In the cold season, you are more likely to get the flu virus or catch a cold than in the warm season.

Libby Richard , an associate professor of nursing, explains why people are more likely to catch colds in the colder months.

The cause of catching a cold is not only 'cold' but also various causes caused by cold. For example, many viruses such as influenza virus and rhinovirus, which is a typical causative virus of colds, multiply faster as the temperature is lower, and the infectious period lasts longer.

In addition, inhaling cold air weakens the immune system of the airways, making it easier for the virus to settle in the airways. Also, in the cold season, the air tends to dry, and the mucous membranes of the eyes and nose become dry, making it easier for the virus to settle.

Humans

produce the vitamin D needed for immunity by being exposed to sunlight, but in the cold season when people tend to stay in warm rooms, they are less likely to be exposed to sunlight, and lack of vitamin D can also cause a cold. I will. In addition, the more you spend indoors, the more you have contact with others and the more likely you are to get the virus.

Richard says 'wash your hands often,' 'do not touch your face,' 'sufficient hydration,' 'eat a balanced diet high in vitamin D,' and 'cold.' We also recommend going out and exercising, 'activating the humidifier if you feel dry in your throat or nose,' and 'inoculating the flu vaccine.'
