Prolonged exposure to high levels of infrared radiation could lead to burns and cause eye problems, including cornea and retina damage, cataracts and injuries to the eye lens. In addition, infrared radiation can cause pain to the skin of a person in close contact with it.
Most infrared radiation is not visible and may affect a person without his knowledge. Similarly, some radiation is neither hot nor colored, making them difficult for people to detect and avoid.
In the electromagnetic spectrum, infrared rays are just below visible red light. Many objects, including lamps, flames, stars and other warm items, emit these rays. They are most commonly used in mobile phones, in remote controls for TV sets and in other short-range communication devices. In addition, physiotherapists use infrared technology to help the healing of athletes' injuries.
Modern weapons have infrared detectors that are designed to spot targets, particularly at night. Although occasional exposure to these rays is not enough to cause danger, everyday contact can cause long-term health problems. Employees working for companies involved in the mass production of lasers and heat lamps have a higher risk of experiencing adverse effects due to exposure. These rays can disrupt body cells, penetrate DNA and cause cancer. Those who are vulnerable are advised to wear protective gear.
