Why inside the ear?

The ear is the ideal place to measure the core body temperature. The core temperature is the temperature of the vital organs. The temperature in the ear correlates with the body core temperature, because the eardrum (the place where degree° monitors) and the hypothalamus (the temperature control center in the brain) have the same blood supply. Changes in this core temperature therefore affect the ear more quickly than other parts of the body.
