More and more people are catching colds accidentally during the fall and winter seasons, and many people are even catching colds constantly for three days. What exactly is the reason why it is often easy to catch a cold? Of course, many people know that easy to catch a cold is caused by low body immunity. Then how exactly is it?

Deficiency of the body by evil

In Chinese medicine, a person's vital energy is weak, the table is loose and the coup is loose, so if you are not careful, you will easily feel the wind evil and catch a cold. It is important to know that "the wind evil attacking people, no matter where they feel than the internal return to the lungs." Especially for those who have Yang deficiency, Yin deficiency or after illness, it is easy to catch a cold when you feel the wind.

Cold in the back of the head

A cold on the back of the head is very likely to cause a cold. The skin on the head is more dense than other parts of the body and is rich in blood vessels and lymphatic vessels. When the body exercises a lot or after taking a bath or washing hair, the back of the head easily sweats. The body heat evaporates through the back of the head, so if you get cold, wind and cold will easily invade your body and cause a cold. You should also pay attention to keeping the back of your head warm.

Overexertion

Prolonged overexertion can lead to a decrease in immunity and ability to resist viruses, making it easy to catch a cold. People who work under stress are recommended to pay attention to the combination of work and rest, and to strengthen the diet and nutrition to ensure the body's immunity and resistance to avoid frequent colds.

Low immunity

When the body's immunity is low, it is easy to catch a cold with a little wind or once you come into contact with the virus that causes a cold, so you should pay more attention to improving your immunity.

Therefore, you should not take the cold lightly, especially when it is caused by human coronavirus, and you should seek medical attention. In addition to human coronavirus, adenovirus can also cause various inflammatory diseases in the body.

Respiratory syncytial virus

Respiratory syncytial virus is most common in children under the age of 2. Infection with respiratory syncytial virus can easily cause serious respiratory illness and can be repeated. Adults who are infected with this virus usually have a milder form of upper respiratory illness.

Influenza viruses

The main viruses responsible for influenza are influenza and parainfluenza viruses. Influenza viruses spread easily among susceptible people, mainly through droplet transmission, and the scope of infection and injury caused by them is very large, and the virus is constantly mutating and can be repeated.

Sadness

People who are often sentimental are also prone to reduced immunity, and their ability to resist viruses and kill pathogenic microorganisms is greatly weakened, and their respiratory defense system is easily damaged, making them susceptible to colds. Therefore, people who often catch a cold can see if they are often sad and sentimental.

Other causes

In addition to the above reasons, people who have poor indoor air circulation, people who like to smoke, and people who like to keep their toothbrushes sealed are all prone to catching colds.

Scientists have discovered through research that shiitake mushrooms contain mushroom ribonucleic acid, which can stimulate human reticulocytes and white blood cells to release interferon, which can destroy viruses in the body and thus strengthen the body's resistance to influenza virus. In addition, shiitake mushrooms have the function of destroying viral activity.
