Because the tongue is a place in the human anatomy that has a very stable body temperature. Other places in the anatomy that are use are, '1 the armpit, and '2 into the anus. Modern technology has superceded a thermometer , for a 'ray-gun'. The 'ray-gun' is pointed at the forehead, and it reads the body temperature. For a healthy human, the body temperature is 37.5 oC . This can range between 37 oC and 38 oC . Outside these limits ;- 36 oC ; HYPOTHERMIC * Cold/Frostbite and liable to die) 39 oC ; HYPERTHERMIC * Hot/fever (convulsions) Even when you exercise and feel hot, you body temperature will not be above 38 oC.
Taking your temperature under the arm (axillary) is generally lower than taking it under the tongue (oral). The oral temperature is usually considered more accurate and reliable, as it reflects the core body temperature more closely. Typically, the difference can range from about 0.5°F to 1°F (0.3°C to 0.6°C), with the oral temperature being higher. Therefore, if you measure your temperature under the arm, it is expected to be lower than the reading from under the tongue.
Measuring body temperature by keeping thermometer under the tongue is a convenient standardfor measuring one's body temperature. Other places used for keeping the thermometer includethe armpit and the rectum.

A thermometer is kept under the tongue to measure the body's core temperature accurately. The blood vessels under the tongue provide a good reflection of internal body temperature, making it a reliable location for temperature measurement. The mouth is also a convenient and non-invasive site for taking temperature readings.
There are a net of blood vessels close to the surface under the tongue and this gives a true reading of the temperature of the blood (and hence the body).
Put a thermometer under your tongue and close your mouth tightly.
