The benefits of laughing often

1, promoting digestion. Laughter is also an effective digestive agent. When you laugh happily, your shoulders will stir, your chest will swing, your diaphragm will vibrate, and your internal organs will be massaged. Good emotional catharsis can increase the secretion of digestive juice. Happy laughter can promote the activity of digestive tract, thus stimulating appetite, helping you digest and absorb food, and enhancing gastrointestinal function.

2, promote lung function, because when we laugh, the nose and mouth open, the lungs expand, the vital capacity increases, and a lot of oxygen is inhaled to bring out carbon dioxide, so laughter can not only make the respiratory system smoother, but also promote lung function.

3, relieve stress, laughter is the best way to relax, whether it is real or fake smile, it is good for both 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.

4, analgesic and antihypertensive effects, when we laugh, nerve cells in the brain will release a substance called B- endorphin, which is an analgesic without side effects. Unlike morphine, morphine is the hormone responsible for transmitting pleasure and analgesic information in the brain; At the same time, B- endorphin will relax some blood vessel walls, such as cortical tissue, thus repairing blood vessels and lowering blood pressure.
