Why do colds occur frequently in hot and cold seasons?

The weather began to turn from hot to cold. It's cold in the morning and evening, and it's hot at noon, so people who wear less clothes are prone to catch a cold and have a fever. The change of seasons is accompanied by the change of hot and cold, and the common sense of indoor ventilation becomes extremely important, because at this time, you will catch a cold if you are not careful. The common cold, also known as "cold", is usually caused by a cold or alternating cold and heat. The onset is faster. At first, there will be itching, dry throat or strong burning sensation.

After a few hours, you will have a stuffy nose, sneezing, drooling and runny nose. Sometimes, there will be poor breathing, tears, dull taste, hoarseness and cough. Generally speaking, acute viral pharyngitis with no fever or only low-grade headache is usually caused by adenovirus, rhinovirus, influenza virus or respiratory virus. Symptoms of the disease include itchy and burning throat, rare cough, sometimes accompanied by fatigue and fever, obvious congestion and edema in the pharynx, and obvious pain when speaking or swallowing food.

The common cold can be cured by taking some cold capsules, such as Guankang and Niuhuang Jiedu tablets, paying attention to rest and drinking hot water for more than a week. Viral pharyngitis is usually caused by viruses. It's better to catch a cold and sweat. Need to take some anti-inflammatory drugs and antibiotics, such as penicillin, cephalosporin, roxithromycin and so on to treat inflammation. If cough and throat congestion are serious, it can be taken together with throat moistening drugs, such as Fritillaria cirrhosa, chicken cough syrup and Radix Isatidis granules.
