How to take your temperature

Whatever type of thermometer you end up using, make sure you’ve cleaned it properly according to the instructions. This is usually done with cool, soapy water, but if you’re using an ear thermometer you need to use a dry cloth. As different thermometers work in different ways, and getting it right affects the accuracy of the reading, it’s really important to always start by reading the manufacturers’ instructions, even if you’ve had a similar thermometer before. If you have any further questions, consider asking a pharmacist.

Tips for getting the best reading: Fever aside, there are other factors that could affect the reading you get from a thermometer. It’s worth checking it when you feel well, so you have an idea of what’s normal for you, as it can vary slightly. If you’re checking your temperature multiple times a day to track progress of a fever, try to keep the conditions consistent. For example, excess clothing, bedding, having eaten or drunk recently, or outside weather conditions can all have an effect.
