On the electromagnetic radiation spectrum, infrared radiation is that which has a frequency lower than red light. Content on this site provides general information relating to health and is not intended to be a substitute for consultation. And, of course, aspirin and some other pain relievers can reduce body temperature, too, and mask a low fever. The infrared thermometers, however, can be used on the wrist or elbow to measure the body … A sensor relies on a silicon lens to focus the infrared energy so the reading isn't "of the wall, or of your hair," says O'Hara, "We want to read the temperature of a precise spot on your forehead." The result, he says, is a thermometer that matches an oral thermometer typically within two-tenths of a degree and ASTM International's thermometer standard to within four-tenths of a degree. The main concerns are the adverse psychological, physiological, and neurological effects of having a gun shaped-like device pointed to someone’s forehead daily and repeatedly. The Facebook message also says that pointing an infrared thermometer at the wrist instead of the forehead gives a more accurate temperature reading. The main concerns are the adverse psychological, physiological, and neurological effects of having a gun shaped-like device pointed to someone’s forehead daily and repeatedly. Some researchers have found the risk of infrared rays on sensitive body parts over some time. “Overexposure to infrared radiation can cause health problems such as skin burns and eye damage, but this is not an issue with infrared thermometers,” Dr Rangnathan added. On a global scale, trapped infrared radiation contributes to global warming. This is one reason why staring at the sun is harmful (and unintelligent). A nurse sent paramedics to her house and her daughter Aria was eventually taken to hospital as a precaution - where Marina learned an important lesson about thermometers after the baby's reading came back perfectly normal, much to her surprise. And in 2009, with prompting from the World Health Organization, airports checked the temperature of some travelers, looking for symptoms of H1N1 flu. Some medical experts believe that it is not safe to point the thermometers at the forehead, as its frequent exposure may lead to some health issues. “I think the genesis of this belief in the effect of the thermometer on the pineal gland comes from the fact that in reptiles and birds this gland is indeed just under the skull and contains photosensitive cells (and therefore sensitive to sunlight. "It's very accurate at measuring whatever it's pointed at," Levine tells Shots. "What have I learned? Exposure to intense electromagnetic radiation, including infrared radiation, can damage the lens and cornea of the … She said: "Last night we made a totally unnecessary trip to the hospital thanks to a pretty expensive/crappy infrared thermometer. Infrared radiation waves are the same as heat waves. Too much exposure can damage your eyes and skin. Copyright 2020 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. "Ours was reading 38.1 and only going as low as 37.4 for 24 hours. She added that doctors also advised her the best way to measure a baby's temperature is to use an underarm thermometer, as they are the most accurate. "Ours was reading 38.1 … It makes various devices possible and useful, including night vision goggles, lasers, thermographic cameras, communications devices and weather satellites. The other difference is the algorithm the machine uses in its translation. You will obey!!! Infrared radiation has a longer wavelength and lower frequency than visible light. But this infrared thermometer can is used on a human for a general-purpose medical where the temperature is measure on the human forehead. They took us in anyway just in case.". As the NPR blog Goats & Soda reported previously, there are pros and cons to different types of temperature-taking devices, from the fairly common ear gun thermometer to the full-body scanner. So there you have it folks, time to ditch your infrared thermometer and buy an underarm one instead. However, the CDC also notes that this particular type of fever detector is most accurate when measuring the temperature of dry skin, in a draft-free room. When the air above the earth's surface has a high concentration of water vapor, as well as elements such as sulfur and nitrogen and chemicals such as chlorofluorocarbons, the infrared radiation becomes trapped near the ground. Infrared thermometers do not emit radiation to the brain and pose no risk to the pineal gland. A standard infrared thermometer absorbs infrared but doesn’t emit it, so from that perspective they are safe. In this case, that's a forehead, which doesn't precisely reflect the human body's internal temperature, but is a close enough match for the rough purposes of screening, Levine says. In 2003, some Asian airports used thermometers as part of their screening of passengers for symptoms of severe acute respiratory syndrome, or SARS. CareGiver captures that energy coming off the body, and the device is calibrated to translate that energy reading into the temperature of an object. That's part of what differentiates a human no-touch thermometer from an industrial one, he says — the narrow field of view. People who work near intense radiation must wear goggles. People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. Even your body emits infrared waves of heat, which are detectable by thermal imaging machines. Some health care workers and patients reported sleep disturbances, including nightmares after daily forehead temperature checks. The earth's surface and the clouds above it absorb radiation from the sun's rays and re-emit it as infrared radiation back out into the atmosphere. You can unsubscribe at any time. "Ours was reading 38.1 … People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. No-touch thermometers are useful, in part, because they're unlikely to pass infection from person to person, according to the Centers for Disease Control and Prevention. Originally published on October 17, 2014 11:39 am. Large doses of infrared waves can also damage skin and tissues. The goal is to detect fever; for public screening purposes, according to guidance from the Centers for Disease Control and Prevention, an elevated temperature higher than 100.4 Fahrenheit (if you have reason to think you might have been exposed to Ebola) merits follow-up.
