38.8℃ is not a high fever, but a moderate fever, but it needs to be examined by a hospital promptly and treated accordingly. High fever refers to the axillary body temperature between 39.1℃ and 41℃, including 39.1℃ and 41℃. However, 38.8℃ is close to hyperthermia, which can easily cause panic, headache and other uncomfortable symptoms. It is necessary to apply acetaminophen or ibuprofen and other drugs to do antipyretic treatment in time under the guidance of a doctor, and do blood tests to determine the cause of fever. Patients should pay more attention to rest and eat light, easy-to-digest food, such as white porridge, noodles, vegetable soup, etc. Food that is cold, greasy, spicy and stimulating should be forbidden, and fresh vegetables and fruits should be eaten appropriately.
