A cold, also commonly referred to as an upper respiratory tract infection, can be classified based on the type of infecting virus into common cold and influenza. Regardless of the type, patients typically experience various symptoms following the virus infection such as fever, nasal congestion, runny nose, sneezing, sore throat, coughing, and an itchy throat. For patients exhibiting these symptoms, it is generally recommended in clinical practice to drink plenty of water and avoid overly greasy foods. Certainly, consumption of alcohol and spicy foods like chili peppers should be avoided. Similarly, it is advised not to consume cold-natured foods during a cold, hence drinking alcohol is discouraged while sick.
