What fruits should be avoided when coughing?

When experiencing cough, avoid consuming fruits that are excessively cold or hot in nature—such as pineapple, durian, tangerines, lychee, and watermelon. Additionally, during a cough, refrain from eating overly sweet fruits—including longan, grapes, raisins, and mangoes—as these may increase both the volume and viscosity of phlegm, thereby exacerbating the frequency of coughing episodes.
