4. What are the factors that affect health?
The World Health Organization reports that health and longevity depend on the following factors:
Self-care accounts for 60%
Genetic factors account for 15%
Social factors account for 10%
Medical conditions account for 8%
Climate factors account for 7%
The report emphasizes the importance of strengthening health education, health protection and health promotion, and advocates self-care. This new concept requires people to shift their attention from paying attention to treatment to active preventive health care, from relying on medicine to taking the initiative to control their own health.
5. Are people who are not sick healthy?
"Healthy and disease-free" is a general, one-sided and incorrect formulation, which should be analyzed in detail.
One is the health care and diet structure that people usually pay attention to; Pay attention to proper arrangements for their work, study, rest, entertainment and sports; Pay attention to their psychological state and social interaction. They are cheerful, energetic, energetic and have strong resistance to diseases. Such people can be said to be healthy people.
There is also a person who has not found any specific diseases through various examination methods in the hospital, but always feels weak, irritable, insomnia, palpitation and other discomfort. Without taking medicine, these feelings may disappear on their own, but they cannot be completely eliminated. For this kind of person, we call his body in a "sub-health state", that is, what some scholars call "the third state of the body" or "the gray state", which is very important for health and disease. On the surface, the harm to the human body is not great, only in the reduction of physical ability. In fact, its potential threat cannot be ignored. It is often the precursor of some chronic diseases, such as diabetes, cardiovascular and cerebrovascular diseases, cancer and so on. Some scholars call this kind of people sub-healthy. One of the fundamental reasons for this situation is "not having a correct understanding of health and losing due vigilance against various factors that threaten one's health". In addition, due to the complexity of various relations in modern society, mental stress, work pressure, environmental pollution caused by modern industrialization, unqualified diet structure and other factors. This requires the dissemination of health knowledge, so that everyone can understand health and know the ways and means to get health.
For those who think that "no disease is health", we should help them have a correct understanding and take the initiative to get a truly healthy life.
6. What essential nutrients are needed for human health?
Nutritionist's research proves that it can maintain the normal growth and development of human body; Provide energy for life, work and sports; Substances that maintain health and repair tissues are collectively called "nutrition". The substance that supplies nutrients to the body is called "food". The various nutrients contained in food are called "nutrients". Every nutrient has its special function in nutrition, so every nutrient plays an irreplaceable and very important role in human body. Generally speaking, the main functions of nutrients are to form trunk, repair cells, supply heat energy and regulate physiological functions. Nutrients exist in food. After long-term unremitting efforts by nutritionists, it has been made clear that the essential nutrients for human body can be divided into seven categories: 1 carbohydrate, 2 fat, 3 protein, 4 minerals, 5 vitamins, 6 water, 7 dietary fiber or crude fiber, with more than 250 kinds of ingredients.
7. What does a reasonable diet include?
We eat every day, the purpose of which is to absorb the nutrients and energy we need through food, form our own organization, supply energy for our work, and maintain normal growth and health. A diet that can achieve these functions is called a "reasonable diet" or a "balanced diet".
The price of a reasonable diet is not necessarily expensive, and expensive dishes are not necessarily reasonable. For a healthy person, the formulation of a reasonable diet is related to national conditions and historical traditions. According to China's national conditions, the Standing Committee of Nutrition of China adopted the Dietary Guidelines for China Residents in April 2007 1997, and put forward the following opinions on the reasonable diet of China residents:
1) There are various foods, mainly cereals.
2) Eat more vegetables, fruits and potatoes;
3) Eat milk, beans or their products every day;
4) Eat proper amount of lean meat such as fish and eggs, and eat less fat and meat oil;
5) Balance food intake and physical activity, and maintain a proper weight;
6) Eat a clean low-salt diet;
7) Avoid smoking and drinking, and it is best to quit smoking and drinking;
8) Eat clean and hygienic food instead of spoiled food.
8. Why is fatigue an "invisible killer"?
Nowadays, urban life tends to be high-speed, fast-paced and tired-as a social civilization disease, it is the product of tension. Because of its wide coverage and serious harm to health, it has attracted more and more attention from the medical community.
Fatigue is defined in medicine as a condition caused by the excessive operation of organs or organisms, which is manifested as the decline of human function and general discomfort. Fatigue can be divided into four types: physical fatigue, mental fatigue, morbid fatigue and psychological fatigue.
According to the data, there are three kinds of people in China who are most likely to die of fatigue.
The first category is "scholars", who are intellectuals in schools and scientific research units. Due to long-term fatigue and years of research work, fatigue accumulation is aggravated, which leads to serious dysfunction of organs and tissues, decline of human immune function, and various physical and mental diseases and physical diseases follow one after another. The so-called break down from overwork.
The second category is "migrant workers". Due to excessive fatigue, low living conditions and poor medical security, the mortality rate is on the rise.
The third kind of people "company family", foreign-funded companies and various types of private companies are developing rapidly now, and a large number of company families serve them. Some of them are irregularly overworked, overtired, exhausted and often die suddenly.
Medicine believes that there is always a development process from "overwork" to "illness", which is the gradual accumulation of fatigue. The key to prevent overwork from becoming a disease is to find the degree of fatigue sensitively. Everyone has the experience and feeling of excessive fatigue. Feeling tired is not a bad thing, because fatigue is a signal to protect human health and is a warning to people that it is time to rest, otherwise there will be big problems! Unfortunately, some people are not very sensitive to this signal, but they don't care, and it's too late to regret it.
At present, there are many people in this state in society, and more than 65% managers in enterprises have different degrees of "fatigue syndrome". On the surface, they are all disease-free, but in fact their bodies are in a very fragile "balance" state. British scientist Ferich said: "People who are overtired are chasing death." . In the mid-1990s, scientists predicted that "karoshi" was spreading to China. The phenomenon of young and middle-aged people dying young in recent years (such as Wang Junyao, pictured) also shows that young and middle-aged people in China should care about their own health, prevent fatigue from becoming an "invisible killer", enhance their health concept, strengthen their awareness of self-care, and cherish their health and life.
9. What is "drug-induced disease"?
The role of any drug is dual, especially many commonly used drugs are chemically synthesized, which not only have the "treatment" effect on human diseases, but also have the side effects of harm to human body. Therefore, if drugs are used improperly, the incidence of this side effect will continue to rise, which will lead to new diseases in the human body, which is called "drug-induced diseases". For example, some antibiotics, if used improperly, will damage the kidneys, liver, audio-visual nerves and so on. Some diuretics can cause hypokalemia; Some sleeping pills can make people dependent on such drugs. Even with Chinese medicine, this situation still exists, but it is relatively rare. For example, digitalis has been poisoned by digitalis. It can be seen that when using drugs to treat diseases, we must follow the doctor's advice in terms of dosage and interval, and we must not make our own decisions and use drugs at will, resulting in serious consequences.
10, what is "preventive treatment"?
This sentence comes from China's ancient medical masterpiece Huangdi Neijing. It means don't wait until you have a disease to treat it, but to prevent it when there are no symptoms. This paper fully explains the two important tasks of medicine, namely, treating diseases and preventing diseases, and points out that the latter is more important and has more practical significance today.
In recent decades, chronic non-communicable diseases (malignant tumors, cardiovascular and cerebrovascular diseases, diabetes, etc. ) has increased, and the mortality rate has obviously increased, which has caused a great threat to human life and health. Medical research on chronic diseases shows that although the above-mentioned diseases mostly appear in middle-aged and elderly people, the increasing trend of risk factors often appears in adolescence. Once these diseases are formed, their treatment effect is limited, but the degree of death and disability is high and the treatment cost is high. Therefore, preventive measures should start with teenagers.
The research on the national key projects in the Ninth Five-Year Plan shows that investing 1 yuan in disease prevention can save the medical expenses and the rescue expenses of 100 yuan in 8.5 yuan. When you are not sick, actively taking various measures to protect your health can prolong your health time, improve your quality of life and bring great benefits to your family and society.
In order to control the occurrence and development of chronic non-communicable diseases, it is very important to vigorously implement the policy of putting prevention first. Let this sentence of Chinese medicine be deeply rooted in the hearts of the people.
1 1. What is immunity? What are the immune functions of human body?
What diseases can abnormal immune function lead to?
Immunity is the body's ability to resist diseases. It is a physiological function of the body to identify and remove foreign bodies and maintain the balance and stability of the internal environment.
The human immune system is a very large and precise system composed of immune organs, immune cells and immune molecules.
The functions of exemption are mainly divided into the following categories:
1, immune defense function: it can resist the invasion of pathogenic microorganisms and toxins and protect the health.
2. Self-stabilization function: constantly remove damaged, aged and degraded cells to maintain the stability of the internal environment of the body.
3. Immune monitoring function: identify, kill and remove mutant cells to prevent cancer.
Abnormal immune defense function: allergic reaction occurs when the reaction is strengthened; When the reaction is too weak, it is immunodeficiency, and the resistance is extremely low.
Abnormal homeostasis: If overreaction occurs, normal cells will also be removed, leading to self-tissue damage and autoimmune diseases, such as rheumatism, rheumatoid disease and lupus erythematosus.
Abnormal immune monitoring function: mostly manifested as low immune function, prone to cancer.
