cause of RSI

repetitive movements, muscle overuse

prevention of RSI

taking regular breaks, using ergonomic equipment, and correct typing posture

cause of back and neck strain

poor posture, long monitor use

prevention of back and neck strain

use adjustable chair, footrest, tiltable screen

cause of eyestrain

prolonged screen time, bad lighting

prevention of eyestrain

use LCD screens, anti-glare filters, take breaks, regular eye tests

cause of headaches

flickering/reflected light, poor lighting

prevention of headaches

use anti-glare screens, correct lighting, regular breaks

cause of ozone irritation

ozone from laser printers

prevention of ozone irritation

ensure ventilation, isolate printers, use inkjet alternatives
