Using air conditioning with excessively low temperatures can cause upper respiratory tract infections. Clinically, these patients are often seen in the hot summer months and may exhibit varying degrees of fever, nasal congestion, and runny nose, with some having yellowish nasal discharge. They may also experience sore throat, coughing, and coughing up yellow phlegm. For the treatment of such patients, it is often necessary to administer appropriate heat-clearing and detoxifying medicines. Treatment should be based on the patient's body temperature; if the temperature is excessively high, antipyretic medications should be administered promptly. If the body temperature is relatively low, not exceeding 38.5°C, physical cooling methods can be used along with patent medicines to clear heat and detoxify as symptomatic treatments. These can effectively alleviate the cold symptoms caused by air conditioning.
