When to Use a Small Thermometer
Feeling a little under the weather lately? One of the first things you may reach for is a thermometer to check if you have a fever. But how do you know when it’s really time to grab that handy little device? Small digital thermometers make temperature taking a cinch – when used at the right times.
Monitoring your body temperature can provide vital health insights. But taking your temperature too often can lead to unnecessary anxiety. So when should you whip out a small thermometer to take your temp?
When You Feel Feverish
Feeling feverish is one of the most common reasons to take your temperature. Symptoms like chills, body aches, headache, and fatigue often accompany a fever. If you have these symptoms, take your temperature to see if it is elevated. A reading over 100°F (37.8°C) confirms a fever.
Knowing you have a fever can help guide treatment. Doctors may recommend fever reducers, increased fluids, and rest. Fevers may also indicate when medical evaluation is needed, especially with high fevers over 103°F (39.4°C).
When You’re Ill
Certain illnesses like flu, COVID-19, tonsillitis, pneumonia, ear infections, and UTIs can cause fevers. Taking your temperature when sick helps monitor the course of the illness and effectiveness of treatment.
For example, if you start an antibiotic for an infection and your fever comes down, it suggests the medication is working. Check with your doctor on what temperature readings warrant a call to the office when ill.
Infant or Child is Fussy
Infants and small children can’t verbalize when they feel ill. Fussiness, reduced appetite, and sleepiness may indicate sickness. Taking a baby’s temperature when they seem uncomfortable can detect an unseen fever.
New parents should have an easy-to-use small thermometer on hand to frequently check baby’s temp when unwell. fevers in infants warrant prompt medical attention.
After Vaccinations
It’s common for babies to develop a mild fever after getting vaccinations. Taking their temperature a few times in the hours after shots helps identify this expected side effect.
Monitoring temperatures can also assure parents that the fever resolves within a day or so. Call the doctor if fever lasts over 24 hours after vaccinations.
When Tracking Ovulation
Some women notice a slight temperature increase of around half a degree when ovulating. Taking your basal body temperature with a small thermometer each morning can help identify when you’re ovulating.
This can aid couples who are trying to conceive in timing intercourse optimally. Look for this basal temperature spike on days 10-15 of your menstrual cycle.
If You Feel Hot or Chilled
Feeling unusually hot or chilled can also prompt a temperature check. Chills may indicate the onset of an illness or fever.
On the other hand, feeling hot and flushed may reflect menopausal hot flashes, overheating from exercise, or even anxiety. A temperature reading can help discern the cause.
When Monitoring a Medical Condition
Those with chronic medical conditions may need to routinely monitor temperatures. Conditions like diabetes, recurrent UTIs, inflammatory bowel disease, and immune disorders can involve temperature instability.
Checking your temp when you feel unwell provides data for your doctor to assess disease control. But also take it when feeling well to establish your normal baseline.
Before Bed
Taking your temperature before bedtime can serve as a baseline. You can then compare it to overnight or morning temperatures to see if it becomes elevated, indicating illness.
Having this evening baseline temperature improves interpretation of later readings. Mark down each reading to identify temperature trends.
When Caring for an Elderly Person
Frail elderly individuals may not notice or communicate symptoms of illness. Regular temperature screening by caregivers can identify medical issues like infections needing attention.
Note any temperature over 100°F (37.8°C) or 2+ degrees over the person’s baseline. Report these to a doctor to determine if treatment is appropriate.
During or After Surgery
Doctors routinely monitor patient temperatures after surgical procedures to watch for post-operative infection. Temperature spikes after surgery usually require further evaluation and treatment.
At-home monitoring with a small thermometer after discharge provides data to inform follow-up care. Avoid confusion by noting the time of day with each reading.
When You Just Feel “Off”
Sometimes you may just feel generally crummy without specific fever symptoms. Taking your temperature when you feel “off” can reveal an elevated reading warranting medical care.
Trust your instincts and reach for the thermometer when your body gives vague indications that something may be amiss. Better safe than sorry if a fever is brewing.
During illness or any condition causing temperature instability, take readings multiple times a day to establish trends. Keep a temperature log to provide your physician complete information.
Having a compact, easy-to-use small digital thermometer makes frequent temperature checks simple and fast. Keep one handy in your medicine cabinet, so it’s available whenever feeling under the weather strikes. Monitoring your temperature provides valuable health insights to discuss with your doctor.
How to Properly Take a Temperature
Taking someone’s temperature is a simple and common way to check for signs of illness or infection. However, there are some important tips to follow to ensure you get an accurate reading. With a few basic steps, you can become a pro at taking temperatures.
Choosing the Right Thermometer
The first step is selecting the proper thermometer. Here are the most common options:
- Digital thermometers – These electronic thermometers provide a quick digital readout. They are inexpensive, easy to use, and accurate. Just be sure to clean the tip before and after each use.
- Ear or forehead thermometers – These use an infrared scanner to take the temperature. They are very fast but tend to be less reliable. Only use them if you’ve verified their accuracy.
- Rectal thermometers – Considered the most accurate method, but invasive. Only use for infants or when maximum accuracy is critical.
- Oral thermometers – The traditional choice, but can be less sanitary. Be sure to clean thoroughly and avoid biting down.
For routine temperature taking, a digital thermometer is recommended. They provide the best combination of speed, accuracy, and convenience.
Preparing the Person
Proper set up will help ensure you get an accurate reading:
- Wait at least 15-20 minutes after eating, drinking, exercise, or bathing since this can impact temperature.
- Have them sit comfortably in a chair or laying down. Movement right before taking temperature can alter results.
- Remain calm and relaxed. Stress and anxiety can temporarily increase temperature.
- Take temperature in a draft-free room. Air currents from fans, open windows, or air conditioning can lead to erroneous readings.
Taking a Proper Oral Temperature
When using an oral thermometer, follow these steps:
- Make sure the thermometer is clean by washing it with soap and water or disinfecting with alcohol.
- Turn on the thermometer and make sure it is reset to its lowest temperature.
- Place the thermometer tip under the tongue toward the back of the mouth. Ask the person to close their lips tightly around it.
- Have them breathe through their nose – no talking!
- Hold the thermometer in place for the required amount of time – usually 30-60 seconds until it beeps or displays the reading.
- Read and record the temperature, then clean the thermometer.
Key tips: Don’t let them bite down and don’t take temperature right after drinking a hot or cold liquid.
Taking a Temperature Rectally
For babies or when maximum accuracy is needed, a rectal temperature is best. To take:
- Lubricate the tip with a water-soluble jelly for easier insertion.
- Lay the baby belly-down across your lap or have an older child kneel and bend forward.
- Gently insert the thermometer about 1 inch into the anus.
- Hold it still for the required time until it signals – usually 30-60 seconds.
- Remove thermometer and clean thoroughly with soap and water.
Rectal temperatures run about 1 degree higher than oral readings. Only use rectal method for children under 5 years old.
Reading and Resetting
Once done taking the temperature:
- Read the number and write it down along with the time and date.
- Reset the thermometer back to its lowest temperature setting.
- Disinfect the thermometer probe before storing.
Normal temperature is generally considered 98.6°F (37°C) but can range from 97.5–99.5°F (36.4-37.5°C). Keep track of temperatures over time and call a doctor if someone has a temperature over 100.4°F (38°C) or if elevated temperatures last for more than 2-3 days.
What to Avoid
Some common thermometer mistakes include:
- Not cleaning the probe between uses
- Not waiting long enough for an accurate reading
- Letting the probe touch tongue, cheek, teeth or gums
- Not tightly closing lips around oral thermometer
- Not properly inserting rectal thermometer
- Not noting the time and date with each reading
With a quality thermometer and proper technique, temperature taking doesn’t need to be complicated. Just remember the preparation, proper placement, and avoidance of mixing foods or drinks during the process. With practice, taking accurate temperatures will become second nature.
Normal Temperature Ranges
Understanding normal body temperature ranges is important for monitoring health. While 98.6°F (37°C) is the benchmark, a person’s temperature can vary throughout the day and still be considered normal.
Oral Temperature Range
For oral temperature, which is taken by mouth using a thermometer, the standard normal is 98.6°F or 37°C. However, this is more of an average than a hard rule. The typical normal oral temperature range is:
- 97.8–99.1°F (36.5–37.3°C) for adults and children over age 5
- 97.9–100.4°F (36.6–38°C) for children aged 1-5 years
- 97.5–100°F (36.4-37.8°C) for babies under 1 year
Temperatures on the lower end are normal and do not necessarily indicate a problem. Oral readings up to 100.4°F (38°C) may still be considered normal, especially later in the day. Higher temperatures in the evening are common.
Rectal Temperature Range
Rectal temperatures, taken with a thermometer inserted shallowly into the anus, run about 1 degree higher than oral readings. Normal rectal temperature ranges are:
- 99–100.6°F (37.2–38.1°C) for adults and children over age 5
- 99–101°F (37.2–38.3°C) for children aged 1-5 years
- 99–100.9°F (37.2-38.3°C) for babies under 1 year
Rectal temperature is considered the most accurate method but is used primarily for infants or when maximum precision is needed.
Ear Temperature Normal Range
Ear or tympanic temperature is taken electronically by scanning the eardrum with an infrared thermometer. Normal ranges are:
- 97.5–99.5°F (36.4–37.5°C) for infants, children and adults
Ear temperatures tend to be close to rectal readings. However, ear thermometers are less reliable and accurate than other methods.
Forehead Temperature Normal Range
Forehead or temporal artery thermometers use an infrared scanner across the forehead. Normal is:
- 97.5–99.5°F (36.4–37.5°C)
Like ear temperature, forehead readings have more variability than oral or rectal methods.
Factors Affecting Normal Temperature
Many factors can alter body temperature throughout the day. Normal fluctuations can occur due to:
- Time of day – Temperatures tend to peak in the evenings
- Age – Infants and elder adults run lower temperatures
- Activity level – Exercise and metabolism increase heat
- External conditions – Hot or cold environments affect body temperature
- Hormones – Ovulation and menstruation cause variances
- Medications – Some drugs influence thermoregulation
What matters most is the pattern and any variations from an individual’s normal baseline temperature range. Sudden high spikes, low temperatures, or fluctuations can signify an underlying problem.
When a Temperature Is Considered a Fever
In general, a fever is technically defined as a body temperature over 100.4°F (38°C). However, lower temperatures can still be considered a fever if much higher than normal for a given individual. Other fever guidelines include:
- Oral temperature over 100.4°F (38°C)
- Rectal or ear temperature over 101°F (38.3°C)
- Forehead temperature over 100.4°F (38°C)
Fevers are commonly a key sign of infection or illness. If a fever lasts more than 2-3 days, be sure to contact a doctor. Pay attention to any sudden spikes in temperature as well.
Tracking Changes Over Time
To best assess normal body temperature, measure and track it regularly. Note the time of day, method used, and any factors that may have influenced the reading. Watch for variations outside of normal daily fluctuations or your personal baseline ranges.
Understand the typical normal temperature ranges based on site and method used. This provides context for monitoring any given individual. Consistency in timing and technique is key. Contact a physician for guidance on any concerning readings or prolonged abnormalities.
Signs of a Fever
A fever indicates an elevated body temperature, usually due to an underlying illness or infection. But how do you know if someone has a fever without taking their temperature? There are some key signs to watch out for.
Flushed Skin
One of the most common physical signs of a fever is flushed or reddened skin on the face, neck, or body. This occurs as blood vessels dilate to allow more heat release from the skin’s surface. The higher the fever, the more flushed the skin appears.
In light-skinned individuals, the flushed areas may appear pink or red. In darker complexions, the skin may look more flushed than usual. Heat rash can also develop, causing red bumps or patches on the skin that feels hot to the touch.
Sweating
Fever often triggers sweating as the body tries to cool itself down. Any sweating occurring without exertion or high temperatures may be indicative of an elevated internal body temperature.
Sweating is especially common with fever at night, which can cause someone to wake up drenched in sweat. The sweating may be most pronounced on the chest, face, neck, back, and palms of the hands and feet.
Chills, Shivering & Body Aches
Someone with a higher than normal temperature may feel chilled, shiver, and have flu-like body aches. The chills are caused by rapid muscle contraction and relaxation as the body tries to generate more heat through involuntary shivering.
Alternating chills with excessive sweating is particularly telling. The muscle aches seem flu-like, often occurring in the back, arms, and legs. Headaches and general malaise are also common.
Lack of Appetite
Low appetite and nausea frequently accompany a fever. The body is diverting energy toward mounting an immune response, decreasing digestive function in the process. Food may be unappealing or even make someone feel sick to their stomach.
In babies and younger children, refusing to eat or drink as normal is often one of the first fever symptoms noticed. Dehydration is a potential complication.
Irritability & Lethargy
Fever, chills, body aches, and nausea make a person feel unwell, which leads to mood changes like irritability, crying, and lack of interest in normal activities. The fever is sapping the body’s energy.
Lethargy, drowsiness, and lack of energy are common fever symptoms. Someone may sleep or rest more than usual. With an elevated temperature, any movement or activity takes more effort and feels exhausting.
Confusion & Disorientation
A very high fever can cause confusion, delirium, hallucinations, and trouble thinking clearly. This is a medical emergency, as temperature over 104° F (40° C) can lead to seizures, brain damage, or death.
In children, look for any strange behavior that seems out of character. Adults may act confused about their location or identity, be unable to follow simple instructions, or have garbled speech.
Measuring Temperature
The most definitive way to identify a fever is to take someone’s temperature. Oral thermometers are recommended for routine temperature taking. Ear, forehead and temporal artery thermometers are faster but less reliable alternatives.
Any temperature over 100.4° F (38° C) indicates a significant fever, especially if over 102° F (39° C). However, even a lower grade temperature can be considered fever if elevated for that particular person.
Duration of Fever Symptoms
Pay attention to how long fever symptoms persist. A common cold may cause a low-grade fever for a day or two. The flu brings on a higher fever lasting around 3-4 days.
Any fever lasting longer than a week requires medical attention. The same applies to infants under 3 months with a rectal temperature over 100.4° F (38° C). Be alert for any other worrying symptoms accompanying the fever.
Call the Doctor If…
Contact your doctor if:
- Fever over 102° F (39° C) in adults, over 101° F (38.3° C) in children
- Fever lasts longer than 3 days in adults, 2 days in children
- Recurrent fevers keep returning
- Fever accompanied by severe headache, neck stiffness, mental changes, difficulty breathing, or rash.
Trust your instincts. Even low-grade sustained fever or any unusual fever symptoms warrant a doctor visit. Fever often provides an important early warning of underlying illness.
How Accurate Are Small Thermometers?
Small digital thermometers have become a popular choice for temperature taking at home due to their affordability, ease of use, and fast results. But how reliable are these mini thermometers? Here’s an overview of their accuracy.
Overall Accuracy
In general, modern digital stick thermometers provide accurate temperature measurements falling within +/- 0.1-0.2 degrees Fahrenheit of a reading taken simultaneously using a standard oral or rectal mercury thermometer.
Clinical studies evaluating various models of digital thermometers compared to glass mercury versions show that the small digital options reliably produce results well within the acceptable range for accuracy.
Advantages Over Mercury
The precision of digital sticks actually exceeds old-fashioned mercury thermometers in several ways:
- Quick precise readout rather than estimating where the mercury line falls.
- No risk of broken glass and mercury exposure.
- Measures in 10 seconds versus 3+ minutes for mercury.
- Can take many back-to-back readings quickly.
- Stores previous temperature readings.
- Some models beep when finished.
For these reasons, trusted health organizations including the Mayo Clinic recommend switching to digital thermometers over mercury ones.
Oral vs. Rectal Readings
One accuracy consideration is that digital stick thermometers provide more precise oral temperature readings than rectal.
Rectal thermometers are shaped specifically to insert shallowly into the anus for maximum accuracy. Oral digital models are not ideal for rectal use. However, for oral temperature taking, digital stick thermometers perform very well.
Proper Technique
To ensure optimum accuracy with a digital oral thermometer:
- Wait 15-20 minutes after eating, drinking, or exercise.
- Place carefully under the tongue toward the back of mouth.
- Ensure lips seal tightly around thermometer probe.
- Avoid biting down or touching teeth/tongue.
- Hold in place until it beeps – usually 10 seconds.
Proper measurement technique is key for any thermometer. Digital options provide more room for user error than mercury since they measure so rapidly.
Regular Calibration
Like any thermometer, digital sticks lose calibration over time with heavy use. Replace your thermometer annually or any time results seem inaccurate compared to how you normally feel.
Some models let you manually recalibrate by pressing a button. Compare against a known accurate thermometer like recently calibrated mercury one from your doctor’s office.
Look for Quality Models
Here are signs of a high-quality digital thermometer for optimal accuracy:
- Meets ISO accuracy standards
- Has been clinically tested for precision
- Recommended by medical experts and organizations
- Trusted brand with good reputation
- Good owner reviews and feedback
- Long battery life and warranty from manufacturer
There are many inferior products out there, so choose carefully. Spending a little more upfront ensures you get precise consistent results.
Know the Limitations
While generally reliable for typical temperature taking, oral digital thermometers may be less accurate in certain circumstances:
- Very high or very low body temperatures at extremes.
- Rectal versus oral route usage.
- Old thermometers in need of recalibration.
- Poor measurement technique.
- Comparing single time measurement versus tracking temperature continuously.
- Severe hypothermia or hyperthermia life-threatening states.
For serious illness or emergencies, doctors have more sophisticated thermometer options. But for daily use, a quality digital stick thermometer provides accurate results you can rely on.
Tips for Getting an Accurate Reading
Taking an accurate body temperature is vital for assessing health. However, many factors can impact the reading. Here are tips to help get a precise temperature measurement.
Choose the Right Thermometer
Opt for an oral digital thermometer. These offer the best balance of affordability, ease of use, speed, and accuracy for home temperature taking. Make sure to replace it annually.
Use Proper Placement
For oral readings, place the thermometer tip under the tongue toward the back of the mouth. Close lips tightly around it. Avoid biting down or letting it touch the tongue, teeth or inner cheeks which can alter the results.
Take the Time
Leave the thermometer in place until it signals completion (usually 10 seconds for digital). Removing early can lower the reading. For rectal use in infants, insert only 1 cm and hold for up to 60 seconds for an accurate core body temperature.
Get in the Habit
Take temperature at the same time daily as body temperature varies throughout the day. Consistency gives the best sense of an individual’s normal.
Note the Conditions
Record details like time taken, temperature method, recent medicines, activity level, and environment. These details provide context affecting temperature.
Avoid Eating and Drinking Before
Wait at least 15-20 minutes after eating or having cold/hot beverages as food and drink impact oral temperature. Also avoid taking right after exercise or a bath which can briefly alter readings.
Mean Multiple Readings
For best accuracy, take 2-3 back-to-back readings and use the average. Repeated measurements minimize normal fluctuations.
Try Different Methods
If concerned about accuracy, compare your digital oral stick to a rectal or ear reading. Rectal thermometers are considered the gold standard, especially for infants.
Ensure Proper Conditions
Take temperature in a draft-free room without air currents from fans, open windows, or air conditioning which can distort results. Stay relaxed as stress affects temperature.
Disinfect Between Uses
Always clean the thermometer tip with soap and water or rubbing alcohol between readings to prevent transmitting bacteria.
Know Your Baseline
Track your regular temperature readings over time to determine personal average, fluctuations and any abnormalities for you individually.
Replace Batteries
Make sure your digital thermometer has fresh batteries. Weak batteries lead to inaccurate low readings. Most last approximately 2000 readings before needing replacement.
Recalibrate Annually
Check calibration periodically against a known accurate thermometer. Recalibrate if readings are off. Replace oral digital models annually for best performance.
Following these tips helps minimize normal variability in temperature taking. Be systematic in technique, conditions, timing, and recording details to get the most accurate reading possible.
Checking a Baby or Child’s Temperature
It’s important to know how to properly take a baby or child’s temperature. Young children can’t communicate how they feel, so checking for fever is key. Here are tips for getting an accurate reading.
Choose the Right Thermometer
For babies under 3 months, a rectal thermometer is recommended. Older babies and toddlers need a digital thermometer designed specifically for oral/rectal/armpit use with a flexible tip.
Look for digital sticks offering accurate readings in only 10 seconds to keep squirmy kids still. An appealing color helps too!
Rectal Readings for Under 3 Months
Rectal temperature is the gold standard for accuracy in infants. To take:
- Lay baby tummy-down across lap or have an older child kneel and bend forward.
- Gently insert the tip only 1 cm into the anus.
- Hold for up to 60 seconds until thermometer beeps.
- Remove and clean thoroughly with soap and water.
Rectal runs about 1 degree higher than oral. 100.4°F (38°C) rectal is considered fever in babies under 3 months.
Oral Readings for Older Babies & Toddlers
For ages 4 months to 3 years, carefully take an oral temperature by:
- Insert tip under tongue near back of mouth.
- Have child close lips around thermometer.
- Gently hold it there until the 10 second beep.
- Distract child by stroking their cheek or Singing.
Oral readings are lower than rectal. For ages 1-5 years, over 100°F (37.8°C) oral indicates fever.
Armpit Readings
If oral temperature taking is challenging, place the flexible tip in baby’s armpit instead. Hold arm down for an accurate reading.
Axillary temperatures run about 1 degree lower than oral. A fever threshold here would be 99°F (37.2°C).
Ear Thermometers
Infrared ear thermometers can provide quick readings. However, accuracy depends on proper technique and they tend to be less reliable in young children. Use as a secondary temperature method only.
Forehead Strips
Disposable thermometer strips or stickers that adhere to the forehead are convenient but not recommended. They are highly variable and inaccurate for assessing fever in babies and children.
Timing Matters
Take temperature when symptoms seem worst, usually late afternoon or evening as fevers tend to rise throughout the day. Record time taken with the reading.
Be Consistent
Always take temperature in the same location each time (oral, rectal, armpit, ear) for consistency. Compare apples to apples when looking for fever.
Learn Normal Range
Know your child’s usual temperature range when well. Any reading above their norm could indicate fever, even below the standard fever thresholds.
Note Other Symptoms
Fever often coincides with flushed skin, sweating, chills, reduced appetite, and irritability in children. Look for associated symptoms.
When to Call the Doctor
Consult your pediatrician if baby under 3 months has a rectal temperature over 100.4°F (38°C) or for any fever concerns in a young infant. For older babies and children, call for fevers over 102°F (39°C) or any fever lasting over 2 days without explanation.
Knowing the proper thermometer type and method for checking your baby or child’s temperature helps ensure you get an accurate reading to assess for fever or illness.
Taking Your Temperature Orally
One of the most common ways to check your body temperature is by taking it orally using a thermometer. Here are tips for properly taking an oral temperature reading at home.
Choose the Right Thermometer
Digital thermometers are recommended over mercury for home use. Seek out a digital stick thermometer that’s affordable, easy to use, provides fast (10 second) readings, and specifically designed for oral use.
Prepare Properly
Avoid eating, drinking, exercising, or bathing for 15-20 minutes beforehand as this affects oral temperature. Also pick a draft-free room without air currents from fans, AC, or open windows.
Clean the Thermometer
Always clean the thermometer tip before and after use with soap and water or rubbing alcohol to prevent spreading germs.
Turn Thermometer On
Digital thermometers need to be turned on first and reset to the default lowest reading (usually around 94°F or 34°C). Make sure fresh batteries are installed.
Place Under Tongue
Gently place the thermometer tip as far back under your tongue as comfortable, near but not touching the bottom of your mouth.
Close Lips Tightly
Completely close lips to seal around the thermometer. Don’t bite down on it. Keep lips sealed until it beeps.
Hold Steady
Hold the thermometer in place under your tongue without moving, talking, or disturbing it until the reading is complete, about 10-20 seconds. Breath through your nose.
Note the Reading
When it beeps, remove thermometer and note the temperature reading along with time and date. Normal oral temperature is 97.6-99.6°F (36.4-37.6°C).
Take 2-3 Times
For best accuracy, take your temperature 2-3 times in a row at the same session and use the average. This minimizes normal fluctuations.
Try Other Methods
If concerned about oral reading accuracy, also take a rectal or ear temperature for comparison. Rectal is considered the most precise.
Clean After Use
Always sanitize the tip with soap/water or alcohol wipe after each use to kill germs before storage or reuse.
Note Any Abnormalities
Record any symptoms along with temperature and monitor patterns over time. Consult your doctor if any readings cause concern.
With the proper technique, taking your temperature orally can provide quick and accurate insight into possible fever or illness. Make it part of your health self-monitoring routine.
Taking a Forehead Temperature
Measuring temperature using a forehead thermometer is a quick, non-invasive method. Here are tips on how to properly take someone’s temperature at the forehead or temporal artery.
Choose a Forehead Thermometer
Use an electronic thermometer designed specifically for the forehead. Look for an adjustable tip to fit all ages. Seek a model with a silent mode and large digital readout.
Read the Instructions
Read the manufacturer directions for proper use of your particular forehead thermometer model. Specific techniques can vary.
Clean the Thermometer
Before first use and between readings, clean the thermometer tip with an alcohol wipe or soap and water to prevent spreading germs.
Remove Hair, Sweat, Dirt
Gently brush away any hair, sweat or dirt from the center of the forehead to ensure good skin contact for accuracy.
Position Correctly
Have the person sit upright and bring the thermometer probe in contact with the center of the forehead, about an inch above eyebrows.
Press and Hold in Place
Press and hold the thermometer flush against the forehead skin for the required time, usually 10-15 seconds until it beeps.
Take 2-3 Readings
For best results, take 2-3 consecutive forehead temperature readings at the same session and use the highest measurement.
Note the Temperature
The digital display will show the temperature reading. Normal forehead temperature is 97.5-99.5°F (36.4-37.5°C).
Add Context
Note time of day, concurrent symptoms, recent medicines or activity that could impact the temperature.
Clean After Use
Disinfect the thermometer probe with an alcohol wipe after each use before storing it.
Minimize Error
Avoid taking forehead temperature after exercising, bathing, or being in direct sunlight which alter readings. Stay in draft-free room.
With practice, a forehead thermometer can provide a relatively quick and convenient way to assess for fever. Just be sure to use proper technique for most accurate readings.
Taking an Underarm Temperature
Measuring temperature under the arm (axillary) can be an alternative to oral readings. Here are some tips on properly taking underarm temperature.
Choose Underarm Thermometer
Use a digital thermometer designed for axillary use with a thin, flexible tip that can easily slip into the armpit.
Clean Thermometer Tip
Carefully clean the thermometer probe before each use with soap/water or alcohol wipe to prevent spreading germs.
Apply Some Powder
Lightly sprinkle some baby powder or cornstarch on the armpit. This allows smooth thermometer gliding and absorption of sweat.
Place in Armpit
Lift arm and insert the tip of the thermometer as far back into armpit as possible, adjacent to the body.
Lower Arm
Keep arm pressed tightly against the body and apply pressure against the body to keep thermometer firmly in place.
Hold In Place
Hold thermometer snugly in armpit for the required time until it beeps – usually 10 seconds for digital.
Read Temperature
Note the digital reading after it beeps. Normal underarm temperature is 97.5-99.1°F (36.4-37.2°C)
Repeat 2-3 Times
For accuracy, repeat the underarm process 2-3 times in a row and use the highest reading.
Both Underarms
Consider taking temperature in both underarms and comparing to account for any asymmetry.
Use Oral Too
For confirmation, also take oral temperature since underarm readings run about 1°F (0.6°C) lower than oral.
Disinfect After Use
Clean thermometer probe thoroughly with soap/alcohol to disinfect after each use before storage.
With practice, taking underarm temperature can be an easier option than oral, especially for young children. Just be sure to use proper technique.
Taking an Ear Temperature
Using an ear (tympanic) thermometer is a quick, non-invasive way to take someone’s temperature. Here are some tips for properly taking temperature through the ear canal.
Choose an Ear Thermometer
Use a thermometer designed specifically for the ear canal. Seek out a trusted brand with a reputation for accuracy and reliability.
Read the Instructions
Read the manufacturer’s directions for your particular model. Proper technique can vary between ear thermometer brands.

Press Button to Take Reading
With tip aimed at eardrum, press button to take reading. Measurement occurs very quickly, usually within 1-2 seconds.
Read Digital Temperature
The digital display will show the temperature reading. Normal ear temperature is 97.5-100.4°F (36.4-38°C).
Take 2-3 Times
For accuracy, repeat the ear temperature process 2-3 times per ear and use the highest reading.
Use Other Methods Too
Consider also taking oral or rectal temperature to confirm ear readings which can have more variability.
Note Time and Symptoms
Record date, time, symptoms, recent medicines or activities that could impact temperature.
Clean After Each Use
Disinfect thermometer probe with alcohol wipe after each reading before storage to prevent germ spread.
Watch for Problems
Avoid taking temperature after bathing, swimming, or lying down. Look for ear wax blockage, discharge, or infection prior to use.
With proper placement and technique, an ear thermometer can give fast temperature readings. Just be sure to use it correctly for optimal accuracy.
Caring for and Cleaning a Small Thermometer
Proper maintenance and hygiene are key to ensuring your small digital thermometer performs accurately. Here are tips for cleaning and caring for a digital stick thermometer.
Disinfect Between Uses
Always disinfect the thermometer probe before and after each use. Wash with soap and warm water or wipe with rubbing alcohol to prevent transmitting germs.
Store in Protective Case
Keep your thermometer in the provided protective case or storage sleeve when not in use. This prevents damage to the digital display and probe.
Avoid Extreme Temperatures
Don’t store the thermometer long-term in very hot or very cold environments like a car in summer or winter. Follow storage temperature guidelines.
Remove Batteries if Storing Long-Term
If storing for an extended period of time, remove batteries prior to storage. Batteries can corrode over several months if left in place.
Replace Batteries Annually
For optimal performance, replace batteries once a year even if the low battery light isn’t on yet. Weak batteries lead to inaccurate readings.
