Fever is one of the most common symptoms of various diseases and illnesses. From common colds and flu to serious infections like pneumonia and COVID-19, is a sign that something is wrong with the body. That’s why it’s important to know how to measure fever accurately so you can take the necessary steps to keep yourself and your loved ones healthy.

There are several ways to measure body temperature, but some methods are more accurate than others. Let’s take a look at some of the most popular methods and their pros and cons.

Oral Temperature

Oral temperature is a common method of measuring fever. Simply place a thermometer under your tongue and wait for the reading. This method is easy, convenient, and safe for most people. However, it may not be suitable for young children or elderly people who have difficulty holding the thermometer under their tongue for a long time. Additionally, drinking hot or cold beverages, smoking, and breathing through the mouth can affect the accuracy of the reading.

Axillary (Armpit) Temperature

Axillary temperature is another method of measuring fever that’s easy to do. Place a thermometer in the armpit, making sure it touches the skin, and hold the arm close to the chest for a few minutes. The reading may take longer to get than oral temperature, but this method is safe for all ages. However, it may not be as accurate as other methods, especially if the thermometer is not placed correctly or the armpit is not dry.

Rectal Temperature

Rectal temperature is the most accurate method of measuring fever, but it may not be suitable for everyone. Use a thermometer with a rounded tip and enough lubrication, and place it about an inch into the rectum. This method is usually reserved for infants, young children, and people who are severely ill or unable to use other methods. It can be uncomfortable and invasive, so it’s important to follow the instructions carefully and use caution.

Ear Temperature

Ear temperature is a quick and easy method of measuring fever that’s suitable for all ages. Use an infrared thermometer to measure the heat radiation from the ear canal, and compare it to a reference chart. This method is non-invasive and doesn’t require waiting time, but it may not be as accurate as rectal temperature, especially if the ear canal is dirty or blocked.

Temporal Artery Temperature

Temporal artery temperature is a newer method of measuring fever that’s gaining popularity. Use an infrared thermometer to scan the forehead or temple area, and compare it to a reference chart. This method is non-invasive, quick, and suitable for all ages. However, it may not be as accurate as rectal temperature, especially if the forehead is sweating or the thermometer is not placed correctly.

No matter which method you choose, it’s important to use a good-quality thermometer and follow the instructions carefully. Keep in mind that normal body temperature may vary depending on age, gender, time of day, and physical activity, so it’s important to know your baseline temperature and monitor any changes. If you or someone you know has a fever that lasts more than a few days, or is accompanied by other symptoms like cough, sore throat, body aches, or difficulty breathing, seek medical attention right away. Fever can be a sign of a serious infection or illness that needs prompt treatment. Stay healthy and stay safe!
