National Tell a Joke Day

Aug 16 2015

Why shouldn't figure skaters tell jokes on the ice?  The ice might crack up!


Today, let's celebrate laughter.  (It's good for you!)

  • Laughing releases endorphins (the same brain chemicals that give you a runner's high).
  • Vanderbilt University research found that laughing for 10-15 minutes burns 50 calories!
  • Laughing lowers your body's coritsol epinephrine levels and encourages it to use macrophages--boosting your immune system against infections and viruses.
  • William Fry, who researches laughter, found that it took 10 minutes of exercise on a rowing machine for his heart rate to reach the same point as it was after one minute of laughter.  He said, "the effects of laughter and exercise are very similar."

So keep training strong--but don't forget to laugh a little, too!
