Fever, meaning heat, is a symptom that manifests itself in the form of fever, and eating ice cream with a fever is generally not recommended. During a fever, the patient’s body temperature increases to varying degrees. However, the elevated body temperature will reduce the enzyme activity of the gastrointestinal tract, and symptoms such as poor appetite or gastrointestinal discomfort will occur. Ice cream belongs to the cold and stimulating food, for people who are usually in good physical condition, although it can satisfy the momentary taste, the fluctuation of the body temperature will also have a certain effect on the immune response, which is not conducive to the recovery of the disease. For people with poor physical quality and poor gastrointestinal function, the sudden temperature drop in the gastrointestinal tract after consuming ice cream may cause nausea, vomiting, abdominal pain, diarrhea and other stress reactions, and in severe cases, there may be severe vomiting, dizziness, shock and other adverse consequences. Therefore, it is not recommended to consume raw, cold and stimulating food during fever, but can eat some mild, easy to digest and easy to absorb food, and appropriate hydration to promote the recovery of the disease. If you have any unexplained fever, you should go to the hospital in time to see a doctor to clarify the cause of the disease and then target treatment. Do not blindly use medication on your own before going to the doctor, so as not to cover up the condition and affect the doctor’s judgment.
