It is easier to catch a cold when the seasons change. Why are people more likely to get sick when it is cold and hot?

People are particularly susceptible to colds when the seasons change, especially when the weather changes from hot to cold. We often hear concerns from family members: It’s getting cold, remember to wear more clothes to prevent colds. ?When the weather gets colder or hotter, more people will catch a cold, especially those with poor health.

1. Why do people tend to catch colds easily when the weather is cold or hot?

The cause of a cold in the human body is that viruses in the air enter the body and destroy the body's immune system, thus inducing a cold. There are many viruses in the air where humans live. Under normal circumstances, the human body's own immune system can eliminate these viruses. However, once the weather changes, once a person catches cold or rain, or is overworked, the body's immune system will decline, and viruses will enter the body and cause colds.

2. How should we prevent colds in our daily life?

First of all, pay attention to weather changes. Check the weather forecast frequently to prevent the weather from getting colder. You must wear more clothes when it's cold, don't take off your clothes casually when it's hot, and be sure to cover yourself with a quilt when you sleep at night. The purpose of doing these things is to avoid catching a cold.

Secondly, pay attention to your diet. In daily life, we must eat a reasonable diet and pay attention to balanced nutrition. A good body requires nutritional supply. If our daily diet cannot supply the body with the capabilities it needs, it will lead to frailty, and frailty will lead to illness. We should eat more vegetables and fruits, eat less spicy, greasy, and cold foods, and pay attention to the mix of meat and vegetables.

Third, strengthen physical exercise. People who like to exercise will have a particularly good physique and are less likely to get sick. People who insist on exercising have good physical fitness and strong immunity, so viruses are less likely to invade the body and colds are less likely to occur. In daily life, we must strengthen physical exercise to make our body in great shape.

Fourth, develop good work and rest habits. People who often stay up late have particularly weak immunity and are prone to catching colds. We must develop the habit of going to bed early and getting up early, not staying up late, or using mobile phones before going to bed, so that we can get adequate rest.
