A thermometer is an essential medical device to have at home. This is especially true for families with young children, as thermometers help parents quickly determine whether their child has a fever. With so many thermometer options available today, choosing the right one can be overwhelming. One popular choice is the ear thermometer. But is it both accurate and safe? Let's explore further.

Types of Thermometers

According to the Mayo Clinic, thermometers used for measuring body temperature generally fall into two categories:

• Contact thermometers: These thermometers require direct contact with the forehead, mouth, armpit, or rectum and provide a reading within seconds to a minute.
• Non-contact thermometers: These devices utilize infrared technology to detect body temperature by measuring heat emitted from the arteries in the forehead or ear. One of the most commonly used non-contact thermometers is the tympanic thermometer, also known as an ear thermometer.

Understanding Ear Thermometers

Ear thermometers measure body temperature by detecting infrared heat from the eardrum (tympanic membrane). According to the National Health Service (NHS), as cited by Medical News Today, ear thermometers can provide highly accurate readings when used correctly.

Although ear thermometers are considered more reliable than some other non-contact thermometers, their accuracy may be affected by several factors, such as:

• Incorrect positioning of the thermometer.
• Size and depth of the ear canal.
• Earwax buildup.
• Moisture inside the ear.

How to Use an Ear Thermometer

• Gently pull the earlobe upward or backward.
• Carefully insert the thermometer tip into the ear canal, aiming it toward the eardrum, not the ear wall.
• Turn on the thermometer and wait for the reading to complete.
• Remove the thermometer once the measurement is displayed.

Understanding Temperature Readings

Body temperature can fluctuate based on external factors, including the time of day. Generally, body temperature is lower in the morning and slightly higher in the evening.

The average normal body temperature for adults typically ranges between 36.5°C to 37.5°C. A person is considered to have a fever when their body temperature exceeds 38°C.

Who Can Use an Ear Thermometer?

Ear thermometers are recommended for children over six months old. However, they may not be suitable for individuals with the following conditions:

• Using ear drops as part of medical treatment.
• Excessive earwax buildup that could interfere with readings.
• Ear infections or other medical conditions affecting the ear.
• Discharge of fluid or blood from the ear.
• Persistent ear pain.
• Recent ear surgery.

If you are looking for a reliable and safe thermometer for the whole family, an ear thermometer is a great option. These thermometers are available at pharmacies and medical supply stores.
