Disadvantages of immunity to the human body 15

Immunity is the body's own defense mechanism, which is the body's recognition and elimination of any foreign body (virus, bacteria, etc.) that invades from outside; Ability to process aging, damaged, dead, denatured own cells and to recognize and process mutant and virus-infected cells in vivo. Modern immunology believes that immunity is the body's physiological response to recognize and exclude "aliens". It is the immune system that performs this function in the human body.

Immunity can be divided into non-specific immunity and specific immunity.

Immunity can be divided into 1 according to the way in which it is obtained:1. Congenital immunity is something that people are born with.

For example, swine fever spreads quickly in pigs, but it has no chance with humans. This is because humans are not born with this disease; 2。Acquired immunity is acquired naturally in the course of life after birth, or passively obtained by artificially assisted methods.

Manifestations of weakened immunity].

Immunocompromised bodies are susceptible to infections or cancer; Abnormal immunity can also have harmful consequences for the body, such as triggering allergic reactions, autoimmune diseases, etc.

The immune system cannot play a protective role normally due to various reasons, and in this case, it is very easy to incur bacterial, viral, fungal and other infections, so the most direct manifestation of low immunity is easy to get sick. Because of frequent illness, the consumption of the body is aggravated, so there are generally physical weakness, malnutrition, mental atrophy, fatigue and weakness, decreased appetite, sleep disorders and other manifestations. Every time I get sick, it takes a long time to recover, and I often do it back.

In the long run, this can lead to poor physical and mental development, and can also easily induce serious diseases.

The underlying cause is a weakened or unsound immune system. When the body's immune system is dysfunctional, or the immune system is not sound, the following problems will be reversed: cold, tonsillitis, asthma, bronchitis, pneumonia, diarrhea ......So don't take it lightly.

Reproduced.

If the immunity is excessive, there will be rheumatic diseases. If your immunity is low, your body will decline, and you will often get sick.

Immunity is important for the human body. If the body's immune function is weakened or not sound. It is very easy to incur bacterial, viral and fungal infections.

Getting sick easily. Even a small cold will do the opposite. So immunity is really important for the human body.

Then it is necessary to improve and strengthen one's own immunity.

Immunity is the body's own defense mechanism, the body's ability to recognize and destroy any foreign body that invades from outside, to deal with aging, damage, death, degeneration of its own cells, and to recognize and process mutant cells and virus-infected cells in the body.

1. Help the body resist the invasion of viruses and bacteria.

Immunity is a defense system that rejects foreign antigens and foreign substances, which is a plate-energy response of the body. When the body is infected by bacteria and viruses, the immune system will jump out in time, mobilize lymphocytes and white blood cells to fight bacteria and viruses, engulf bacteria that are harmful to the body, and prevent bacteria from invading the body.

2. It can solve some garbage cells.

Our body is metabolizing all the time, and there are new cells to multiply, and some old cells are eliminated. Under the condition of ensuring the normal functioning of the body, immunity can remove old and crippled cells, which are old or dead cells. The immune system automatically recognizes old cells and then engulfs them to keep the body functioning properly.

3. It can prevent cancer cells.

As the name suggests, cancer cells are normal cells with mutated genes, and the immune system can automatically recognize these mutated cells and directly eliminate or kill them. In addition, immunity can also prevent cancer cells from multiplying in the body. In fact, there are cancer cells in everyone's body, when the immune system is strong, it can directly engulf or kill the cancer cells, and when the immune system is lowered, the cancer cells will multiply in large numbers and eventually show up in the form of cancer.

Improving immunity and keeping the body from getting sick or less sick is the biggest benefit. Once people's resistance is very weak, all kinds of diseases intrude, it is easy to solve small illnesses at every turn, it is easy to get seriously ill for a long time, and it is not easy to get seriously ill, which is a very serious problem. Therefore, it is very important to improve the person's own immunity.

1. Reduce various diseases. Because the improvement of immunity can ensure the normal function of the immune system, promote endocrine stability, and reduce various bacterial infections. Some people lack training for a long time, do not cultivate good exercise habits, and do not pay attention to dietary control, resulting in a plummeting immunity, causing a variety of viral and bacterial infections, and also causing systemic manifestations, which have a great interference with people's living conditions.

2. Better mental state. If the resistance is not strong, then the spirit has always been in a state of depression and decadence, and life is very vulnerable to external interference. Therefore, everyone should pay attention to enhancing resistance and ensuring good sleep and work, which has a very good recovery effect on the body.

3. Prevent symptoms such as dizziness and dizziness. If the resistance can be properly enhanced, dizziness and weakness of the limbs can often be prevented, and various body functions will become more active. Therefore, we should pay attention to the improvement of resistance, strengthen exercise every day, enhance the ability to prevent diseases, and improve the symptoms of physical weakness.

Immunity is a physiological function of the human body, which relies on the human body to recognize "self" and "non-self" components, so as to destroy and reject antigenic substances entering the human body, or damaged cells and tumor cells produced by the human body itself, so as to maintain the health of the human body.

A state that resists or prevents infection by microorganisms or parasites or other undesirable biological invasions.

We all know that only when the body has a strong immunity will our body be healthy, strong, and less prone to getting sick. So, what factors affect the body's immunity? Let's find out. <>

There are still many factors that affect the immunity of the human key bucket body. First of all,It has a lot to do with diet. Many people have poor eating habits in their lives.

Tips. If you want to improve your body's immunity, you must eat a reasonable and balanced diet. Also, don't smoke or drink.

Then, develop a good lifestyle habit and get 8 hours of sleep every day. Don't stay up late, don't overwork, and combine work and rest. <>

Then, you should do proper exercise and don't sit sedentary for a long time. Try to set aside half an hour a day to exercise. Exercise can not only improve the body's ability to avoid air infections, but also make our bodies stronger and stronger.

Then, maintain an optimistic and comfortable mood, and don't be nervous, stressed, anxious, etc. for a long time. The above is just my personal opinion.

It is influenced by environmental factors, dietary factors, work factors, physical factors and Bizen genetic factors. Therefore, in our daily life, we must eat more fresh vegetables and fruits, because these foods can strengthen our resistance to violent force.

The body's immunity will be affected by diet, genes, physical fitness, exercise, and the external environment.

Bring even in the culture of science and technology.

How important is human immunity? Take last year's epidemic as an example, which gave us a new understanding of immunity.

In daily life, whether it is an adult or a child, people always mention this word when they suffer from common diseases such as colds and fevers. Exempt.

Epidemic force refers to the body's ability to resist foreign invasion and maintain the stability of the internal environment; In other words, it is the ability of the human body to resist various diseases.

Force. For the new crown pneumonia epidemic that has affected many countries last year, professionals initially thought that children and young people were not easy to be infected.

to identify the general susceptibility of the population. Eventually, the researchers came to a conclusion: people with low autoimmunity are more susceptible to infections and are autoimmune.

People with strong strength are less likely to develop severe disease, and even if they are infected, the probability of being infected** is greater.

Why do infected people show different symptoms? It depends on two aspects, the strength of one's immunity and the number of viruses infected.

Measure. Most young patients have mild symptoms precisely because they have better immunity. Their immune cells are intact and well-functioning.

Well, there will be a certain amount of resistance to viruses invaded by the outside world. This is not the case with the elderly. As people get older.

The body's function begins to deteriorate, which means that the immune ability of immune cells decreases, so the body's overall ability to resist bacteria and viruses is also.

will go down with it.

If older people also have other underlying medical conditions, their immune system is weaker and they are more susceptible to infections from the environment.

Disturb. Immunity can protect us from the invasion of pathogenic microorganisms, and it is an important barrier of the body's immune mechanism.

It is important to protect the human body from being attacked by "enemies" such as bacteria and viruses.

Of course, this does not mean that young people can rest easy. No matter how good the immunity of young people is, bad lifestyle.

For example, staying up late for a long time, smoking, drinking and other bad lifestyle habits will lead to immune dysfunction, which will bring advantage to pathogenic microorganisms. opportunity.
