The alternation of seasons with high and low temperatures is the easiest to catch a cold. What methods can help prevent colds?

It is easy to catch a cold when the seasons change or the temperature changes greatly. When the weather is cold, people's pores will shrink, thus resisting the invasion of cold air. When the weather is hot, the pores will relax and sweat to dissipate heat. But when the temperature changes greatly and the weather is hot and cold, the self-regulation of the human body can't keep up, and you may catch a cold. Therefore, when changing seasons, we should pay attention to increasing or decreasing clothes in time and strengthening exercise. On a hot summer night, some young people have the habit of sleeping with the window open, which is easy to catch a cold due to the breeze. Don't think you are young and strong and neglect your health. In addition, when people adapt to a new place, their resistance will be reduced due to the sudden change of environmental temperature.

The fast-paced city life sometimes makes people too busy to have a good meal and rest. Excessive fatigue can lead to decreased immunity. If people encounter influenza virus at this time, they will be easily infected. Sometimes, the stress brought by busy work will affect people's mood, and then affect the immune system, leading to decreased resistance. So when you are busy, try to keep a regular diet, try to find more time to rest, and don't choose bars, drinking and other relaxation methods. Work and rest regularly every day, and your illness will be relieved a lot.

If you are ill, you must take medicine on time. Be sure not to carry it hard. It is often a small problem, because it becomes a serious illness if it is not treated in time. However, you must consult your doctor about how to take medicine and dosage, because all cold medicines are compound preparations now. Taking too much medicine will cause liver damage, and taking too little medicine will not achieve the therapeutic effect. In particular, the dosage of children should not be confused with that of adults. Children must take special drugs. If you take other drugs during a cold, such as drugs for heart disease or high blood pressure, you must inform your doctor in advance.

Whether in offices, shopping malls, cinemas or other indoor places, if the crowd is too dense, it will increase the risk of catching a cold. Once someone sneezes, others are in danger of catching a cold. If the working environment is difficult to change, you should consciously go out more and participate in outdoor activities as much as possible. When people are crowded, try to wear a mask and pay attention to cleaning after returning home to avoid family contact with bacteria. Some drivers and friends drive for a long time in a relatively closed space. If the air quality is not improved, it will easily affect their health. At this time, this requires a suitable air purifier.
