How to tell your temperature without a thermometer?

Do you need a thermometer to tell if you have a fever? … The only way to know for sure that you have a fever (meaning a temp above 99 to 99.5 degrees Fahrenheit or 37.2 to 37.5 degrees Celsius) is by taking your temperature with a thermometer.

Unfortunately, your chances of accurately guessing whether or not you have a fever without a thermometer are fair at best.

If you’ve managed to dig up an old thermometer, digital and old-school glass thermometers alike should do the trick. But if there’s any indication that your old-school thermometer is cracked or broken, wrap it up in a Ziploc bag and throw it away. Mercury (a silvery-white liquid still present in some household thermometers) could leak out, and it’s toxic.

Of course, before you pop a thermometer under your tongue, you’ll want to clean it, if you have rubbing alcohol on hand, wipe down the thermometer applicator with a cotton ball soaked with rubbing alcohol to sanitize it, then rinse it off again to remove the alcohol. If you don’t have any rubbing alcohol at home, no worries—washing it off with soap and water is absolutely fine (as soap alone can break down and remove bacteria and viruses).

How to take your temperature

There are several ways to take your temperature. Each has its pros and cons.

Oral temperature: Oral thermometers are used to take a temperature in the mouth. They usually have a digital readout, beep when the reading is complete, and may even alert you if the temperature is high enough to be considered a fever.

Taking a temperature by mouth is a better option for adults than for children and babies. That’s because to get an accurate reading, you need to keep your mouth closed with the thermometer held in place for at least 20 seconds. This can be difficult for children and babies to do.

To use an oral thermometer:

  • Avoid eating or drinking 15 minutes prior to inserting the thermometer. That’s because food and drinks can alter the temperature in your mouth and affect the reading.
  • Hold the thermometer underneath your tongue for at least 20 seconds before removing it. It should be as close to the center of your mouth as possible. This may vary based on brand, so be sure to check the instructions for your specific thermometer.
  • After you get a reading, disinfect the thermometer with antibacterial soap and warm water.
