Is it true that people who haven t had a cold for three or four years really have a good immune syst

Yes, because they often insist on exercising, have good living habits, maintain a reasonable diet, and do not stay up late often, they greatly improve their immune system and ensure good health, so they will not catch a cold.

Yes, it is very common to have a cold because you are infected with a virus, but because it has a very good immune system and has good immunity to viruses.

Yes, such people have a stronger body and stronger immunity, which can resist germs very well.

This statement should also be correct, because colds are a good way to boost the body's metabolism by repairing its functions. It is possible to remove some of the worse cells. Promotes better cell production.

This statement is true, because when we have a cold often, our immune system will become stronger with regular exercise.

This statement is obviously wrong, it is precisely because the immunity has improved a lot that it will not catch a cold, not that the immunity will decrease if you do not catch a cold for a long time.

This is very true because your immune system has not evolved effectively, and if your immune system does not work for a long time, your immunity will be lowered.

That's right, if we often catch colds, we will only make our own immunity lower and lower, and we often get some diseases.

This statement is not right, and it is very one-sided, not catching a cold can only say that your resistance is very strong, and it has nothing to do with anything else.

Of course, no, because people who are in good health will not catch a cold, so it is impossible to reduce immunity.

Of course, this statement is incorrect, because if you don't catch a cold, you have a particularly good immunity.

Is it true that "it is not good to not have a cold for a long time, and once you get sick, you may get seriously ill?" "I myself think so:

First, if you don't get seriously ill, it doesn't depend on whether you haven't caught a cold for a long time. If only this were the case, when I arrived at the hospital, the doctor said: How long have you not had a cold?

A month, half a year, a year, if: yes, the doctor will not say: you have to pay attention to not catching a cold for a long time is not good, once you get sick, it is a serious illness.

I believe that the sick person was suddenly angry, thinking that this hospital is not lightly ill.

Second, the fact that a person can't catch a cold varies from person to person. Some people have beautiful weather and good things, of course, they also pay more attention to their diet and have good living habits, that is, they have fewer colds. Some people are born with a sick look, and they have to catch a cold from time to time, but they are not too sick, which is not to say that they have a cold and produce antibodies or anything.

So far, there is no vaccine for the common cold in the world, only the flu vaccine.

Third, judging from the current medical knowledge, it is basically certain that there is no inevitable causal relationship between getting a serious illness and getting a cold. After all, the human body has a set of immune mechanisms, only the body is in sub-health for a long time, and the immune mechanism is not effective, the body is easy to get sick, if you continue not to pay attention to the body, the body's immune system will completely fail, and the serious illness is really coming.

Colds are not associated with a serious illness at all. People often say that "it's not good to not catch a cold, but you have to have a cold to detoxify, otherwise, once you get sick, it will be a serious illness", which has no scientific basis, which is an extremely misleading misunderstanding. I have never had a cold, I have not seen a doctor, I have not taken medicine or injections, and now I am in my 60s, and all indicators of my annual physical examination are normal.

Colds are caused by various reasons, simply put, "poor immunity, weak resistance", and various bacteria and viruses invade. Therefore, there is no causal relationship between a cold and a serious illness.

It's true, once you get sick, it's very serious, because you don't usually have a sense of maintenance.

It's not true, this can only show that this kind of person has good immunity, and the resistance is relatively strong, which also means that the body is better.

In fact, people who often have a cold or fever have lower immunity, so they are at greater risk of other diseases.

This question should be divided into two to see, whether there is a problem with immunity, this will not be discussed for the time being, first of all, we have to see whether a person has other diseases, other aspects are very healthy, then this person is said to have good physical fitness, that is, immunity is relatively good, so it is not easy to catch a cold, this I have personally experienced. From the time I can remember my father to his death, I hardly saw my father suffer from any illness, but he died of a sudden heart and brain attack in his later years. I am different from my father, since I was a child, I had a poor physique, almost 4 times a year before the age of 40, so my physical fitness is very poor, although I have become associated with Chinese Qigong, my body has been greatly improved, and now it is 27 years old, and the cold has decreased from the original four times a year, and almost rarely has a cold, even if there are three pairs of Chinese medicine, I have never been to the hospital, that is, I have a physical examination once a year, there is no major problem, and my physical fitness is on the upper level in the same age.

Whether the cold has anything to do with immunity, of course, it is related, because colds often cause a lot of complications, such as bronchitis, pneumonia and other diseases, modern also have gastrointestinal colds and other natures, to put it bluntly, the cold is a kind of inflammation, inflammation will cause fever, it will produce similar symptoms of colds, so traditional Chinese medicine classifies it as virtual fire or real fire, so colds have become the most common disease, so it has a certain relationship with immunity.

Yes, it is not normal to have no fever for many years.

I've had a fever only once in more than 50 years of my life.

There are two types of people who have not had a cold or fever for many years.

The first is when the body's immune system is not functioning properly.

The second type is very good physical fitness.

I'm 48 years old, I've never taken any medicine, and I've never lost a single drip. Every year on November 12, I will catch a cold, and I can go into the sauna and steam for half an hour.

It's also possible that the immune system is too strong.

I don't think that's the case, but not catching a cold for a long time is a sign of strong immunity, because only poor immunity will be invaded by viruses every day.

It may be true, but this view is also normal, so people with such a constitution should pay attention.

I feel that it is not as long as I have been without colds, but rather the emergence of immunity, because only poor immunity is the cold that is invaded every day.

I think it's fake, because it's not easy to catch a cold, which means that the person's physical fitness and immunity are very strong.

I think it's fake, because it's not easy to catch a cold, and this person's body quality and immunity are very good.

If you don't catch a cold for a long time, your immunity is still poor, and you are prone to cancer?

Many people believe that people who have not caught a cold for a long time are more likely to develop cancer because their immune system is not active, but is this statement credible? Hello everyone, I'm Dr. Yan, and today we're going to talk about this question.

First, let me tell you about the relationship between frequent colds and immunity, why do we catch colds? When the human body is invaded by pathogenic microorganisms, our immune system will start our immune response in time, through cellular immunity and humoral immunity, to prevent pathogenic microorganisms from harming our collective, if the microorganisms are not eliminated in time, with the advancement of time, inflammatory cells will release some small active ingredients, these active ingredients can cause cough, fever, body aches and other symptoms, so cold symptoms are also a manifestation of the body's self-protection. If it is a person with good immunity, these pathogenic microorganisms will generally be eliminated at an early stage, and generally will not cause the symptoms of a cold, and even if there are symptoms, it is very mild, so some people have not caught a cold for many years, which is generally a manifestation of strong immunity.

Second, if you have poor immunity, most of them will have symptoms of a cold every time they are infected, so the number of times they get sick is more. Let's take a look at whether people who don't often catch colds are more likely to get cancer, and studies have found that our normal human body will produce some mutated cells every day, so some researchers have found that there are about 3,000 to 5,000 mutated cells, so these cells will be found and captured by our immune system in time, and removed in time. If the immunity is low, some mutated cells may not be detected and eliminated in time, and some may develop into bad lesions.

Third, strong immunity is not easy to develop tumors, which is a result of medical research. But some people don't get sick often, think that they have strong immunity, and don't have any physical examinations, and they don't go to the hospital easily if they feel uncomfortable, and as a result, if he suffers from a tumor, most of them are hard to carry, and finally become the advanced stage of the tumor.

Finally, let me tell you how to improve immunity, the first is to maintain a happy mood, the second is to keep exercising, the third is to get enough sleep, and the fourth is to eat a balanced diet. To summarize the content of this lesson, people with strong immunity are not easy to catch colds and tumors, but they must have a physical examination on time, and if they are unwell, they must go to the hospital in time, do not carry it, if they have tumors, we can detect them early, and the prognosis for early detection is good.

People who have not caught a cold for a long time indicate that their immunity is relatively strong, and such people are generally in better health. The chance of cancer is also smaller. But you should also get regular medical check-ups.

In fact, if you don't catch a cold for a long time, this is a manifestation of strong immunity, because if our immunity is relatively poor, if we accidentally catch a cold, it is very likely that we will suffer from a cold and wind cold, and it may be difficult to heal. Therefore, we must strengthen exercise in our daily life to improve our immunity.

No, on the contrary, the child's immunity is very strong, and it may also be that the child has been staying in a familiar environment and has not been exposed to new antigens, so he has not caught a cold.

No, it means that the child's resistance is particularly good, and he has also received a very good nutritional supplement in life, so the child will not get sick often.

Of course, the immune system is not good.

The immune system is designed to fight against all kinds of external and internal agents.

Colds are mostly caused by viral infections, and if you have strong immunity, you will not catch colds often, because in the early stage of virus invasion, the immune system will clear these viruses and will not allow them to multiply in large numbers.

Illness is only possible if the immune system is weakened, or if the virus is particularly aggressive. Since the common cold is caused by a common virus, frequent colds indicate a weakened immune system.

Exercise should be intensified to build resistance.

In fact, there are pathogens that invade the body through various ways all the time, so there is an immune system fighting against it all the time. If an individual has more symptoms than others in the same environment, it can be said that his immune system is not very strong, because every time he is infected, other people can kill the pathogen at a lower state of immune response activity, and this person has to adjust the immune activity to a high level to destroy the pathogen. But after each infection, the immune system will make a file of the pathogen, and the next time you come to the same pathogen, you can quickly clear it.

I don't understand what you said about hidden ** infection, if it means that it is indeed infected by a pathogen, and there are pathogens in the body that survive and replicate, but the individual's subjective feelings are relatively flat, then it cannot be said that the immune system is relatively sluggish, and it can be understood that for the body, the pathogen at this time is in a state of "low activity", and the incubation period is one of them. If the "activity" of the pathogen is high, the immune activity is also high, so fever, nasal congestion, etc.; If the activity is low, the immune system will directly kill it or continue to maintain its current state and leave it untreated.

Another problem is that cold symptoms are caused by the immune system, and it is the immune system's response that makes people feel uncomfortable, not the virus itself;

Preface: There are many people who have not been sick or cold for several years, so they feel that their health is very good. If you often catch a cold, your immunity is relatively low, and if you don't catch a cold for a long time, your body's immunity is better.

So everyone's health is better, and we shouldn't worry too much. There are many people who think that if you don't have a cold or fever, it is a precursor to a serious illness, but in fact, there is no scientific basis for this statement. In daily life, we must maintain a regular schedule and have good eating habits, so as to prevent diseases from entering the mouth.

Many people are very worried that if they don't catch a cold for a long time, it will affect the body's immunity, but if they don't catch a cold, it just means that the body's immunity is better, so don't worry too much. There are many people who think that if they don't catch a cold, their body will develop other major diseases, and there is no scientific basis for this statement. If you are in good health, then you will not catch a cold.

There is also no fever, which is a very normal thing. After we have a cold, we must drink plenty of water and get enough sleep, so that our body can return to its normal state.

For us, the body's immunity must be very important. If the immunity is relatively low, then when the weather turns cold, it is easy to catch a cold and fever, and it lasts for a long time. Therefore, we must do a moderate amount of exercise, and we should not spend all our time on our mobile phones, which not only easily cause myopia, but also cause a certain degree of damage to the spine.

At the same time, you need to ensure more than 8 hours of sleep every day, go to bed early and get up early, and develop good living habits, so as to prevent diseases from coming to your door. Then after any disease, we must prescribe the right medicine, we must seek the help of a doctor in time, so that the body can return to a normal state as soon as possible.
