environment
Environment is the most influential factor to human health, which is mainly divided into natural environment and social environment. The natural environment, including changes in temperature, climate, air quality and air pressure, will affect people's health. Social environment mainly includes interpersonal communication, political change, social and economic development, etc. For example, if you live in a place where waste gas and waste water are seriously polluted, it is always easy to breed various diseases, and the social environment is poor, which leads to people's depression and is harmful to their health.
genetic gene
Heredity is of great significance to human health. Both parents' health and genetic diseases may be passed on to the next generation through genes, thus affecting human health. At present, there are two or three thousand kinds of genetic diseases found in medicine, and this congenital disease is extremely difficult to cure, and the incidence rate is as high as 20%. Even if there is no disease, it may be passed on to future generations through recessive genes. At the same time, the educational and psychological factors of family background may affect the future health.
way of life
A bad lifestyle is extremely harmful to people's health. For example, smokers usually have black lungs, and people who drink too much will greatly increase their chances of suffering from liver disease. Unreasonable diet can easily lead to diseases such as hypertension, hyperlipidemia and hyperglycemia, and lack of exercise can easily lead to backache. People who stay up too late will greatly increase the risk of cerebral infarction and sudden death. People who don't pay attention to hygiene are prone to breed bacteria and viruses in their bodies, thus inducing various diseases.
Nowadays, bad living habits have become the biggest killer of human health. According to statistics, the top three causes of death in China are malignant tumor, cerebrovascular disease and heart disease. Most of these three diseases are caused by bad living habits and health departments.
