The normal value of body temperature varies depending on the measurement method. Axillary body temperature is 36-37℃, oral temperature is 36.3-37.2℃, and anal temperature between 36.5-37.5℃ are all normal values. Human body temperature is relatively constant, rectal temperature is the closest to the human body temperature, but most people measure axillary temperature or oral temperature mainly. It is important to keep quiet when measuring body temperature. If the axillary temperature exceeds 37℃ or the oral temperature exceeds 37.2℃, it means that the body temperature is high and there may be fever, which should be combined with the patient’s symptoms, such as headache, fatigue, muscle pain, nasal congestion, runny nose, cough, etc. It is recommended to go to the hospital for routine blood tests, C-reactive protein tests, chest X-ray and other tests. Fever is a common clinical symptom, which can be seen in a variety of diseases, need to go to the local fever clinic in time, and should be under the guidance of the doctor for treatment and medication.
