Never Let the Computer’s “Back Head” Face People
People working long hours on computers often experience dry eyes, itchy face, and headaches—commonly blamed on screen radiation. In reality, the strongest electromagnetic radiation comes from the computer’s “back head” and sides. Experts advise users: never let the computer’s rear face anyone.
Computer screens are made of leaded glass, blocking some radiation. However, the sides and back lack shielding. Facing these areas exposes people to unblocked radiation. In many offices, computers are stacked closely together to save space, with no barriers to block radiation. This poses serious health risks to those seated in front. Multiple computers may create cumulative radiation effects. Long-term exposure may lead to headaches, facial itching, insomnia, loss of appetite, and low mood.
For women, electromagnetic radiation not only harms reproductive function and fetal development but may also increase breast cancer risk.
Experts recommend placing computers with their “backs” against walls, keeping at least 1 meter between units. If space is limited, maintain at least 1 meter distance from the computer’s back.
· Maintain hygiene: Avoid eating while using the computer. Wash hands after work.
· Keep skin clean: Regularly cleanse face and hands.
· Supplement nutrition: Eat more fruits, milk, and other foods rich in vitamin A and protein.
· Maintain proper posture: Keep eyes 40–50 cm from the screen.
· Optimize workspace: Avoid overly bright or dim lighting; prevent direct light from shining on the monitor.
· Balance work and rest: Take a 10-minute break every hour and perform eye exercises.
