Forehead Thermometer Accuracy and the of other thermometer types

Body temperature is a crucial component among the health indicators. Any change in the optimal body temperature sends you signals that something is not right. As the first step towards a cure, you or your doctor will note down the body temperature. This is where the thermometer comes in. There is a mind-boggling variety in the market. Let us look at a basic few.

Digital Thermometers

These have heat sensors to identify the temperature of the body in contact. Oral, rectal, axillary or armpit are the three ways these are used. Of these, the armpit temperature is not always accurate whereas the rectal temperature is the most accurate.

A rectal thermometer is ideal for newborns to about age 3 years. For children above 3 years and adults, oral readings of temperature are also reliable if they keep their mouths closed when readings are taken.

The latest research says it is not always accurate, and it can be a challenge for children to grip the pacifier still inside their mouths.
