　　Some people share a laugh to lift their spirits. Others just laugh to enjoy life. Recent research shows that laughter is more than just something to do when someone tells a joke; it is actually good for our health!

　　Besides helping people stay happy, laughter is known to help the human body. Usually when a person experiences stress, his or her immune system is weakened. Laughter is known to fight the bad effects of stress by making hormones that let the immune system recover. Laughter also works as a form of exercise. It helps carry blood to our muscles. A person's blood pressure is usually lower after a good laugh.

　　For those looking for a fun, easy way to good health, here's some doctor's helpful advice: Take a moment each day to enjoy the medicine of laughter!
