Scientists and doctors do not know for sure yet. There are no known side effects of using a medical grade IR forehead thermometer. Infrared thermometers work by receiving the thermal radiation emitted by humans, not vice versa. The infrared thermometer gun is commonly used in public spaces and offices on people before entering the premises. A tweet claiming that infrared thermometers can cause damage to brain cells is MISLEADING. On a global scale, trapped infrared radiation contributes to global warming. No-contact forehead thermometers measure the temperature of the body based on the level of thermal radiation being emitted by the skin. 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. This is then manipulated to provide the temperature reading. The same thing happens when you go for infrared heat therapy. 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. Because a laser beam is involved, it is important to be very cautious during its use. Unlike ultraviolet light, which can damage the skin, infrared … 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. There is no right way to use it, but pointing it on the forehead is a commonly practised by people all over the world. Is Far Infrared Harmful. 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. 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. 2. This happens because the skin tends to become loose due to the constant ultraviolet rays. Infrared waves are involved in the greenhouse effect. On the electromagnetic radiation spectrum, infrared radiation is that which has a frequency lower than red light. Jeremy Cato is a writer from Atlanta who graduated with Phi Beta Kappa honors and an English degree from Morehouse College. You may have seen people who are exposed to sunlight for long hours have wrinkled skin. Since these radiations have a heating effect on the skin and body, the body begins to sweat once it is exposed the radiations. Some health care workers and patients reported sleep disturbances, including … The detector used absorbs the thermal (IR) energy emitted from your forehead and converts that to a electrical potential. Most electronic thermometers have a digital display that shows you the temperature reading. Large doses of infrared waves can also damage skin and tissues. This makes it a hygienic method to take the temperature of different people. 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. 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 … People who work near intense radiation must wear goggles. These waves have longer wavelengths than visible light and make up a greater portion of sunlight than visible light and ultraviolet radiation. 1. The use of infrared thermometers has become a routine practice as a preventive measure to filter out a suspected fever. The electronic circuit within the thermometer processes the electrical signal to determine the temperature and display the reading on a screen. Infrared heaters are available with three types of heating elements: 1. halogen; 2. carbon; 3. ceramic. 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. 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. According to these “testimonies”, taking a temperature using an infrared thermometer endangers the pineal gland, located in the brain. The thermometer tells how hot a person is by measuring the infrared energy coming off the body. 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. IR raises the internal temperature of the eye, virtually “baking” it. For these thermometers to be marketed, the manufacturer must justify its correct and safe operation through calibration and precision tests beforehand. 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. 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. 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 ..

This is one reason why staring at the sun is harmful (and unintelligent). The publishers permit sharing of the paper's PDF on WhatsApp and other social media platforms. 16. Some researchers have found the risk of infrared rays on sensitive body parts over some time. 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. Exposure to intense electromagnetic radiation, including infrared radiation, can damage the lens and cornea of the eye. 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. 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. Since the coronavirus outbreak, health experts says many false claims have surfaced online. Osio CE, Carnelli V. Comparative study of body temperature measured with a non-contact infrared thermometer versus conventional devices. 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. These posts have been shared nearly 6,000 times on Facebook since the end of June. "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. Don't stare at the sun! Infrared thermometer eye damage. Eye damage The human eye is sensitive to all radiation, including infrared radiation.
