Normal forehead skin temperature can vary several degrees depending on your environment (indoors or out), exercise, perspiration, direct heat or air conditioning, etc. It would be normal to read an actual forehead skin surface temperature between 91F and 94F if using a general-purpose infrared thermometer.
The average forehead temperature was 34.90 ± 1.49 °C after 1 min, 35.77 ± 1.10 °C after 3 min, 36.08 ± 0.79 °C after 5 min and 36.60 ± 0.24 °C after 1 h. Our empirical findings suggest that the timing of measurement was important (Table 2).
In the age of COVID, our forehead will become the target of fever spot checks. Thermal cameras and non-contact infrared thermometers will get deployed in an effort to prevent people with a fever from entering into an area where they may infect others.
An armpit (axillary) temperature is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature. A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.
They are easily administered and can be used on infants, children, and adults. Some research indicates that temporal thermometers may be as accurate as rectal thermometers in children, and provide better readings than ear or armpit thermometers can.
It would be normal to read an actual forehead skin surface temperature between 91 ° F and 94 ° F if you use a general-purpose infrared thermometer.
The Braun Digital No-Touch Forehead Thermometer was by far the best we tested. This thermometer guides you through the entire temperature-taking process with directions conveniently printed right on the front of the thermometer.
To use the forehead thermometer, a person should hold the sensing area perpendicular to the forehead at the distance that the manufacturer recommends. A person should then hold the thermometer steady and ask the subject to stay still to take their temperature.
A temporal thermometer will read at about 0.5 to 1 degree lower than an oral thermometer, so you need to add 0.5 to 1 degree to get what your temperature would read orally. For example, if your forehead temperature read as 98.5°F, you could actually have a low-grade fever of 99.5°F or higher.
If the thermometer doesn't have the adjusted mode, it's designed for industrial thermometry applications with a wide temperature range. If you don't have this adjusted mode you get a reading that's about 3 °C (5.4 °F) low, because of the difference between skin and body core temperature.
The temperature is measured on the lateral side of neck, which lies closer to large arteries (carotid artery) than do the temporal arteries of the forehead region. Thus, neck IFR measures closely reflect axillary temperatures.
In conclusion, our study shows that commercially available, handheld infrared thermometers require individual validation. Forehead temperature in excess of 35.6°C (96.1°F) is suggestive of fever. Further studies are required to confirm accuracy of this value in detecting fever.
The most basic model is the ThermofocusÒ 0700A2, which can be used to measure temperature by holding the thermometer over the central forehead. Thermometers in the ThermofocusÒ 01500 series can also be used to measure temperature over other areas of the body, including the neck, umbilicus and axilla.
People may feel hot without a fever for many reasons. Some causes may be temporary and easy to identify, such as eating spicy foods, a humid environment, or stress and anxiety. However, some people may feel hot frequently for no apparent reason, which could be a symptom of an underlying condition.
Hormonal fluctuations, thyroid problems, or heat-related disorders like heat exhaustion and heat stroke are possible causes of a head that feels hot. If your head feels warmer recently and you have other accompanying symptoms, it's important to seek medical help.
The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. Your body temperature can vary depending on how active you are or the time of day. Generally, older people have lower body temperatures than younger people have.
Share on Pinterest A person's forehead may feel very hot when they have a fever. Many people can recognize when they feel feverish. Some describe it as a feeling of warmth.
