During summer, due to the hot weather, air conditioning is often used. If the air conditioning is set too cold, it might cause some people to catch a chill, leading to various symptoms such as nasal congestion, runny nose, sneezing, coughing, and sore throat.

For patients with such symptoms, the first step is to check if they have a fever and identify any other accompanying clinical symptoms. If the patient simply has a dry cough, it may be appropriate to use some heat-clearing and detoxifying traditional Chinese medicines. Then, depending on the nature of the cough, central cough suppressants should be used as symptomatic treatment. Generally, recovery can happen within a week under such treatment.

In cases of a summer cold where the patient starts to produce phlegm in the later stages of coughing, it is then necessary to use some anti-inflammatory medicine for symptomatic treatment, as this may indicate a possible bacterial infection.

(The use of medications should be done under the guidance of a professional doctor.)
