beats more slowly, your blood pressure goes down. You breathe more deeply, and so more oxygen (氧气) is
carried round your body. Chemical changes happen too. Happy-feeling chemicals go to your head and make
you feel that all is well in the world. The next time you laugh, notice that you are feeling relaxed afterwards.
Doctors have studied the results of laughing with very sick patients. First, if a patient has a lot of pain, it
is a good idea to watch funny films. One person with cancer described his stay in hospital."After I laughed
hard for ten minutes, the pain would go and I would have about two hours of pain-free sleep." Laughing can
help you get better, especially if you have a very bad illness. Again, chemical changes happen in the body.
As a result the body fights the disease and may help the patient get better.
But laughing is good for healthy people, too. Laughing helps people relax. If there is a problem and you
are able to laugh about it, you may feel more relaxed.
In Bombay in India there are 48" laughing clubs". People meet and laugh together! They may laugh
quietly or silently. When they laugh very strongly, this exercises the whole body. This is part of the Indian
study of human health. So, next time, explain to your friends why you are laughing. "It"s keeping me healthy.
