Whether you giggle, chuckle, or guffaw, laughter feels good. Yet, its effect on the body is more significant than the euphoria we experience. Adding extra laughter to your days leads to a healthier heart and a longer life. It can reduce stress, strengthen your immune system, and prevent cardiovascular disease. Even though there are psychological benefits to faking it, not all laughter is powerful on a physiological level.


Types of Laughter

There are two main types of laughter based on brain activity and facial expression. The Duchenne laugh is characterized by identifying the presence of the Duchenne smile.
