Laughter can help relieve tension in even the heaviest of matters.
Laughing is also good for your respiratory system.
Humor does not diminish the pain - it makes the space around it get bigger.
The lesson adults can learn here is that the world is filled with things for our enjoyment.
It is still not clear from this study how laughter can directly help the heart but other studies have shown that laughter is beneficial for every system in the body.
Now, a recent study from cardiologists at the University of Maryland, has shown that laughter may have a beneficial effect on the heart.
