問題詳情

A recent study conducted at a university in the United States showed that laughing helps blood vessels work moreefficiently in the same way that exercise does. Doctors don’t suggest that people stop exercising, but instead encourageeveryone to try laughing for fifteen minutes a day. The scientists still don’t know why laughing is so healthy, however. Isit because beneficial chemicals are released from your brain when you laugh? Or is it because laughing exercises yourabdominal muscles and lungs and increases the amount of oxygen in your blood?Another benefit of laughing is that it boosts the immune system by increasing the body’s ability to fight off colds andthe flu, so people who laugh more often get sick less often. Laughing can also lower blood pressure and can reduce stresshormones. Laughter causes the release of the body’s natural painkillers, so people with headaches and other pain feelbetter after laughing. In another study, nurses told jokes to some patients after medical treatment. The patients who weretold jokes reported less pain than those who were not told jokes.Most hospitals have laughter departments these days. For sick children, some hospitals have clown doctors. These arenot real doctors, but are actors dressed as clowns with white faces, bright red noses, col orful costumes, and very big shoes.They have funny names and sometimes sing songs or do magic tricks. It’s frightening for children to be sick in hospitalbecause they are away from their home and family, and often they don’t understand their illness. Clown doctors help themto laugh and feel happier while they receive their treatment. Adult patients love them, too!
