobic workout on a rowing machine. Medically speaking, this is why a good laugh is good for you. As we age we become more serious about life. A preschooler laughs on average 400 times a day, but by the time we are an adult we are only laughing an average of 15 times a day!
Richard Davidson, professor of psychology and psychiatry at the University of Wisconsin in Madison performed many studies on laughter. He hooked people up to EEG (electroencephalograph) machines, which measure brain wave activity, and then showed them funny movies. When people laughed or smiled, it made the left hemisphere of the brain surge with electrical activity. He found that intentionally producing smiles and laughter moves brain activity toward spontaneous happiness.
Arnie Cann, professor of psychology at the University of North Carolina, revealed that humor has a positive result in preventing stress. Cann did a study on depressive patients where he divided them into two groups and showed each group videos for 3 weeks. The group that watched comedy videos had a greater improvement than the group that watched videos that had no humor involved. He also found that people with ulcers frown more than people without ulcers.
When we laugh we stimulate the body’s natural painkillers and endorphins or “feel good” boosters, which aid in reducing stress and healing the body.

When Norman Cousins was diagnosed with the debilitating illness ankylospondylitis, (calcification of the vertebrae of the spine) the doctors told him they could no longer help him and that he would live in excruciating pain before he died. Cousins checked into a hotel room and hired every funny movie he could find: The Marx Brothers, Airplane and The Three Stooges, etc. He watched and re-watched them over and over, laughing as hard and loud as he could.
