Why do people catch a cold more easily when the seasons alternate?

When the seasons alternate, many people are prone to catch a cold. Actually, it's because everyone is physically weak. For example, in summer, people wear less clothes, but in autumn, the weather gets cold, and sometimes the temperature drops suddenly. If you don't take enough clothes when you go out, you will catch a cold when the cold wind blows. Moreover, when the autumn and winter seasons change, many people are also prone to catch a cold, because spring is the season when everything recovers, and there will be some bacteria and microorganisms in the air, which will affect everyone's health.

First, because people are physically weak, the temperature drops.

Seasonal changes also mean that the temperature will change. Some people are weak and don't wear thick clothes when they go out, which is prone to health problems, especially the elderly and children. Their constitution is particularly weak, the temperature is relatively low, the wind is relatively strong, and they are easy to catch a cold. So no matter what the weather is like, you'd better prepare a thin coat when you go out, especially in June 5438+ 10. It was summer before September, and everyone wore thin clothes, but after June 5438+ 10, the temperature began to drop slowly. People often say that the autumn wind is cool, even if the sun is strong outside, the temperature of the wind is not hot.

Second, there are many bacteria and microorganisms in the air.

In spring, the sun is particularly warm, everything recovers, all kinds of flowers and branches begin to sprout, and those hidden bacteria and microorganisms will slowly spread. When people go out, these viruses in the air can easily enter the body, thus causing a series of diseases. Infectious colds are very common, so everyone should pay attention to keep warm when going out.

Three. Concluding remarks

The first symptom of a cold is sneezing. If you feel that your voice has changed when you speak, your nose is particularly uncomfortable, and you always feel that something is stuffed inside, you should take preventive measures in time, prescribe the right medicine, drink more hot water and eat more healthy fruits and vegetables.
