Mental health and physical health are always interrelated and interactive, and mental health will affect people's physical health. For example, if a person is in a state of high tension or depression for a long time, it will be difficult for the immune system to work at its best due to changes in hormone secretion and muscle tension in the body. At this time, people's resistance will decline and diseases will take advantage of it. This is the main reason why people who are in a bad mood are prone to infectious diseases, why people who are in a state of tension for a long time are prone to cancer, and why obese people are prone to heart disease.
People's personality is also closely related to physical health. Generally speaking, people who are withdrawn and narrow-minded will also have some physical diseases due to the influence of emotional state; People who are cheerful and optimistic are often healthier. Therefore, people should not only pay attention to nutrition and physical exercise in daily life, but also cultivate their own sentiments, broaden their minds and avoid persistent emotional tension.
