Sadness and sorrow is a kind of worry, melancholy, sorrowful emotional response to some unsatisfactory and unpleasant things. In real life, when people are in a situation where things are not what they want, when normal activities are hindered, when hopes for success are thwarted, when desires of the heart are not fulfilled, troublesome sorrow and sadness will follow. Generally speaking, sadness and sorrow, as a kind of emotional activity, are a normal response of the human body to external things and do not pose any harm to the body. On the contrary, temporary and mild sadness can help to regain awareness of the setbacks suffered and help people to gain a correct understanding in their minds, which is beneficial to physical and mental health. It would be abnormal if a person had no sorrow at all when his parents died suddenly, or if he had no feeling of worrying about his country when it fell and was invaded by foreigners. However, when a person’s sorrow is too much, or last too long, more than the limits of the body’s own regulation and bear the load, and in the ideological understanding, and can not actively or passively transfer this bad mood, it becomes a pathogenic factor, the organism poses a danger, serious people can be killed because of excessive worry. China’s classical masterpiece “Dream of the Red Chamber” in the Lin Daiyu, aloof, sentimental, the slightest discomfort, will be secretly crying and tears, and finally died of sorrow. The story of Lu You, a famous poet of the Song Dynasty, and his cousin Tang Wan also illustrates the fact that excessive melancholy can kill. Chinese medicine believes that the main function of the lung is to master qi. Here, there are two concepts of qi, one is that the lungs are the main respiratory qi, that is, the inhale the natural air. Exhale the waste gas in the human body. The second is that the lung is the main body of Qi. That is, the lungs will be inhaled fresh air supply to all organs of the body. Thus keeping the whole body functional activities abundant and strong. When the lungs are injured by sad emotions, there will be changes in both the breath of Qi and the Qi of the whole body. For example, when a person cries incessantly because of sadness, that person’s breathing tends to accelerate. We often say that a small child cries up and down. This is because the lungs are injured by grief, and the lungs need more air to be replenished, so the breathing is accelerated, that is, the process of qi intake is accelerated. We also commonly see that sometimes a person who cries too much for too long is as soft as a noodle, and the person next to him can’t even pull him up, which is a deficiency of the whole body’s qi due to lung qi damage. In terms of symptoms, the main symptoms of sad lung are shortness of breath, cough, phlegm or no phlegm, general weakness, and cold skin. It is easy to catch a cold, which is called Lung Qi deficiency in Chinese medicine. Thus, it seems that sadness hurts the lungs, and by the same token, happiness hurts the heart, anger hurts the liver, fear hurts the kidneys, and thinking hurts the spleen are all justified. Usually, in addition to exercising, you should learn to regulate your mood so that you can have a healthy body.
