Did you know that a smile improves your immune system?
Scientists have found that when we smile, our body releases more white blood cells than usual. And the main purpose of white blood cells is to protect the body from infectious diseases, as well as from foreign invaders.
So, a smile actually makes our body more immune to disease and thus helps our good health. In fact, this is the main reason why celebrities visit children’s hospitals. If they can make children smile, it will help their overall health to some extent.
With that in mind, don’t smile on your own, but make others smile!
