In adults, 37.1°C is generally not considered a fever and is within the normal temperature range. The normal temperature of the human body is between 36℃ and 37.2℃. The ways to measure body temperature include oral temperature, anal temperature and axillary temperature. The normal value of oral temperature is between 36.3℃ and 37.2℃; the normal value of anal temperature is between 36.5℃ and 37.7℃, which is 0.2℃-0.5℃ higher than the temperature of oral temperature; the normal value of axillary temperature is between 36.0℃ and 37.0℃. In addition the temperature measured by mercury thermometer, ear gun thermometer, infrared thermometer is also slightly different. Most adult temperatures are higher in the evening than in the morning because the basal metabolic rate is high in the afternoon, so the body temperature is also relatively high. If the measured temperature is higher than 37.3℃ and lower than 38℃, it means that there is a symptom of low fever. 38.1℃-39℃ is a moderate fever, and the temperature above 39℃ is a high fever, which requires prompt medical attention to clarify the cause. Therefore, the adult body temperature 37.1 ℃ is generally not considered a fever, if the body has other discomforts, it is recommended to consult a doctor in a timely manner, combined with other circumstances to make a comprehensive judgment.
