Psychological balance is an important foundation of health.

Traditional Chinese medicine believes that emotional abnormality (excessive mental stress) is a disease, not a disease. Because of mental and emotional stress, blockage of meridians and the loss of qi and blood, the harm to the body is much more serious than "external evil".

When people are in a state of tension, the secretion of adrenocortical hormone increases, and the deposition rate of lipid substances on the inner wall of arteries will be several times or even dozens of times higher than that in a calm mood.

Qi and blood stagnation caused by shortness of breath can block a healthy person's cardiovascular artery spasm to 100% in a few minutes, killing people.

People really get angry. Studies show that anger can really lead to sudden cardiac death due to the sudden stop of blood supply to the heart. In the Romance of the Three Kingdoms, Zhuge Liang's "three Zhou Qiyu" and "cursing Wang Lang to death" both killed Zhou Yu and Wang Lang by arousing their anger.

The importance of mental health. The World Health Organization regards psychological balance as one of the four cornerstones of health, which shows its importance.

If a person is positive and optimistic, qi and blood will flow freely throughout the body, meridians will not be blocked, vitality will not be excessively exhausted, and people will not get sick. On the contrary, if a person is negative, sad, afraid and angry, he will lose more yang, his blood will stay somewhere in his body, and his body will become weak unconsciously. If he is wet and turbid, he will form a cyst, which will not be relieved for a long time and eventually form a tumor.

Since ancient times, people have said that kindness and generosity are good medicines for health.

Darwin also said, "goodness will lead to longevity."

Modern medicine has found that the biggest mental hidden danger of people is that they are too narrow and selfish to lose their spirit.

The University of Pittsburgh School of Medicine has spent eight years following up, which shows that unkind people have short lives and only have themselves in their hearts.

As the saying goes, "Don't do it with small evils", always think of others, do things that harm the interests of others or even others, and be depressed for a long time. The loss of vitality will easily lead to yin-yang imbalance, increase the probability of suffering from diseases such as hypertension, cardiovascular and cerebrovascular diseases and cancer, and directly affect the quality of life and longevity. History has proved that people can't be proud for a while, and everyone must learn to be a man first. For example, people who like to calculate others and make enemies everywhere will eventually suffer.

Therefore, a man should have a kind heart. Meeting is fate. It is really good to advocate win-win and win-win now. You don't know those people who live long at all times and in all countries. Their similarities are broad-minded, optimistic and cheerful, kind-hearted, easy-going, hardworking and contented, kind-hearted, indifferent to fame and fortune, and uncontested.

The philosopher said, "Character determines fate."

Psychologists say: "Personality determines health." Because personality determines mentality and mentality determines health, personality is closely related to health and disease.

Just as blood types are divided into type A, type B and type O, human personality is also divided into type A, type B, type C and type D4. People with type A personality are competitive, time-oriented and self-motivated, and strive to occupy the position of leader. This kind of people have great psychological pressure and are easy to get nervous and excited, and the risk of suffering from hypertension and cardiovascular and cerebrovascular diseases is 2-3 times that of ordinary people; People with type C personality always submit to humiliation and suppress their emotions in interpersonal communication, and such people are prone to cancer; Type D personality, also known as "sad personality", shows negative sadness and loneliness, and is a risk factor for cardiovascular and cerebrovascular diseases. People with type B personality are very satisfied with the status quo, happy with contentment, moderately relaxed in life, and have no major emotional fluctuations. Such people have the highest probability of entering the ranks of "longevity".

Unnecessary is more harmful to health. As the saying goes, "Illness comes from eating, annoyance from thinking, and anger from comparison." Research shows that correct comparison can be a driving force for people to work hard, but blind comparison will make them more angry and harmful to health.

Those who feel aggrieved and lost because their friends have made progress faster than themselves or become richer than themselves are at higher risk of heart disease, ulcer, high blood pressure and other diseases.

In real life, people who are jealous and angry are really hard to be healthy, and it is even harder to live long.

Professor Elma, an American physiologist, found that getting angry 10 minutes consumes the same amount of energy as running in a 3000-meter race. When a person feels angry, his muscles, hair, blood sugar, heart rate, respiratory rate, intestinal tract and even the temperature of his fingers will react. The secretion of stress hormones such as adrenaline and angiotensin is toxic, especially when blood pressure rises instantly, it is easy to cause cerebral hemorrhage and myocardial infarction, which seriously harms people's health. Alma warned that "anger equals suicide"

. The ancients said that "nourishing the heart is quiet." "Quiet" means not getting angry, losing your temper and asking for trouble. People should have a good mentality of not being jealous of others, not laughing at others, not doing anything and competing with others, and a mentality of "not being too happy, but not too worried".

In life, we should learn to stress principles on major issues, ignore minor issues, be more tolerant and less resentful. People are naturally physically and mentally healthy.

Begging will only bring endless troubles. However, his cheerful and optimistic personality, carefree cultivation, satisfaction with life, the concept of letting nature take its course and happiness will accompany him all his life.
