Never Let the Computer’s “Back” Face People
People who work long hours on computers often suffer eye dryness, facial itching, and headaches—commonly blamed on screen radiation. Actually, the strongest electromagnetic radiation comes from the computer’s “back” and sides. Experts warn users: never let the computer’s “back” face anyone.
Computer screens use leaded glass to block some radiation, but the sides and rear lack shielding. Facing these areas exposes people to unblocked radiation. In many offices, computers are stacked closely to save space, with no barriers to block radiation—posing serious health risks to those seated in front. Multiple computers create cumulative radiation effects. Long-term exposure may lead to headaches, facial itching, insomnia, loss of appetite, and low mood.
For women, electromagnetic radiation harms reproductive function and fetal development, potentially increasing breast cancer risk.
Experts advise: safest placement is to position the computer’s back against a wall, with at least 1 meter between machines. If space is limited, keep at least 1 meter distance from the computer’s back.
· Maintain hygiene: Don’t eat while using the computer; wash hands after work.
· Keep skin clean: Regularly clean face and hands.
· Supplement nutrition: Eat more fruits, milk, and other foods rich in vitamin A and protein.
· Maintain correct posture: Eyes should be 40–50 cm from the screen.
· Optimize workspace: Avoid overly bright or dim lighting; prevent direct light from hitting the monitor.
· Balance work and rest: Take a 10-minute break every hour and do eye exercises.
