Four cornerstones of keeping healthy: balanced diet, moderate exercise, quitting smoking and limiting alcohol. Mental health.
Extended data:
Keeping healthy is a gradual process, which will be influenced by the evolution of medical knowledge and practice, as well as personal strategies and some organizations.
First, self-care strategy.
Personal health depends on some information about physical condition observed by oneself, and it is also related to the adjustment made by individuals for physical health. These include personal actions to prevent diseases or reduce the effects of diseases, as well as food safety during hand washing and bathing with soap, brushing and flossing, food storage, preparation and handling.
Information obtained from these daily life observations-such as sleep patterns, exercise, nutritional intake and environmental characteristics. -It is helpful for personal decision-making and action (for example, "I didn't sleep well last night and decided to change my pillow tonight." The diagnosis and treatment plan goes to the clinic (for example, "A patient notices that if his shoes are tight, his left heart will feel uncomfortable and may need diuretics to reduce the water in his body."
Second, diet.
There are seven kinds of nutrients needed by human body to maintain health: carbohydrate (whole grain), protein, fat, minerals, vitamins, cellulose and water.
A balanced diet and moderate exercise are very important for people. A balanced diet refers to choosing the right amount of food to provide various nutrients and appropriate calories to maintain the growth of body tissues, enhance resistance and achieve moderate weight. When eating, you should eat according to the proportion of "diet pyramid" and drink enough water every day to promote health.
A balanced diet can make the body function normally, help to resist diseases, make people feel energetic and keep their ideal weight at all times. To achieve the ideal weight, the most effective and sustainable way is to maintain a healthy diet and moderate exercise. Eating more fried and too sweet or salty food may lead to obesity, high blood pressure and high cholesterol, which is harmful to people's health.
The three principles of a healthy diet are: eat a variety of foods, avoid overeating, and pay attention to balance, so as to absorb all kinds of needed nutrients.
A healthy diet includes food safety and hygiene. Whether buying or handling food, cooking or eating out, we should pay attention to avoid getting sick or food poisoning, which has a negative impact on health.
Third, exercise.
Exercise strengthens muscles and circulatory system. Exercise can maintain or enhance physical fitness and promote health, such as the core and squat exercises discussed the most in 20 18. But if you don't exercise for a long time, your muscles will degenerate or even shrink.
Fourth, the role of science.
Health science is a branch of science concerned with health. It has two main directions: studying the problems related to human body and health, understanding the operation of human body (and animals), and applying this knowledge to promote health, prevent and treat diseases or other physical or psychological injuries. Health science can be divided into many fields, including biology, biochemistry, physics, epidemiology, pharmacy and medical sociology.
Apply health science to apply knowledge of health education, bioengineering, biotechnology and public health to further understand health-related problems and promote people's health.
The role of verb (verb's abbreviation) in public health.
Public health can be described in the following words: "The science and art of preventing diseases, prolonging human life and promoting health through systematic efforts of society and organizations, public and private sectors, groups and individuals."
Public health is based on population health analysis, focusing on events or diseases that threaten community health. The people to be discussed can be as small as a few people, or as large as all the people on all continents (such as plague). Public health has many sub-fields, but they are usually related to epidemiology, biostatistics and medical care. Environmental health, group health, mental health and occupational health are also related fields of public health.
