Having a thermometer at home can be very helpful, especially with the current pandemic situation. If you don’t have a thermometer yet, we highly recommend getting one, but it’s important to know how to use it properly. One of the most asked questions is how long do you hold a thermometer under your tongue? In this article, we will cover everything you need to know about using a thermometer correctly and safely.
Why Temperature Matters?
Our body’s temperature is an essential indicator of overall health. A fever is usually the first sign that our body is fighting an infection. It’s important to monitor any changes in our body temperature regularly. A digital thermometer is a convenient tool to do this at home. There are various types of thermometers available in the market, but the most commonly used is a digital thermometer.
How to Use a Digital Thermometer?
A digital thermometer uses an electronic sensor to measure body temperature. Here’s a step by step guide on how to use a digital thermometer correctly:
- Wash your hands with soap and water.
- Turn on your digital thermometer.
- Place the thermometer tip under your tongue, towards the back of your mouth.
- Close your lips and breathe through your nose.
- Keep the thermometer in place until it beeps or for the time specified in the thermometer’s manual.
- Remove the thermometer and read the temperature shown on the screen.
- Wipe the thermometer with rubbing alcohol or soap and water before storing it.
How Long Do You Hold a Thermometer Under Your Tongue?
The time you should hold the thermometer under your tongue depends on the type of digital thermometer you are using. Most digital thermometers give a reading within 10 seconds, but some models may take up to 30 seconds. Refer to the instruction manual of your thermometer to determine how long you should hold the thermometer under your tongue.
What is a Normal Body Temperature?
Knowing what is considered normal body temperature is essential. The average normal body temperature varies from person to person and ranges from 97.7°F to 99.5°F (36.5°C to 37.5°C). Generally, a body temperature of 100.4°F or higher indicates a fever, which means your body is fighting an infection. It is crucial to monitor your body temperature regularly so you can take immediate action in case of a fever.
What are the Appropriate Places to Take a Temperature?
There are several places on our body to take a temperature, but some are more accurate than others. Here are the best places to take a temperature:
- Under your tongue
- In your armpit
- In your ear
- In your rectum (for infants only)
Why is the Temperature Accuracy Important?
The accuracy of the temperature reading is critical in determining a fever. Inaccurate readings can lead to wrong diagnoses and, therefore, inappropriate treatments. A digital thermometer is the most accurate tool for measuring body temperature. It is essential to use and store your thermometer correctly to achieve accurate readings.
How Do I Ensure the Accuracy of My Thermometer?
A thermometer is only useful if it provides accurate readings. Here are some tips to ensure the accuracy of your thermometer:
- Check the user manual to understand how to correctly use the thermometer.
- Use the same thermometer consistently to monitor your temperature.
- Store your thermometer in a cool, dry place.
- Check the accuracy of your thermometer with your healthcare provider.
What is a Rectal Temperature Reading?
A rectal temperature reading is the most accurate method for infants below three months old. It is relatively invasive and uncomfortable. However, it is crucial to regularly monitor the body temperature of infants as they are more vulnerable to infections. Here’s how to take a rectal temperature:
- Cover the thermometer with a lubricant, such as petroleum jelly or lotion.
- Lay your baby flat on their stomach.
- Lift your baby’s legs by the ankles gently.
- Insert the thermometer about half an inch into the rectum.
- Hold the thermometer in place until it beeps or for the time specified in the thermometer’s manual.
- Remove the thermometer and read the temperature shown on the screen.
- Wipe the thermometer with rubbing alcohol or soap and water before storing it.
Conclusion
A thermometer is an essential tool in monitoring your body’s temperature. Knowing how to use a thermometer correctly and safely can give you accurate readings, which helps to identify any health concerns early. We recommend using a digital thermometer for its accuracy and ease of use. Remember to follow the instruction for each type of thermometer, and store it correctly to ensure its accuracy in the long term.
