Why clinical thermometer is placed under tongue or armpit?

Answer 1

so that the air from breathing does not pass over it and cool it thereby giving an incorrect reading
To give a true reading of inner body heat.
Because the intense heat of our body is present under our tongue so that we can measure our whole body temperature .
The underside of the tongue has the most bloodflow and is more accurate than any part of the mouth

Answer 2

Clinical thermometers are placed under the tongue or in the armpit because these areas give a good indication of the body's core temperature. The mouth and armpit are areas where blood vessels are close to the surface, making temperature readings more accurate. Placing the thermometer in these areas helps provide a reliable measurement of body temperature.

Answer 3

well in order to get an accurate reading of bodily temp you need to get the thermometer inside your body... now there are a couple other methods of taking temp such as in the ear which requires a special more expensive thermometer or or course rectally... and that would not be comfortable. so that is why under the tongue has become the standard form of checking temp it is simple and pain free and the most inexpensive. not to mention very accurate.

Answer 4

this is probably the most accurate place to judge the heat of your body.

If you look at the underside of your tongue you will see a number of blood vessels very close to the surface. By putting the right thermometer under your tongue and closing your mouth you will get a very good reading of your body temperature.

Answer 5

It is proven that taking the body temperature under the tongue and armpits is more accurate than any other area of the body.

Ayraayra: Actually the most accurate core temp is taken rectally, although the new thermometers they use usually in PEDS is the temporal thermometer which has been proven to be fairly accurate also and less invasive.
There are lots of blood vessels under your tongue and because your tongue is closer to the core of your body it give a more accurate temperature reading.
When you stick a thermometer in your mouth, obviously it gets wet. When moisture evaporates off of a wet surface, the temperature drops slightly. Breathing will increase the rate of evaporation (and, therefore, the amount the temperature drops). To get the most accurate reading, the thermometer needs to be under the tongue so it will be protected from the air current produced by breathing.

Answer 6

Rectal temperature is the most accurate, however how many of us want to have it taken that way? Also, this method does have a slight chance for injury to the rectum or of losing the thermometer into the rectum.

Next best is oral temperature. To take an oral temperature, which is almost as reliable when done correctly, make sure the person has not had anything to eat or drink within the last 10 minutes. Place the thermometer under the tongue so that it sits down in the small "pouch-like" area on either side of the piece of tissue that holds the tongue down, (the frenulum).

The person must hold their mouth closed and keep the thermometer in place for a certain period of time. If you have a digital thermometer, it will tell you when it's "done". If you are using an old "Mercury thermometer", the thermometer must stay under the tongue for at least a minute to 2 minutes.

Answer 7

The three most common places to take body temperatures using a clinical thermometer is:-

Under the tongue,

Under-armpit and

Rectally

Under the tongue is not used for babies or small kids in case they bite the thing. (It's made of glass!)

Rectally is considered the most accurate of the three.

Answer 8

To measure the temperature in that warm place. If you keep your mouth open, or put it somewhere else, it is likely to measure the temperature more of the outside air than the temperature of your body.

Answer 9

The thermometer is place under the tongue because blood vessels run close to the surface and the thermometer can pick up a temperature that is most accurately the real body temperature. You also have sort of a "pocket" when the tongue covers the thermometer.

Answer 10

It gives a true reading of inner body heat, besides for the anal one or the arm pit one. I love the ear one, simplicity and its fast, digital read.
