Chengdu people wore short sleeves yesterday and cotton-padded clothes today. Why is it easy to catch a cold when the temperature drops suddenly?

According to the weather report in Chengdu, the weather in Chengdu is only 15.3℃, which is nearly 2.2℃ lower than yesterday. Coupled with light rain during the day, the temperature plummeted, making Chengdu people change from short sleeves yesterday to cotton-padded clothes today. As a result, the weather suddenly rained and cooled down, which made many people unprepared and caught a cold before getting dressed. Why is it easy to catch a cold when the temperature drops suddenly?

Why is it easy to catch a cold when the temperature drops suddenly? First, the temperature plummeted and the body could not adapt in a short time. If you don't add clothes in time, you are likely to catch cold and cause a cold. In addition, when the weather suddenly turns cold, not adding clothes in time leads to a cold. Therefore, if the weather suddenly cools down, we must add clothes to keep warm in time to avoid catching cold.

Second, when the body catches cold, gets caught in the rain or is overworked after the sudden drop of temperature, the local defense function of the whole body or respiratory tract is disordered, which can not effectively remove pathogenic microorganisms, leading to the rapid proliferation of viruses or bacteria, thus causing colds. Especially for the elderly or children, their airway defense function is relatively poor, and they are more susceptible to the influence of climate and seasonal temperature, causing colds.

Third, when the temperature drops suddenly, the immunity will also drop, especially the visceral function will become dull because of hypothermia, and the food cannot be completely digested, which will affect the absorption of heat and cause various discomforts. When the body temperature drops, the amount of enzyme secretion will also decrease, so that the heat source of immune cells is insufficient, the activity becomes dull, and the resistance also decreases, thus causing a cold.

Generally, the onset of a cold will be more urgent. When a cold happens, patients will have sneezing, runny nose, stuffy nose and other uncomfortable symptoms. In order to avoid catching a cold, everyone must pay attention to the weather changes. It's getting cold, so we should increase or decrease clothes in time. At the same time, pay close attention to your physical condition. Once we catch a cold, we should actively treat it. At ordinary times, we should maintain good eating habits, do more exercise, enhance physical fitness and improve immunity.
