Let’s Laugh Day

Let’s Laugh Day is an annual American holiday dedicated to laughter. It is celebrated on March 19. On this day you should relax and laugh well. Laughter is known to prolong life. So why don’t we laugh more often?


The history of Let’s Laugh Day is not known. They probably decided to establish it so that there would be a special day on the calendar when people could rejoice and be merry.

Laughter is inherent to man from birth. In animals it is practically not found, with the exception of some primates. This, by the way, is another confirmation of Darwin’s evolutionary theory, which concluded that man is the result of the evolution of humanoid apes. Human laughter is a response to external stimuli. The corresponding signal is sent by the brain. Laughter often comes from observing something funny in the present (videos, jokes, actions, etc.). It depends on emotions, so if we remember an event that brought us joy, we may involuntarily laugh or at least smile.

Interesting facts

  • We have so-called mirror neurons, which can be excited by observing other people’s actions. They make laughter and yawning contagious.
  • The infectiousness of laughter began to be actively used on television. It all started with The Hank McCune Show, which aired in 1950. It was the first time used the technique of backstage laughter, which caused a return laugh from the audience, even if what is happening on the screen was not very funny.
  • Laughter lowers the level of cortisol (stress hormone) in the blood. This is one of the main reasons explaining laughter’s ability to prolong life.
