Body Temperature

Body temperature is a measure of the body’s ability to generate and get rid of heat. The body regulates temperature by either dilating or constricting blood vessels in the skin. By dilating blood vessels within the skin, excess heat is transferred to the surface of your body where it radiates out. When it needs to conserve body temperature it constricts the vessels.

In Australia, the average normal body temperature ranges from 36.5C-37.5C

Types of thermometers

  • Disposable thermometers (placed on the forehead)
  • Eardrum thermometers (placed inside the ear)
  • Oral thermometers (placed under the tongue)
  • No-touch thermometers (measures temperature non-invasively)

After a thermometer has been used it is important that it is thoroughly cleaned with soap and warm water or with alcohol swabs. This should be done before and after each use.
