Colds can be categorized into many types, such as from the perspective of traditional Chinese medicine, into cold-induced colds and heat-induced colds. Cold-induced colds generally occur in winter. At the onset of such colds, it is usually not recommended to consume watermelon. This is because watermelon itself is considered a "cold" fruit, and conditions like cold-induced colds are often caused by exposure to cold winds leading to symptoms like nasal congestion and runny nose. Consuming watermelon at the onset of a cold-induced cold might worsen upper respiratory tract symptoms. On the other hand, heat-induced colds often occur in summer and are marked by symptoms such as sore throat, varying degrees of fever, and cough. In these cases, it is appropriate to eat some watermelon. Watermelon is nutritionally valuable and has cooling and heat-relief effects. Thus, for patients suffering from an upper respiratory tract heat-induced cold in the summer, consuming watermelon is suitable.
