Air conditioning cold, also known as in the hot summer, due to long time indoors with the air conditioning temperature set too low, leading to the patient exhibiting various degrees of nasal congestion, runny nose, sneezing, fever, headache, dizziness, general weakness, some patients may also have nausea, vomiting and other clinical symptoms. For such patients, we must take it very seriously, promptly turn off the air conditioner or open the windows to ventilate, as this is relatively conducive to the improvement of cold symptoms, because many patients when the air conditioning temperature is too low, may accidentally catch a cold, allowing viruses and bacteria the opportunity to invade and cause the patient to develop a fever. During the fever reduction process, the patient may sweat to varying degrees. Therefore, for patients with an air conditioning cold, if sweating occurs, it is often a symptom of the fever subsiding, which is a positive sign.
