Why is it not easy to catch a cold in winter but easier to catch a cold in spring?

The temperature is low in winter, so people wear thick clothes. In addition, most people stay indoors in winter, even people who go out will soon enter a warm place, and the measures to keep warm are very good. Moreover, in winter, people's awareness of warmth is higher, and they will pay more attention to daily life. On the contrary, in spring, the temperature will be unstable, especially when spring and summer alternate, and the temperature difference between morning and evening will be great. Some people feel hot at noon, take off their clothes when they are thick, and don't keep warm in time after the temperature drops at night. Others don't like the trouble of taking clothes. They will wear thin clothes when they go out in the morning, and they are easy to catch a cold.

When the temperature changes rapidly in spring, people's immune and defense functions will decline. This season, with strong winds and dry climate, bacteria are more likely to breed. People's contact will also increase. The more people go shopping and have a spring outing, the greater the chance of infection. Drink plenty of boiled water in spring, pay attention to keeping warm and eating, and it is best to do more exercise to keep healthy.
