A body temperature between 35.0-36.0°C is not considered a low-grade fever. In defining body temperature, an axillary temperature between 36.0-37.0°C is called a normal body temperature. If the axillary temperature exceeds 37.3℃ or more, it is called a low fever. Therefore, a temperature between 35.0-36.0℃ is not a low fever, and especially a temperature below 36.0℃ is not a normal temperature. Whether there are irregularities in the measurement, such as sweat in the armpits or the thermometer is not in contact with the armpits for 10 minutes can make the measured temperature low. If the temperature is lower than 36.0 ℃ to exclude the factors of irregular operation, consider whether there is a metabolic disease, should go to the hospital for consultation.
