So what happens when we laugh? We use 15 different muscles in our face, and laughing is good for every organ in our body. When we laugh, we breathe quickly and exercise the face, shoulders, and chest. Our blood pressure decreases, and our circulation gets better. Our heartbeat is lower, and our brain makes a natural painkiller called a beta-endorphin.
Every minute we laugh is the same as 45 minutes of relaxation. Many doctors around the world believe that laughter helps us get better when we are sick.
Of course, there are many kinds of laughter. We may laugh in different ways when we are in different situations. But we all have a laugh that is special to us.
