The normal temperature of the human body is roughly between 36.2°C and 37.5°C, depending on the measurement method chosen. Human body temperature is usually measured by oral, axillary and rectal methods, and the normal values of body temperature obtained by these three methods of temperature measurement are different. The normal value of oral thermometry is 36.2℃～37.2℃, the method of use is to place the mercury end of the sterilized thermometer under the tongue of the person being examined, close the lips tightly and stay for 5 minutes and then take it out to check the temperature. The normal value of axillary thermometry is 36℃～37℃, the method of use is to hold the mercury end of the thermometer in the armpit and take it out to check the temperature after 10 minutes. Rectal thermometry normal value is 36.5 ℃ ~ 37.5 ℃, the use of the method is to be measured to take the side lying position, the round blunt end of the anal thermometer coated with lubricant, slowly inserted into the anus up to half of the thermometer, placed 5 minutes after taking out the view temperature. It is recommended that if the measurement of temperature is not within the normal value range, it is necessary to go to the hospital in a timely manner, to clarify the cause of the disease, under the guidance of the doctor for treatment.
