The body temperature of adults is usually measured by axillary temperature, and the normal value is about 36~37℃, but you can also choose to measure the oral temperature and rectal temperature, and the specific normal range value is slightly different. Normal human body temperature is relatively constant and can fluctuate within a normal range, due to the different ways of measurement, the body’s normal body temperature value will also have some differences. The most common ways to measure body temperature in adults include axillary measurement, oral measurement, frontal temperature measurement and anal measurement, among which axillary measurement is the most common. Axillary temperature measurement is easy to operate and convenient, relatively speaking, it is more suitable for adults to use, and the normal value of axillary temperature is about 36~37℃. Oral temperature measurement is more strict on the sterilization of thermometers, and is less commonly used in clinical practice. The normal value of oral temperature is around 36.2~37.2℃. Frontal temperature measurement is one of the most commonly used infrared detection methods at this stage, the biggest disadvantage is that it is greatly affected by the environmental temperature, and its normal value is about 36.2~37.2℃. Rectal temperature measurement can directly understand the temperature of the body, due to the inconvenience of use, generally not applicable to the use of adults. For some other factors can not use the armpit measurement or oral measurement of adults, only choose rectal measurement. The normal value of rectal temperature is around 36.5~37.5℃. When the body temperature is abnormal, it is important to go to the regular hospital in time.
