Feeling run down? Try laughing more. Some
researchers think that laughter is the best
medicine it helps you feel better and puts
energy back into your bodies.
I believe that if people can get more laughter in
their lives, they are a lot better off, says
psychologist Steve Wilson. They might be
healthier, too.
Theres nothing better than a good laugh to
forget stress and pain. Studies at the University
of Chicago show that a great sense of humor
can add up to eight years to your life!
So what actually happens when we laugh? When
we laugh our bodies change. We use muscles* in
our face and in our whole body. Our pulse rate*
and blood pressure go up and we breathe faster.
This sends more oxygen* to all parts of our
bodies. In this way, laughter is like exercise. It
makes us feel good and it even burns calories!
M. Buchowski, a researcher from Vanderbilt
University, measured the calories people use
while laughing. He found out that 10-15
minutes of laughter burned 50 calories. But
dont think you can use laughter to lose weight.
It would take over 24 hours of laughter to lose
one kilo!
How do these physical changes affect us?
Research has shown that:
Laughter relaxes the whole body. It reduces
stress, leaving your muscles relaxed for up to
45 minutes.
Laughter helps the body to fight diseases.
Laughter helps us forget pain. When we
laugh, the brain makes chemicals that help
us feel good so we feel pain less.
Laughter is good for the heart. It can help
prevent heart attacks and other heart
problems.
Can a laugh a day keep the doctor away? The old
saying that laughter is the best medicine seems
to be true. The recipe for a healthy life includes
exercise, healthy food and a good laugh several
times a day.
