How Do They Work?
In recent days, thermometers have become quite easy to read, compared to the past where people had to rely on a mercury thermometer that required someone with a little bit of experience and know-how about them.
The new types of thermometers will provide readings on an easy to read digital display screen that you can comfortably understand in your home.
Now, depending on the settings, you can either find these readings in Fahrenheit and Celsius. To obtain the correct measurement, ensure to turn on the thermometer, and place it on the recommended body part either the forehead, the rectal, or the underarm or even orally.Once it is in place, do not keep moving about. Keep it on the body part, till it makes an alert sound or till an appropriate temperature is recorded on the screen.
It is, however, important to ensure that the thermometer is always clean before using it. Read the manufacturer’s instructions carefully to ensure you are correctly using the thermometer, so it can give you accurate results.
It is also recommended that you check the temperature 2-3 times before deciding on the correct reading so you can be 100% sure.
Most digital thermometers will use electronic heat sensors or infrared light to measure and record the body temperature from the mouth, forehead, rectum or ear.
The most recommended measurement is through the mouth or the rectum as these tend to give the most accurate readings.
Again, depending on the device you have, digital thermometers normally give these results in just a few minutes. But if you have just had a meal and you want to be sure of the reading, ensure to wait 15 minutes because this can impact the reading on the thermometer.
If you are going to take the measurement of your child via the rectum, it is highly recommended that you follow the manufacturer’s instructions to the letter in order to avoid causing too much discomfort and to also make the thermometer accurate in its reading.
The Most Recommended Ways of Measuring Temperature With a Thermometer
Behind the ear method:
As the name suggests, this is a measurement of the temperature by placing the thermometer behind the ear. Please note that if the thermometer says behind the ear, it should strictly be done behind the ear and not inside the ear.
Thermometers that use this method are supposed to be placed against the skin on the ear for optimal comfort and minimal irritation.
The only downside to this method is that it is not always consistent, because taking measurements outside the body can be affected by various factors such as the environment, sweat, clothing and heat changes.
You must also wait for the ear to be in the normal temperature and comfortable before taking the temperature which may take a few minutes to achieve.
Temporal artery or forehead method:
The thermometers that use this method usually make use of infrared lights to relay the readings from the thermometer. In fact, this is one of the best ways to take the temperature readings as the thermometer rarely ever gets into contact with the body.
This method is designed for optimal comfort and its perfect for children that are uncomfortable or unable to use the oral or rectal method.
Since this is an external temperature measurement, it may be affected by external factors such as sweat, heat, temperature, and even clothing. These may alter the temperature readings, so, be sure to keep the forehead clear, and if it had been covered, give it time to breathe before using the thermometer.
This is one of the most popular methods in the market today. It is commonly used by healthcare professionals and even parents and it is actually considered one of the best and most accurate methods of checking the temperature.
The thermometers that use this method will take the temperature using metal or heat sensing by placing and holding the thermometer below the tongue. The metal then measures the body temperature from moment to moment and looks for the best and most stable signal.However, in order for it to correctly and accurately measure the temperature, the user must be able to hold it under their tongue and keep the mouth closed for an accurate reading to be obtained, which is not always possible and easy with small children.
If you have been eating and drinking, wait 15 minutes before taking the temperature using this method.
As mentioned earlier, this is not an ideal method for infants, toddlers, and newborns as they cannot hold still, plus, it may actually become a danger to their health if there is too much movement and crying as you are trying to take their temperature. Use it on adults and teenagers.
This is the best, safest and most accurate method of measuring temperatures, especially for very young children. As the name suggests, this is inserted anally in order to take the body temperature.
The thermometers that use this method normally have a blunt, short and rounded tip that can be inserted in the rectum carefully without causing any discomfort or injury to the soft tissue in the rectum and also minimal pain.
Because of its accuracy and safety, this is considered the best method to use on newborns, young children, and toddlers.
Almost everyone has used this method at one point or another. Checking your temperature by placing the thermometer under your arm is one of the most commonly used methods in the world.
What you do is, place the thermometer under your arm, then close it till it gives an accurate measurement of your temperature.
Though popular, it is not the most accurate and recommended method to use and has actually become less common. This is because it is believed to be less accurate compared to the other methods listed above. The reason for this is that the underarm is affected by many things such as body movement, sweating, varying temperature zones, and hair.
Featuers of Thermometers
Nowadays, digital thermometers have most definitely replaced the old mercury thermometers. This is because a digital thermometer allows you to take measurements electronically and provides feedback through a digital display. This is definitely much better than trying to read the mercury level of the mercury thermometer.
Now to make the medical digital thermometer perfect for you, look for one that offers the following features;
Backlight display screen – In order for you to read the numbers accurately, look for a thermometer that has a large display screen and one that has a backlight so you can be able to read the temperature even at night.
Alert signal – This is perfect because it is a buzzer or a beeping sound that goes off when the allotted time has lapsed. It lets the user know that they can now read the thermometer as the temperature of the patient has been recorded. This is perfect especially for the underarm method since you do not have to sit there the whole time waiting for the reading or guessing when the temperature has been arrived at. You simply insert it on the user and leave it till you hear a beep.
Some thermometers come with built-in memories that can allow you to check the last several temperatures taken. This is perfect for when you need to track the progress of your patient and it gives a history of how they are doing.
Color changes for temperature warnings:
Some digital thermometers actually change color on the display whenever the temperature is over a certain number or when it is very high. In most cases, the backlight part of the thermometer will turn red, and let you know that things are not good, so, you may take the necessary steps.
The faster the thermometer is at taking readings, the better. This is because you will be able to quickly identify the temperature of the sick person and take appropriate measures in ensuring their well-being. Fever is a leading cause of death, and if you are able to identify that someone has a high fever quickly, the faster it will be for you to take them to the hospital.
Some thermometers, however, take too long to record the temperature and this is not ideal. Choose one that is very fast. It could save a life.
Long battery life:
They do operate on battery. Some use button cell batteries, while others use standard AAA or AA batteries. Whichever one you use, battery life is important, and some thermometers actually do last a very long time.
It is however still a good idea to keep a separate pair of batteries just in case the thermometer runs out. This will save you time when you need to buy new batteries and there is an emergency situation. It is always better to be safe than sorry.
Though a thermometer that comes with many additional features can be tempting to choose, having one that has a high level of accuracy is actually much better and more reliable. This should be the most important point to consider when buying a thermometer.
While there are many thermometers in the market, those that take the temperature orally and through the rectum tend to be the most accurate and most trusted because their technology to measure the temperature consistently after multiple readings.
In order to get the most accurate readings on a thermometer always wait a little longer to take the reading, because the thermometer will have identified the most accurate temperature on the user.
Consider the safety of the user before buying a thermometer. This is because different thermometers use different methods to check the temperature and you may end up with a difficult situation in your hands if you have a very difficult patient.
For infants and newborn babies, an ear or rectum or forehead thermometer would be ideal, while for adults and people who can actually be able to sit still, a tongue or underarm thermometer will be just fine.
Fahrenheit or Celsius:
Thermometers measure the temperature using these 2 units. You must consider the one that you like most and the one that is easiest for you to understand before buying a thermometer because you do not need a situation where you keep doing the math conversions when you urgently need to know how hot your child is.
Types of Thermometers
There are very many types of medical thermometers that can be used to measure body temperature.
Depending on the one you choose, thermometers measure temperature from different parts of the body, and each method of measurement is specific to that thermometer, so be sure to check the manufacturer’s instructions before using it in your own way.
Digital forehead: As the name suggests, this is a thermometer that uses the forehead method to measure the temperature.
Digital ear thermometer: This one takes temperature measurements by placing the thermometer behind the ear, or inside the ear.
Digital sticks: These measure the temperature by placing them under the arm.
Pacifier thermometers: These are perfect for infants and are considered a comfortable alternative to most other types of thermometers. They normally resemble a baby’s pacifier, and in most cases they give accurate results but they are not recommended as their accuracy is varies depending on whether the baby just ate, or if it is moved around a lot, and also the baby may never be able to sit still in order for it to give a reading.

Frequently Asked Questions
1. After taking the temperature with the thermometer, why does the temperature keep rising?
This is common to most thermometers in the market. The reason is that, after the thermometer has completed checking the temperature, it is still sensitive to temperature increases. Before using the thermometer, follow the following steps so you do not have inaccurate figures.
Keep the thermometer and the patient in the same room for at least 20 minutes prior to taking their temperature. Also, avoid using the thermometer in a cold environment.
Do not measure on parts of the body that have cooled or have been heated by drinks or food.
If you can, use oral or rectal thermometers since they give the most accurate results.
If you have an underarm thermometer, keep it still under the arm and very close to the body until the thermometer beeps that it has measured the temperature.
2. How accurate are thermometers?
Thermometers are generally very accurate. In most cases, the degree of accuracy is normally between ±0.2ºF or ±0.1ºC. This means that you can generally be able to rely on them all the time.
You should however note that taking the temperature of your child or sick patient doesn’t necessary allow you to continue and give a treatment cause, because thermometers are meant to merely give an indication that something is wrong.
If you have a patient with a high temperature reading, ensure to seek medical attention for further evaluation and diagnosis, because it is always a sign that something is wrong. The doctor will them be able to come up with a prognosis on how to treat the infection or underlying medical condition.
3. Must I put the thermometer under my arm to check the temperature?
Now, as much as this is the most common method of checking body temperature using the thermometer, you should know that it is infact one of the most less accurate method as well.
When you measure the temperature using the underarm, it is normally affected by many things such as body movement, sweating, varying temperature zones and hair. As a result, this is not always the most accurate reading, and you may actually need to take the temperature a few more times and get the average reading in order to know how high or low the patient’s temperature is.
4. How long does it take to get the reading from a thermometer?
Each thermometer has its own speed level. Some are fast, while others are slow. If you want to do a quick check, ensure to buy a very fast thermometer that will ensure you get the most accurate reading in the shortest time possible.
However, a thermometer should never take more than 5 minutes to give you a reading. If it does that, it may be faulty and you must never rely on the readings given by such a device.
A quick point to note here however is that if your patient has had a drink or had some food just before taking their temperature, it is always advisable to wait a few minutes before using the thermometer as this may affect an accurate reading.
5. Does the thermometer require refrigeration?
In the past, and when people used to have the mercury thermometers, there was this rule that they must always be kept in the refrigerator. That is however not the case anymore and you do not have to keep your thermometer in the refrigerator as it is designed to be stored at room temperature.
6. Must I always use a cotton pad when using the thermometer? How often should I clean it?
Using a cotton pad before checking the temperature with a thermometer is very common, especially in hospitals where the same thermometer is used by many people in the house.
Thermometers such as those used in the ear, in the rectum or the mouth must always be used together with the cotton pad in order to clean the area, and even disinfect it. You must always clean the thermometer before using it on every new person.
Keeping it clean will ensure that it is always hygienic and it will not transfer germs from one person to another.
It is however important to always follow the manufacturer’s advice when using the thermometer and when it comes to hygienic practices, because there may be some specific instructions concerning its clean up that you may be unaware of.
7. How do I store my thermometer?
