Why The Ear?

Research indicates that the ear is an ideal site for taking body temperature. The eardrum shares blood vessels with the hypothalamus, the part of the brain that regulates body temperature. Therefore, the ear is an accurate indicator of internal body temperature. Since ear thermometers are designed to receive information from the ear, it is a very safe method for measuring temperature and can be used on children of all ages.
