Our news (reporter Zhang Yiwei) recently, it is not difficult to find that many people around have caught a cold, and the number of cold patients in hospitals has also increased. The reporter interviewed relevant experts to answer questions and solve doubts for the public.

Recently, the weather in Xi’an is warm and sunny. Mr. Yang, 37, lives in Shangqin Road, Xi’an. He has caught a cold, runny nose, sneezing and always wants to cough these two days. Mr. Yang is a white-collar worker. Recently, several colleagues in the office have caught a cold. Speaking of the cause of the cold, he said that it was hot the day before yesterday. He worked at home wearing a shirt. Later, he began to sneeze and have a runny nose.

On the morning of March 3, the reporter learned from the consulting room of the Department of respiratory and critical care medicine of the second people’s Hospital of Shaanxi Province that the number of patients with colds increased compared with some time ago.

Fei Chunli, deputy chief physician of the second Provincial People’s Hospital, said that the turn of winter and spring is a season with large temperature changes and easy to catch a cold. The threat of a cold will cause many complications, such as tracheitis and bronchitis, in addition to sneezing, runny nose and cough. Large weather changes, excessive fatigue, mental tension and long-term exposure to a closed environment will all lead to a decline in immunity, giving the cold virus an opportunity to take advantage of. Therefore, the most effective and healthy way to deal with colds is to improve their immunity and reasonably match their daily diet. To improve their immunity, we should adhere to physical exercise, such as walking, running, mountain climbing, playing ball, boxing, etc., which can improve the body’s ability to resist the cold and prevent the occurrence of colds. Adequate sleep is the most basic and important health condition. Don’t let yourself get too tired. Fatigue will make the body weak and easy to be invaded by cold bacteria. High pressure has adverse effects on the body, so often keep a happy mood, and the chance of catching a cold will be relatively reduced. Pay attention to indoor temperature and humidity. The indoor temperature should be kept between 18 ℃ and 20 ℃, and the humidity should be 70%. Too high room temperature will weaken the body’s resistance to cold, so we must pay attention to the adjustment of indoor temperature. In addition, humidifier or wet towel can be used to increase indoor humidity to avoid air drying. Because in the environment with high humidity, the activity ability of bacteria will be weakened, and its infectivity will be reduced. In addition, open windows regularly every day to keep the indoor air fresh.
