Chapter 195 Laughing 15 minutes a day is good for the heart

At an academic conference held by the Orlando College of Cardiology in the United States, some scholars said that they have confirmed from different studies that laughing every day is good for the heart.Michael Miller, an expert at the University of Maryland School of Medicine, said: "Exercising 3 times a week, plus laughing happily for 15 minutes a day, is an important guarantee for good health." He said that when a person laughs, the muscles relax and the blood vessels dilate , promotes increased blood flow, which is great for the heart if combined with consistent exercise.

Miller's research team has asked 20 healthy volunteers to watch two movies, one is a light comedy, and the other is a movie that causes a lot of stress, while observing the condition of the blood vessels of the testers.He found that 20 of 14 viewers saw a 35% decrease in blood flow while watching a stressful film, while 19 of them increased blood flow by at least 22% when watching a happy film.Smiling every day is almost as effective for your health as exercising, Miller said.Laughter also relieves stress on your nerves, which is also good for your heart health.
