History of National Let's Laugh Day

Every year, on National Let’s Laugh Day, we are reminded to keep things light and pep things up with a little humor. If you have been in the doldrums for a while now, or haven’t been feeling too good, then you need to laugh the worries away and take it easy. Laughter is, after all, the best medicine, and it is just what the doctor prescribed for March 19!

Jokes have long been the best way to provide comic relief. The world’s oldest joke can be traced back to 1900 B.C. Laughter can also be contagious. This is why laugh tracks were added to television shows to cue when the audience is supposed to laugh and to indicate when a comedic scene happens. The first American television show to use a laugh track was in 1950, in “The Hank McCune Show.”  

Where frowns cause wrinkles, laughing creates adorable crinkles that are good for the muscles. ‘Laughter yoga’ is now quite a popular activity, in which muscles of the face, abdomen, and lungs are engaged using laughter as the core exercise. Laughter also releases endorphins and lowers the stress hormone, cortisol, in the body.
