How can viral cold not be infected

4hw.com.cn: every season, a cold will come suddenly. It's not terrible. What's terrible is that a viral cold can be infected. For a partner with poor physical resistance, it's a very troublesome thing to catch a viral cold. It's not only a threat to the health of the surrounding and family members, but also a very frequent illness. So how can we prevent a viral cold everyday? Let's take a look at it Now!

The main viral symptoms were high fever, which lasted for a long time, accompanied by runny nose, sneezing, sore throat, etc. The transmission way can spread the virus into the air through sneezing, coughing and talking, so as to infect others. Healthy people can also be infected with the virus by using patients' towels, washbasins or tableware.

Daily prevention of viral cold

As there is no specific treatment for cold, and once suffering from cold will have a certain impact on work and life, so prevention is particularly important. The key to prevention is to enhance resistance and prevent pathogen invasion. The main measures are:

(1) pay attention to exercise and arrange outdoor activities reasonably to adapt to the changes of environment and climate.

(2) dress appropriately, increase or decrease with climate change in time to prevent cold or overheating.

(3) control and treat chronic diseases and correct malnutrition.

(4) pay attention to indoor ventilation and avoid going to public places with crowded people and dirty air.

(5) avoid induced factors such as overwork and drunkenness.

(6) pay attention to personal hygiene and wash hands frequently.

Inducement prevention of viral cold

It is generally believed that respiratory droplets are the main mode of transmission of the virus. However, in recent years, some studies have made new claims about its inducement. The following situations are included:

(1) the cold virus' touched 'can survive for about 1 hour on the handkerchief. And the temperature of the hand is very suitable for its survival, so that the survival time of its hand can be up to 70 hours. When a cold patient blows his nose or sneezes, he will stick the virus to his hand, and then transfer the virus to places that people often contact, such as door handles, desks and chairs, telephone sets, etc. healthy people are very susceptible to infection by touching these hands or objects that pollute the virus.

(2) many experts at home and abroad have found that bad eating habits are closely related to cold. Eating too much high salt food can reduce saliva secretion, make oral mucosa edema, congestion, virus increase, easy to cause upper respiratory tract infection, and eventually lead to cold. Eating too much high sugar food can consume the body water and vitamins and other nutrients, cause dry mouth and dry tongue, lower immunity, and then induce cold. Eating too much high-fat diet, such as cream, meat, broth, etc., can reduce the anti-virus ability of immune cells in the body and easily cause cold. In order to prevent cold, we should keep away from the high salt, sugar and fat diet.

(3) the clinical observation of "sitting out" cold found that people who sat in office, in Internet bar, playing mahjong and less active had a 2-3 times higher chance of catching cold than normal people. According to reports, when the only TV Tower in an island country fails to work normally, the rate of children's cold treatment has dropped significantly. After investigation and research, in the past, children used to surround the TV all day, with little activity. Now they go back to nature to do outdoor activities, which also restores their resistance to the virus.

(4) some toothbrushes are sealed with cylinder for the cold coming out of 'brush'. Toothbrush is often in wet state, and bacteria are easy to breed. In addition to the weak individual constitution and poor resistance, people who have a cold for a long time are repeatedly infected because of the gingival wound caused by the virus by brushing their teeth.

(5) according to experts' research, taking drugs indiscriminately can lead to colds. Pharmacological experiments and clinical studies show that many drugs, especially sulfonamides, antibiotics, antituberculosis drugs, anticancer drugs, and even antipyretic and analgesic drugs (such as paracetamol) have different degrees of inhibition on the immune system of the body. Regular use of such drugs can reduce the resistance of the human body, so that people are easy to catch cold.

(6) as the saying goes, "when you are sad, you will lose your head", which shows the influence of sadness on human body. The immune function of sentimental people is easy to decrease, the ability of killing pathogenic microorganism is weakened, and the level of interferon is decreased. Accordingly, the respiratory defense function is decreased, so that the cold virus has a chance. According to the statistics of foreign scientific research data, people who often worry or worry are 3-5 times more likely to have a cold than those who are normally cheerful.

(7) smoking a cold is harmful to health, especially to the organs of respiratory system. Long term smoking also affects the endocrine system and metabolism of the whole body, so as to inhibit the immune function of the body and make people easy to catch a cold.

(8) the key to prevent the cold is to keep the indoor air clean when the cold comes out. When the doors and windows are closed and there is no carbon monoxide and other pollution sources in the room, the indoor air will also be polluted with the increase of the number of people and the extension of time. Often open the window, the exhaust gas from the human body and the smoke in the room can float away with the circulating air, which is conducive to the prevention of cold.

Common viruses include rhinovirus and coronavirus. Streptococcus pneumoniae and hemolytic streptococcus are common bacteria. The main symptoms of children with viral cold are fever, body temperature, runny nose, sneezing, coughing, good spirit, loss of appetite, sometimes accompanied by vomiting and diarrhea. A few children will have febrile convulsions. The main symptoms of children with bacterial cold are fever, especially persistent high fever, purulent nose, sore throat, mental depression, poor appetite, and some children will have high fever convulsion.
