A fever can often be a good sign.

Generally, fevers happen when your immune system is fighting off infections such as colds, coughs and ear infections. At the first sign of attack, the body’s defenses launch infection-fighting chemicals into the blood. These chemicals also affect the body’s thermostat, which is located in the brain and called the hypothalamus.26,27

To take your temperature and help with managing fever, there are different types of thermometers you can use:24

  • Digital.
    These thermometers are quick and accurate and can be used for taking temperatures orally, rectally and under the armpit.
  • Ear.
    These digital thermometers are inserted into the ear and can only be used to take ear temperatures. They can be more expensive than other types of thermometers.
  • Strip.
    These are placed against your forehead, and show the temperature of the skin, but not the body. They are not very accurate.
  • Glass.
    There are two types of glass thermometers; those that contain a coloured alcohol to measure the temperature, or the more old-fashioned type which contains mercury. The use of mercury glass thermometers is not recommended, as mercury can be highly poisonous.

If you have a fever but are fine in every other way, then you may not need to do anything aside from making sure you are properly hydrated.24,28
