You can get fast and accurate readings with digital thermometers. They are available in many shapes and sizes at grocery stores, department stores, and drug stores or Amazon.

- Oral (in the mouth)
- Rectal (in the bottom)
- Axillary (under the arm)

- Wash your hands with soap and warm water.
- Use a clean thermometer, one that has been washed in cold water, cleaned with rubbing alcohol, and then rinsed to remove the alcohol.
- Do not eat or drink anything for at least five minutes before you take your temperature. You should keep your mouth closed during this time.
- Place the thermometer tip under the tongue.
- Hold the thermometer in the same spot for about 40 seconds.
- Readings will continue to increase and the F (or C) symbol will flash during measurement.
- Usually, the thermometer will make a beeping noise when the final reading is done. If you are keeping track, record the temperature and the time.
- Rinse thermometer in cold water, clean it with alcohol, and rinse again.
