Drinking beverages with a cold will not aggravate the condition, but drinking beverages with high sugar content or carbonated drinks may cause coughing and phlegm symptoms to worsen. Colds are usually caused by viral infections, which are characterized by fever, nasal congestion, sore throat, cough and phlegm, etc. Drinking beverages can replenish fluids and vitamins without aggravating the condition, but some beverages with high sugar content, especially carbonated beverages, can irritate the throat, which can easily induce cough and phlegm, and aggravate the symptoms of cough and phlegm. Cold and flu patients are advised to drink more water, increase nutrition and regular work and rest, and avoid cold, rain and overwork, etc., which will help the recovery of cold and flu.
