A recent viral video shows a man speaking about the harmful effect of the infrared thermometer guns, which are being used all over the world to monitor temperature amid the coronavirus outbreak. ). 4 min read. 3. “On a daily basis we come across many forms of radiation, but it doesn’t mean it will affect any part of the body or glands. (To download our E-paper please click here. Chennai-based scientist Dr S Rangnathan said there is no such evidence to show that the pineal glands are being damaged because of the infrared thermometer. On a global scale, trapped infrared radiation contributes to global warming. Infrared thermometers work based on a phenomenon called black body radiation. The infrared thermometer gun is commonly used in public spaces and offices on people before entering the premises. The same thing happens when you go for infrared heat therapy. “Infrared thermometers shouldn’t be pointed at … The non contact infrared thermometer allows temperature to be taken without skin contact. The thermometer tells how hot a person is by measuring the infrared energy coming off the body. This happens because the skin tends to become loose due to the constant ultraviolet rays. The electronic circuit within the thermometer processes the electrical signal to determine the temperature and display the reading on a screen. There are many published clinical studies of the biological effects of (FIR) far infrared rays on the US National Library of Medicine.. From years of experience and hundreds of thousands of sales, I can honestly tell you, there has been only a couple of times a customer was concerned about what they thought was a negative side effect. This is one of the reasons why people use saunas, but it causes the body to lose its water. However, the use of infrared … Infrared waves are incredibly versatile, but they can also be dangerous. The most common kind of contact thermometer uses electronic heat sensors to record body temperature. And, since the gun is pointed at the forehead to take the temperature, the person claimed it can damage the pineal gland in the brain. Most electronic thermometers have a digital display that shows you the temperature reading. Too much exposure can damage your eyes and skin. Infrared radiation is a form of electromagnetic radiation which is found just outside the visible portion of the spectrum, before the color red 1. Ng DK, Chan C-H, Lee RS, Leung LC. Infrared thermometers work by receiving the thermal radiation emitted by humans… The detector used absorbs the thermal (IR) energy emitted from your forehead and converts that to a electrical potential. Eye damage The human eye is sensitive to all radiation, including infrared radiation. The occurrence of water loss upon exposure to infrared radiation is almost automatic. Large doses of infrared waves can also damage skin and tissues. Some health care workers and patients reported sleep disturbances, including … Infrared heaters are available with three types of heating elements: 1. halogen; 2. carbon; 3. ceramic. 16. The halogen emitter has two drawbacks - its golden light irritates the eyes and it radiates short-wave heat, which has a negative effect on a person. People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. The higher the temperature, the faster the molecules move. The use of infrared thermometers has become a routine practice as a preventive measure to filter out a suspected fever. No-contact forehead thermometers measure the temperature of the body based on the level of thermal radiation being emitted by the skin. In theory they measure temperature from a distance to reduce the transmission of any infection. Infrared Waves and Eye Damage. You may have seen people who are exposed to sunlight for long hours have wrinkled skin. IR raises the internal temperature of the eye, virtually “baking” it. The infrared radiation can penetrate the human body into the dermis before absorption. People who work near intense radiation must wear goggles. As they move, the molecules emit infrared radiation--a type of electromagnetic radiation below the visible spectrum of light. In addition to thermal radiation, a carbon heating element gives off some energy in the form of a reddish glow, which can be an irritating factor for the eyes and cause a negative reaction in asthmatics and allergies. Unlike ultraviolet light, which can damage the skin, infrared … This is one reason why staring at the sun is harmful (and unintelligent). There are no known side effects of using a medical grade IR forehead thermometer. 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. Exposure to intense electromagnetic radiation, including infrared radiation, can damage the lens and cornea of the eye. As much as 65% of the rays can get inside your skin during the treatment, and this can be fatal for your body. But, till there are specific studies that claim or prove otherwise, it is hard to say whether the infrared thermometer gun can affect the human brain. However, in recent days, began to spread on the social networks, the risk it poses to the eyes to be exposed to this tool, noting that the device works on the basis of a laser beam. Non-contact approach may reduce the risk of spreading disease between people being evaluated However, given their unreliability are the risks of damage to the eyes and pineal gland really worth it? > 1. So far the thermometer gun has been commonly used on the forehead. The claim is false; experts say infrared radiation in the guns does not harm the brain; health agencies worldwide encourage using thermometer guns to manage the spread of COVID-19, the disease caused by the … These posts have been shared nearly 6,000 times on Facebook since the end of June. The publishers permit sharing of the paper's PDF on WhatsApp and other social media platforms. For these thermometers to be marketed, the manufacturer must justify its correct and safe operation through calibration and precision tests beforehand. “A study conducted by MOH Health Technology Assessment Branch, found no scientific evidence on the side effects of taking forehead temperature using infrared thermometers,” he said. 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. Measurement error generally only decreases with too much distance because of the effects of reflectivity and the inclusion of other heat sources within the sensor's field of view. The infrared thermometers, however, can be used on the wrist or elbow to measure the body temperature. Infrared therapy is a new and innovative light-based method to treat pain and inflammation in various parts of the body. "Ours was reading 38.1 … The Infrared Thermometer does not use a laser beam to measure a person's temperature but uses infrared rays that detect body temperature without impacting the retina. Find patient medical information for Clever Choice Infrared Thermometer on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings. It makes various devices possible and useful, including night vision goggles, lasers, thermographic cameras, communications devices and weather satellites. It produces melatonin, al serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. Laser beams are composed of highly amplified electromagnetic radiation (visible light, microwaves, infrared and others). Prolonged IR exposure can lead cataracts, corneal ulcers, and retinal burns. Is Far Infrared Harmful. “Although no substantial studies have come out indicating the harmful effects, in hospitals the forehead is used to measure the temperature, while … The detector is passive and does not require an electrical power to it. Infrared radiation is invisible but the energy of this region happens to correspond to the approximate level of energy needed to start molecules moving in various ways. This causes elevated temperatures and changes in weather patterns that can be harmful to people and animals. An infrared thermometer has a lens that helps you focus on the desired object while infrared rays are used to measure the amount of heat generated by the body or an object. These lasers can be strong enough to burn a hole through metal and so could certainly damage flesh. There is an increase in photoaging that leads to wrinkles and fine lines on y… She said: "Last night we made a totally unnecessary trip to the hospital thanks to a pretty expensive/crappy infrared thermometer. Infrared thermometers work by receiving the thermal radiation emitted by humans, not vice versa. Heating elements with a ceramic shell do not e… A Facebook post shared thousands of times claims that taking a person’s temperature with an infrared thermometer near their head risks damaging the pineal gland, which is located in the brain. Ann Trop Pediatr. Sep 9, 2020. This infrared thermometer is used to avoid contact with people so that the virus doesn't spread. A tweet claiming that infrared thermometers can cause damage to brain cells is MISLEADING. Infrared thermometers have produced lower readings in lab tests meant to simulate athletic settings than other devices, which could deprive patients of critical care. 2. But can it? Infrared radiation has a longer wavelength and lower frequency than visible light. Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. 2005;25:267-75. Laser thermometers advantages. There is no noticeable side effect, not from the (optional) red laser dot ( very low power and must defacto be save to your eyes too ) and the real IR reader only reads what infra-red heat you emits, so nothing is radiated towards your body except that little red laser dot. The pineal gland is a small endocrine gland in the brain. According to these “testimonies”, taking a temperature using an infrared thermometer endangers the pineal gland, located in the brain. Infrared radiation waves are the same as heat waves. Anything at a temperature above absolute zero has molecules inside of it moving around. This makes it a hygienic method to take the temperature of different people. A video has been viewed thousands of times on Facebook and YouTube alongside a claim that thermometer guns cause “damage” to the brain because they contain infrared radiation. [citation needed] An infrared thermometer cannot be placed too close to its target, or this proximity causes heat to build up in the thermometer's housing and damages the sensor. An infrared laser thermometer is a device that can measure the temperature of an object in the vicinity by pointing a laser beam at it. 1. Jeremy Cato is a writer from Atlanta who graduated with Phi Beta Kappa honors and an English degree from Morehouse College. The human eye is sensitive to all of the radiation in the electromagnetic spectrum, especially if that radiation is at very high levels of intensity. "It is designed to detect and absorb heat in the form of infrared rays emitted from the human body and convert it into electricity. NASA Earth Observatory: Clouds and Radiation, University of Chicago Press: The First Laser. Infrared thermometer eye damage. The tweet contains an image with text claiming that the radiation from temperature guns kills neurons, which the post misspells as ‘neutrons’, and can lead to brain damage. People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. But, what can really damage the eye health? This is then manipulated to provide the temperature reading. Though the video claims using it on the wrist is more effect, health experts say the temperature will defer on different body parts. Suresh Kakani, Additional Municipal Commissioner, BMC said they have not come across a case where a person's pineal gland was affected due to the use of an infrared thermometer. Otherwise known as infrared (IR) … On the electromagnetic radiation spectrum, infrared radiation is that which has a frequency lower than red light. 15. 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. 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. They don’t really need to be brought in contact with the object whose temperature needs to be measured , Laser thermometers can measure temperature from a remote location and it is only necessary that the path of the laser shouldn’t be obstructed .. Forearm peripheral temperature will be less and that’s why forehead is chosen.” “Prolonged exposure to sun’s infrared rays is harmful but measuring body temperature with infrared thermometers is a transient one and will not harm in the short run,” said Dr Renchy.
