Myth: Infrared thermometers that take your temperature without touching your body can damage the brain
This is not true. These thermometers use infrared waves to take your temperature. These are the same kinds of waves used by your television remote control. Some rumors say these infrared thermometers cause blindness and that they damage glands in the brain. These rumors are not true. These kinds of thermometers read the temperature at the surface of your body and use a calculation to convert this into your internal temperature. Some infrared thermometers use a laser, but this is not what is taking your temperature. The laser helps the person using the thermometer know they are aiming it at the right part of the body.
