Immunity is the body’s own defense mechanism, which is the body’s ability to recognize and destroy any foreign invasion (viruses, bacteria, etc.), to deal with aging, damaged, dead, degenerated own cells and to recognize and deal with metabolic waste such as mutated cells and virus-infected cells in the body. Modern medicine refers to the system in which the body performs this function as the immune system. For millions of years, humans have lived in an environment that is both suitable for survival and fraught with danger, and they have survived and acquired extraordinary immunity. Thus, immunity is the product of a biological evolutionary process. The term “immunity” was first used in the Chinese medical book “Immunity Formula” of the Ming Dynasty, which means “immunity from epidemics”, that is, the prevention and control of infectious diseases. Immunity can be classified according to the way it is acquired: 1. Innate immunity, which is present in human beings since birth. For example, swine fever spreads quickly among pigs, but has nothing to do with humans. This is because humans are not born with this disease; 2. Acquired immunity, which is acquired naturally after birth in the course of life, or passively with artificial assistance. Manifestations of low immunity A body with low immunity is susceptible to infections or cancer; an overactive immunity can also produce harmful results to the body such as triggering allergic reactions, autoimmune diseases, etc. For various reasons, the immune system cannot play its protective role properly, and in this case, it is very easy to invite infections such as bacteria, viruses and fungi, so the most direct manifestation of low immunity is easy to get sick. Because of frequent illnesses, the consumption of the body is increased, so there is generally weakness, malnutrition, depression, fatigue, reduced appetite, sleep disorders and other performance, sickness, injection and medication will become a daily routine. Each illness takes a long time to recover, and often recurring. In the long run, this can lead to poor physical and mental development, as well as major diseases. The underlying cause is low immunity or immune deficiency. When the body’s immune function is dysfunctional, or the immune system is not sound, the following problems will recur: – recurring colds, recurring tonsillitis, recurring asthma, recurring bronchitis, recurring pneumonia, recurring diarrhea …… so it must not be underestimated. Often feel fatigue – work often can not be energetic, a little bit of work to feel tired, go to the hospital examination also did not find any organic lesions, rest for a period of time after your energy and relief, but last a few days, fatigue again. Cold and flu constantly – cold and flu become your daily routine, the weather becomes slightly colder, cooler, it is too late to add clothes you sneeze, and the cold and flu to experience a long time to cure. Wounds easily infected – which part of the body accidentally cut, within a few days the wound will be red, swollen, and even pus, normal people can quickly heal, but you therefore have to drag a long time; or you have a certain part, such as a small painful and itchy boil on the buttocks, and after a few days the head grows again. Delicate intestines – eating an ordinary dish at a restaurant outside, other people are safe and sound, while you vomit and have diarrhea. Why do you have poor resistance The immunity of the human body mostly depends on genetics, but the environment also has a great influence, such as diet, sleep, exercise, stress, etc.. Among them, diet has a decisive influence, because some food components can assist in stimulating the immune system and enhancing immunity. A lack of these important nutrients can seriously affect the body’s immune system function. How to improve immunity Code 1: balanced nutrition To eat healthy, and thus strengthen the body’s immunity, the most important thing is adequate nutrition and balanced, most people eat, the first consideration is whether it is convenient, eat full, good to eat as a priority, only a few people will be “balanced nutrition” as a priority. The principle of nutritional balance is actually very simple: consume about three to six servings of staple foods, two glasses of milk, four to five servings of eggs, fish, meat and beans, at least three servings of vegetables (dark green vegetables are preferred), two servings of fruits, and two to three tablespoons of fats and oils every day. Especially most people, vegetables and fruits are obviously not enough, sometimes not even a portion of intake, therefore, to remind themselves that every meal must eat vegetables and fruits, and diet diversity, do not always eat certain specific food, which is easy to create nutritional waste. Code two: three more, drink more water, more exercise, more rest Drink more water: can promote the body’s metabolism, so adults must take about 2,000 ~ 2,500 ml of water every day. More exercise: do at least thirty minutes of aerobic exercise every day, such as: walking, swimming or cycling, etc., to maintain a healthy body and maintain the ideal weight, in order to have plenty of energy to fight the virus! More rest: more and more people are staying up late to work, on the Internet or enjoy the night life. However, staying up late can lead to lack of sleep, resulting in a decline in immunity. So the time to sleep to sleep, the time to get up to get up, in line with the body’s physiological clock, adequate sleep and rest, in order to maintain the body’s immunity, to fight the virus! Code three: three less, less sweets, less fat, less alcohol, quit smoking There are some foods that will reduce immunity, it is best to eat less, otherwise it will not only interfere with the vitality of immune cells, and even inhibit the formation of lymphocytes, so that the immune function is impaired. Eat less sweets: sweets can affect the production and activity of white blood cells, reducing the body’s ability to resist disease. Therefore: do not gamble on your health because of a momentary desire for food and drink, which is very scratch! Less fat: eating too much oil, especially taking in too much bad fat, will hinder the ability of immunity, so that the body’s immune cells become lethargic, and can not function. It is recommended to reduce the amount of cooking oil and high fat, high salt intake, especially fried things and fatty meat eaten as little as possible. Drink less alcohol: Drinking alcohol can seriously weaken the normal function of various immune cells, and also affect the function of the liver and pancreas. In addition to alcohol, cigarettes, coffee, drugs, etc., will not only reduce the body’s immunity, but also harmful to the human body, so refuse to deal with these things is definitely the best policy. Quit smoking: medical evidence, smoking when the body’s blood vessels are prone to spasm, local organs reduce blood supply, nutrients and oxygen supply is reduced, especially the respiratory mucosa is not supplied with oxygen and nutrients, the ability to resist disease is also reduced. Code four: cultivate a variety of interests to maintain high energy and mental health: a wide range of interests will benefit people, not only to cultivate the body, and can assist in the treatment of some mental illness. Treat stress well, see it as an inseparable part of life, and learn to reduce stress moderately to ensure a healthy, good state of mind. A smile to cure all diseases, with a positive outlook on life, a moderate expression of stress, more close to nature, more laughing, but also a variety of immune system enhancement methods of the wonderful partner oh! A few simple and practical ways to improve immunity One, with the help of sleep sleep and human immunity is closely related. A good night’s sleep can lead to a significant increase in the number of both types of lymphocytes in the body. The body produces a sleep factor called cytosolic acid during sleep, which leads to an increase in white blood cells, active macrophages, and enhanced liver detoxification, thereby eliminating invading bacteria and viruses. Second, maintain optimism optimism can maintain the body in an optimal state, especially in today’s society, people are facing a lot of pressure, huge psychological pressure will lead to an increase in hormonal components that have a suppressive effect on the human immune system, so vulnerable to colds or other diseases. Third, limit drinking alcohol not to drink more than 100 ml of low white wine, not more than 250 ml of yellow wine and not more than 1 bottle of beer per day, because alcohol has a negative impact on every part of the human body. Even if drinking wine can lower cholesterol, it should be limited to one glass per day, excessive drinking will cause great damage to the blood and heart and other organs. Fourth, participate in exercise, 30 to 45 minutes a day, 5 days a week for 12 weeks, the number of immune cells will increase, and resistance will increase relatively. Exercise as long as the heartbeat is accelerated, a walk after dinner is very suitable. Five, supplemental vitamins every day to properly supplement vitamins and minerals. Experts point out that the body’s weapons against foreign aggression, including interferon and the number and vitality of various types of immune cells are related to vitamins and minerals. Sixth, improve the body’s ecological environment with microecological agents to improve immunity has a long history of research and use. Research shows that the beneficial flora represented by Bifidobacterium intestinalis and Lactobacillus have broad-spectrum immunogenicity, which can stimulate the division and reproduction of lymphocytes responsible for human immunity, and can also mobilize the non-specific immune system to “eat” all kinds of disease-causing foreign microorganisms, including viruses, bacteria, chlamydia, etc., to produce a variety of Antibodies, improve the body’s immune system. Seven, foot massage fluid can enhance immunity, the central depression in the heart of the foot is the kidney meridian Yongquan point, the palm of the hand depression is the pericardial meridian Laogong point, if you often rub the heart of the foot, you can make the legs and feet strong, and a healthy gait. The specific method of rubbing the heart of the foot is: sitting cross-legged, left hand holding the left toe, right hand palm surface rubbing the right foot, back and forth for 100 consecutive times. Change feet, also back and forth continuous rubbing 100 times, both morning and evening. Hot water to wash the feet by the way after rubbing the heart of the feet, the effect will be better.
