What is the health benefit of laughing 15 minutes every day?

Laughing 15 minutes every day is good for the heart, which was put forward by some scholars at the academic conference held by the College of Cardiology in Orlando, USA. Michael Miller, an expert at the University of Maryland School of Medicine, said: "Exercising three times a week, plus laughing happily 15 minutes every day, is an important guarantee for good health." He said that when people laugh, muscles relax and blood vessels relax, which promotes the increase of blood flow. If combined with continuous exercise, it is of great benefit to the heart.

Miller's research team invited 20 healthy volunteers to watch two movies, one is a light comedy, and the other is a movie that caused great stress, while observing the blood vessels of the testers. He found that when watching nervous movies, the blood flow of 14 of the 20 audience decreased by 35%; When watching happy movies, the blood flow of 19 increased by at least 22%. Miller said that smiling every day is almost as healthy as taking part in exercise. Laughter can also relieve nerve stress and is good for heart health.

Tips

Don't be angry for more than 3 minutes. Because when people are angry or angry, their breathing is accelerated, their alveoli are dilated, their oxygen consumption is increased, their liver glycogen is lost in large quantities, their blood flow is accelerated, their blood pressure is increased, and their hearts are beating violently, so the whole body will be in a state where normal physiological functions are out of control. So people should be less angry and vent their anger as soon as possible.
