Many people believe that there is some truth in the saying “Laughter is the best medicine.”   1   Laughter helps relieve pain, strengthen the immune system and reduce stress. Laughter stimulates (激发) hormones which make us feel happy. Laughter also increases the flow of blood throughout the body and has benefits which are similar to the ones you get by doing exercise.
  2   Children exposed to funny films and cartoons before major medical procedures are able to cope better with pain and anxiety.   3   These are professional clowns who are sent to hospitals and wards to entertain and distract sick children.
Laughter therapy has become very popular in recent years and as a result, more and more laughter clubs are starting to open up in cities and towns all over the world. At a laughter session, a trained therapist instructs the group to perform a series of exercises which are designed to produce laughter.   4   And it takes them some time to get rid of their inhibitions (心理抑制). They might even start off with fake laughter, but this doesn't matter because our bodies can't tell the difference, and the results are the same. Moreover, laughter is contagious (传染的).   5
