First, promote blood circulation and increase metabolic capacity.
According to effective university experiments in the United States, when people watch comedies, most people's pulse will lead to an increase in arterial blood flow velocity, because laughter in the human body occasionally leads to an increase in the contraction of the heart, which leads to an increase in the heart rhythm and a great increase in the output of the heart. Therefore, laughing more can effectively promote the body's blood circulation and increase the body's metabolic capacity.
Second, analgesic and antihypertensive effects.
When we laugh, nerve cells in the brain release a substance called B- endorphin, which is an analgesic without side effects. Unlike morphine, it is a hormone in the brain, which is responsible for transmitting information that produces pleasure and relieves pain. At the same time, B- endorphin will relax some blood vessel walls, such as cortical tissue, thus repairing blood vessels and lowering blood pressure.
Third, promote digestion.
Laughter is also an effective digestive agent. When you laugh happily, your shoulders will stir, your chest will swing and your diaphragm will vibrate, so that your internal organs will be massaged and you will feel good. Venting can increase the secretion of digestive juice, and joyful laughter can promote the activity of digestive tract, thus increasing appetite, helping digestion and absorption of food and enhancing gastrointestinal function.
Fourth, promote lung function.
When we laugh, it is easy to cause an increase in lung activity, which can effectively eliminate a lot of carbon dioxide. Laughter can promote smooth breathing and effectively promote lung function.
When you laugh, your body will have 80 groups of muscle twitches. Laughing 1 min is equivalent to doing 45 minutes of exercise.
Five, lose weight
The researchers pointed out that when you laugh, your body will have 80 groups of muscle twitches, and laughing 1 minute is equivalent to doing 45 minutes of exercise. That is to say, the human body consumes 20% more calories when laughing than when it is serious, so if you laugh happily for 10- 15 minutes every day, it is equivalent to consuming 50 kilocalories, losing 2 kilograms a year, and more importantly, promoting the abdominal muscles that seldom exercise.
Sixth, relieve stress
Laughter is the best way to relax. Whether you really laugh or fake it, it's good for your body and mind. When you really laugh, the pleasure center of the brain will be excited; In the face of stress and negative emotions, trying to fake a smile will also stimulate the relevant areas of the brain related to happy feelings.
