What are the factors that affect health?

(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 fruits, on the other hand, they should also accept the harm it brings. Nature nurtures human beings, but at the same time it produces, exists and spreads all kinds of harmful substances that endanger human health at any time. The sudden 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 has brought 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 human beings want to be healthy, they must persistently improve, beautify, purify and optimize the environment.

(2) Biological factors Among biological factors, genetic factors and psychological factors are the most important factors affecting human health. 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 and prevention of diseases, and negative psychological factors can cause many diseases. A positive mental state is a necessary condition for maintaining and improving 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. Positive and optimistic mood can stand the test of victory and failure. In short, mental state is a reflection of social environment and living environment.

(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 development, human beings have long recognized that lifestyle is related to health, but various infectious diseases that endanger human life have always been the main cause of human death. The influence of lifestyle factors on health is ignored. It was not until the 1960s of 19 that people gradually discovered that lifestyle factors after birth accounted for an increasing proportion of all deaths. For example, 50% of the annual 1976 deaths in the United States are related to unhealthy lifestyles. This shows how important it is to develop good living habits for health.

(4) The factors of medical care service are very complicated, and medical care service is an extremely important factor. The World Health Organization classifies health care services into primary, secondary and tertiary levels, and achieving primary health care is the common goal of all countries in the contemporary world.
