Infrared thermometers might be 'hygiene theatre

    The infrared thermometers increasingly being used as COVID-19 screening measures at Canadian entry points and businesses are not able to catch every case of the novel coronavirus, but there is no reason to believe they will harm your brain.To get more news about Face infrared thermometer, you can visit jiminate official website.

    That latter claim has been circulating on social media in recent weeks, including in a video that has garnered more than two million views since it was posted to YouTube on Aug. 11. In the video, a man shares a social media postof which he says he does not know the origin, attributed to "an Australian nurse" for whom no name is given.

    The author of the post says that "an infrared thermometer must never be pointed at someone's forehead, especially babies and young children," but does not provide any evidence to back that up. He or she seems especially concerned with the pineal gland, a small organ that produces melatonin and other hormones, but does not explain why that the gland is in any way affected by the use of forehead-scanning thermometers. That, experts say, is because there is no evidence. "There's zero truth to that claim," Dr. Isaac Bogoch, an infectious disease specialist with Toronto's University Health Network, told CTVNews.ca on Thursday via telephone. "I honestly don't know what to say about it. It's insane, it's wrong, and it's crazy that something like this could still be amplified and even believed.

    " Moreover, while the post quoted in the video expressed concern about "infrared rays" coming from thermometers, infrared thermometers do not transmit any rays or any other form of radiation; they only measure infrared wavelengths coming from the body. "It's not sending any kind of signal," Dr. Haris Sair, director of neuroradiology at Johns Hopkins University, told The Associated Press in July. Additionally, Sair said, the thermometers measure temperature at the body's surface – not several centimetres into the brain, where the pineal gland is located.

    The Australian Associated Press reported Aug. 25 that similar claims had been made in widely-circulated posts on Facebook and Instagram. The Instagram post it referenced has since been flagged by the platform as containing verifiably false information. Infrared thermometers are considered to be more expensive and less accurate than those that measure body temperature by being inserted into the mouth. However, many businesses have chosen to use them because the lack of direct contact means they do not need to be sanitized every time they are used on a new person. Temperature checks with these thermometers have been mandatory at Canadian airports since June. Temperature checks do not catch all COVID-19 patients, though, missing those who are asymptomatic as well as symptomatic patients who do not count fever among their symptoms.
