Why does a cold last for a long time to get better?

Poor constitution, **inappropriate. It is generally believed that colds are caused by an upper respiratory tract infection and are transmitted through breathing and droplets. In recent years, researchers have discovered many little-known aspects of cold infection:

1. Hands are the main way to spread colds Cold viruses can survive for 1 hour on handkerchiefs and 70 hours on hands. When people with colds blow their nose or pick their noses, the virus sticks to their hands and spreads through handshakes, towels, tables and chairs, etc. The prevention method is to wash your hands frequently, and do not use your hands to mold your nose and eyes.

Respiratory and droplet transmission are secondary routes of transmission of colds. Second, the foot is susceptible to cold The foot is the farthest away from the heart, and the blood volume of ** is relatively small, so it is more sensitive to cold, which reduces the resistance of the upper respiratory tract. When the temperature drops below 7, the foot will dry, which will reflexively cause the nasal mucosa to constrict.

Some people call the foot the "second heart" of people, and to prevent colds, it is necessary to do a good job of keeping the feet warm. 3. The "three highs" diet is susceptible to colds Foods that are too rich, such as chicken, duck, fish, delicacies and other high-fat, high-protein, high-sugar diets will reduce the body's immune function. The new way to prevent colds is to eat a combination of meat and vegetables.

4. Prefer salty food and are prone to colds Salt can reduce saliva secretion and reduce lysozyme in the mouth. Due to the osmotic effect of sodium salt, the function of epithelial cells is inhibited, which reduces the secretion of anti-sulfants such as interferon, and the virus takes the opportunity to invade the mucous membrane of the upper respiratory tract and induce colds. 5. Improper use of drugs is easy to catch a cold Antipyretic analgesics, antibiotics, sulfonamides, anti-tuberculosis drugs, anthelmintic drugs, anticancer drugs, etc. have different degrees of inhibition effect on the body's immune function, and the abuse of these drugs will reduce the body's ability to resist diseases and make people easy to catch colds.

6. Sorrow is easy to catch a cold As the saying goes: "If you are sorrowful, you will have a white head." "Sentimental people are prone to reduced immune function, weakened ability to kill pathogenic microorganisms, decreased interferon levels, and weakened respiratory defenses, giving cold viruses a chance.

7. Nervous and susceptible to colds A medical expert observed more than 400 unemployed, unemployed, divorced and other mentally stressed people that they were more susceptible to colds than people who were not nervous, because the antiviral substances such as nasopharyngeal interferon and nuclease were significantly reduced, and local immunity was reduced. 8. Colds that do not heal for a long time are related to toothbrushes Some toothbrushes are sealed with cartridges and are often in a humid state, and germs are easy to breed and multiply. In addition to weak constitution and poor resistance, people who have not been cured of colds for a long time are repeatedly infected by the virus through gum wounds caused by brushing.

9. There is no specific medicine for colds The Common Cold Research Center of the University of Wales in the United Kingdom has concluded that there is no specific medicine for colds through a 10-year study of 5 million pounds, because there are more than 200 kinds of cold viruses in the world, and the difficulty of finding a special medicine for colds can be imagined. 10. Sleep can cure colds In recent years, American scholars have discovered that cold patients produce a substance called "cytosis avoidance" when they have a fever, which has the effect of improving immune function. This substance is also produced when people are asleep, so it is recommended that cold patients sleep more to improve immunity, and the cold will be cured without medicine.

Yes. The reaction of a cold is due to the fact that there are many types of viruses that cause colds, so it is not uncommon for another viral infection to occur soon after one viral infection has been cured. Therefore, a person may have repeated colds in a short period of time.

If you want to prevent colds, you should strictly quit smoking, drink more hot water, rest more, live and rest regularly, develop good living habits and eating habits, do a good job of personal protection, strengthen exercise, and enhance physical fitness, so that you can reduce the number of colds.

It can only be thought that the general situation will not be invaded again by the same cold virus, but "cold" is a general term for n kinds of upper respiratory tract infected by n kinds of viruses and bacteria, so it is possible to catch a cold again in the short term. If it's not the virus next time, and you don't have enough resistance, you risk catching a cold again.

I feel that when I get rid of the cold, my body will develop a certain resistance. Therefore, it is not possible to catch a cold again in a short period of time after a cold, so pay attention to rest. After a cold, the body produces antibodies to this type of virus, and this type of cold will not appear again for a short time.

If it is a viral cold, it will develop immunity after it is cured, so it will not catch a cold again in a short time. If you don't take precautions, you will relapse. During the cold period, the body is weak and the immunity is weakened, and if you do not take precautions or adjust your diet and rest during the recovery period, you may relapse.

Hardly. Because the flu virus is different every time, if you have a cold, you just form antibodies to this flu virus, if it is not this virus next time, and you do not have enough resistance, you may get a cold again. If you don't pay attention, you'll really catch a cold.

This is not necessarily, after a cold is good, you must pay more attention to cold protection and warmth than usual, otherwise there will be a second cold. Advice: There are many causes of colds, and the types of viruses and bacteria are also different, so it is possible that the cold will be followed by another cold.

There are many causes of colds, and the types of viruses and bacteria are also different, so it is possible that a cold may be followed by a cold with other germs. If you are infected with other cold viruses, you may also experience cold symptoms. Be sure to keep warm after you get better, and exercise more to enhance your resistance.

The getting worse of colds is associated with a weakened immune system. After the occurrence of a cold, it is mainly manifested as symptoms of pain and discomfort all over the body, fever, nasal congestion, runny nose, headache and other symptoms, which are easy to recur. Pay attention to rest, reduce activities, drink more warm water, avoid cold, usually exercise appropriately, enhance physical fitness, improve immunity, you can take some cold medicines, such as mepopseudo hemp tablets.

Eat plenty of zinc-containing foods, exercise properly, and get enough sleep.

At this stage, most of the patients with fever and cold seen in medicine are hot. According to the basic theory of traditional Chinese medicine, this is often related to eating too much spicy food, greasy food and drinking, staying up late, emotional tension, etc., and is also known as "easy to get angry". If there is fire in the body, it is easy to lead to the invasion of cold and evil qi, resulting in the production of colds and producing "cold and fire" syndrome, which is the most common type of fever and cold at this stage.

Some patients have repeated colds, often suspect that they are weak, and go to the hospital to consult what supplements to take, and some people simply advocate eating Korean ginseng, wild reishi and other tonics. In fact, among people who constantly catch colds, there are not many people who are really weak, and the vast majority of patients are due to the "fire" in their bodies.

The phenomenon of "fire" mainly includes: after the wind and cold, through treatment, although the symptoms are alleviated, the heat in the body has not been cleared, and the yin and yang of the human body have not yet been restored. After the first recovery of the cold, it was not well regulated.

There are many people who can't wait to start eating chicken, duck, fish, spicy food, drinking alcohol, and often staying up late when they catch a cold, which usually causes a hot revival. The basic theory of traditional Chinese medicine believes that in the middle and late stages of fever, "meat will be restored", and "more food will be lost", in other words, after suffering from fever, the human body has not yet recovered, and it will begin to eat at will, which is easy to make the disease continue. Whether it is the residual heat ** is not purified or the fire is resurrected, there is fire in the body, and the body is very easy to cause the invasion of evil qi again and cause another fever and cold.

People who have repeated colds often have a bad habit of taking medicine haphazardly after a cold. Many people think that anyone can cure a fever and a cold, and they can buy some medicine at the pharmacy at will, or find a spare medicine at home and take it. The most common of these is drug abuse.

In fact, in the early stage of a cold, viruses are dominant, and taking antibiotics causes most of the harm. Abuse of Chinese herbal formulas is also very common. At present, the best Chinese medicine prescriptions for colds on the market are mostly heat-clearing and detoxifying, which have a better effect on wind and cold.

The fever and cold are divided into two kinds: wind chill and wind heat, different types of colds ** to take medicine is completely opposite, if the wind cold cough accidentally ingested the medicine that clears the fire, it will worsen the condition.

It may be because the body's immunity is low, and if you don't pay attention to it, you will get a cold again, or it may be that the bacteria have suffered an infection.

It may be because the constitution is relatively weak and the resistance is not good. You can go to the hospital for a check-up, first get rid of the cold, and then see if there is a lack of vitamins or something.

It may be caused by low immunity in the individual's body, so you should drink more water, exercise more, and eat more green fruits and vegetables to enhance your physique.

Most colds are probably caused by germs. Then all the symptoms are the response of the body's immune system to fight cold germs. Such as:

In case of fever, the rate of reproduction of cold germs in high temperatures decreases, which is conducive to the control of the body's immune system.

Sneezing is to expel germs from the nose and mouth.

Coughing, because there are too many bacterial corpses and immune cells in the throat, unable to breathe, these impurities are expelled from the body or inhaled into the stomach to digest them.

There are scientists in the United States who have tried to recover from the infection of cold germs to the destruction of germs by the body's immune system, and it generally takes about two weeks to recover health. Of course, if you are malnourished during this period and cannot provide enough nutrients to the immune system, the time may be longer, or the condition may worsen.
