Exposure to intense electromagnetic radiation, including infrared radiation, can damage the lens and cornea of the eye. The thermometer tells how hot a person is by measuring the infrared energy coming off the body. He said the Health Ministry (MOH) views seriously the claims that the usage of infrared thermometer for temperature checks, could cause brain damage, as viraled on social media. “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. Infrared thermometers work based on a phenomenon called black body radiation. Infrared therapy is a new and innovative light-based method to treat pain and inflammation in various parts of the body. The non contact infrared thermometer allows temperature to be taken without skin contact. Infrared Waves and Eye Damage. Most electronic thermometers have a digital display that shows you the temperature reading. [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. Sep 9, 2020. Infrared radiation damages the eyes and the skin and contributes to the greenhouse effect. These lasers can be strong enough to burn a hole through metal and so could certainly damage flesh. Large doses of infrared waves can also damage skin and tissues. This happens because the skin tends to become loose due to the constant ultraviolet rays. Some researchers have found the risk of infrared rays on sensitive body parts over some time. People who work in industries which expose them to infrared radiation for long periods of time may experience eye damage. "Human skin is a very good — or very efficient — emitter of infrared energy," says Gary O'Hara , chief technology officer for Sanomedics, which manufactures CareGiver, the brand of thermometer now being used in some airports. Even your body emits infrared waves of heat, which are detectable by thermal imaging machines. Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. 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. 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. The infrared thermometers, however, can be used on the wrist or elbow to measure the body temperature. She said: "Last night we made a totally unnecessary trip to the hospital thanks to a pretty expensive/crappy infrared thermometer. There is an increase in photoaging that leads to wrinkles and fine lines on y… “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. The outbreak of COVID-19 has placed the infrared thermometer in the limelight, as a preferred tool for fever detection. The most common kind of contact thermometer uses electronic heat sensors to record body temperature. Infrared laser thermometers are highly accurate, useful devices that have found applications in many different fields. Because a laser beam is involved, it is important to be very cautious during its use. People who work near intense radiation must wear goggles. Infrared radiation has a longer wavelength and lower frequency than visible light. Eye damage The human eye is sensitive to all radiation, including infrared radiation. Though the video claims using it on the wrist is more effect, health experts say the temperature will defer on different body parts. The higher the temperature, the faster the molecules move. 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. IR raises the internal temperature of the eye, virtually “baking” it. Ng DK, Chan C-H, Lee RS, Leung LC. Infrared radiation waves are the same as heat waves. A tweet claiming that infrared thermometers can cause damage to brain cells is MISLEADING. “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. Extremely powerful lasers are even being developed by the military for use as weapons. Laser beams are composed of highly amplified electromagnetic radiation (visible light, microwaves, infrared and others). Jeremy Cato is a writer from Atlanta who graduated with Phi Beta Kappa honors and an English degree from Morehouse College.

This infrared thermometer is used to avoid contact with people so that the virus doesn't spread. The publishers permit sharing of the paper's PDF on WhatsApp and other social media platforms. However, given their unreliability are the risks of damage to the eyes and pineal gland really worth it? This is one reason why staring at the sun is harmful (and unintelligent). For these thermometers to be marketed, the manufacturer must justify its correct and safe operation through calibration and precision tests beforehand. Some health care workers and patients reported sleep disturbances, including … However, the use of infrared … The pineal gland is a small endocrine gland in the brain. Infrared waves are involved in the greenhouse effect. “Infrared thermometers shouldn’t be pointed at … 1. No-contact forehead thermometers measure the temperature of the body based on the level of thermal radiation being emitted by the skin. As much as 65% of the rays can get inside your skin during the treatment, and this can be fatal for your body. According to these “testimonies”, taking a temperature using an infrared thermometer endangers the pineal gland, located in the brain. “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. It makes various devices possible and useful, including night vision goggles, lasers, thermographic cameras, communications devices and weather satellites. The message cautions the public against having the thermometer pointed directly at the head, and instead to have their temperature taken from other parts of the body … Non-contact approach may reduce the risk of spreading disease between people being evaluated On the electromagnetic radiation spectrum, infrared radiation is that which has a frequency lower than red light. 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. Ann Trop Pediatr. 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. This is one of the reasons why people use saunas, but it causes the body to lose its water. It produces melatonin, al serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. In theory they measure temperature from a distance to reduce the transmission of any infection. Osio CE, Carnelli V. Comparative study of body temperature measured with a non-contact infrared thermometer versus conventional devices. Otherwise known as infrared (IR) … 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. 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. 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. Infrared thermometers work by receiving the thermal radiation emitted by humans, not vice versa. The occurrence of water loss upon exposure to infrared radiation is almost automatic. 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. 15.
