(1) Environmental factors The environment has great influence on human health. Whether it is the natural environment or the social environment, on the one hand, human beings should enjoy its achievements, on the other hand, they should also accept the harm it brings. Nature has nurtured human beings, but at the same time it also produces, exists and spreads all kinds of harmful substances that endanger human health at any time. The abrupt change of climate, airflow and air pressure will not only affect human health, but even bring disaster to human beings. In the social environment, the change of political system, the development of social economy and the progress of culture and education are closely related to human health. For example, economic development brings waste water, waste gas, noise and waste residue, which is extremely harmful to human health. Bad customs and harmful ideology also hinder human health. Therefore, if people want to be healthy, they must make unremitting efforts to improve, beautify, purify and optimize the environment.
(2) Biological factors Among the biological factors, the most important factors affecting human health are genetic factors and psychological factors. Modern medicine has found that there are not only two or three thousand kinds of genetic diseases, but also the incidence rate is as high as 20%. Therefore, it is of special significance to attach importance to the influence of heredity on health. Psychological factors are closely related to the occurrence, prevention and treatment of diseases. Negative psychological factors can cause many diseases, and positive psychological state is a necessary condition to maintain and improve health. Medical clinical practice and scientific research have proved that negative emotions such as anxiety, resentment, sadness, fear and anger will make various systems of the human body dysfunctional, which will lead to insomnia, tachycardia, elevated blood pressure, loss of appetite, menstrual disorders and other diseases. A positive and optimistic attitude can stand the test of victory and failure. In a word, mental state is a reflection of social environment and living environment, and it is an important factor affecting health.
(3) Lifestyle factors Lifestyle refers to a series of living habits, living systems and life consciousness formed by people under the long-term influence of certain culture, nationality, economy, society, customs and family. In the long process of human development, although it has long been recognized that lifestyle is related to health, various infectious diseases that endanger human life have always been the main cause of human death, and the influence of lifestyle factors on health has always been ignored. It was not until the 1960s (19) that people gradually discovered that among all the causes of death, the factor of acquired mode became more and more important. For example, from 65438 to 0976, 50% of the annual deaths in the United States were related to unhealthy lifestyles. It can be seen how important it is to develop good living habits for health.
