Dear Sir,
Although mobile phones are an essential part of modern life, their excessive and uncontrolled use is creating serious physical health hazards. These effects develop gradually and often go unnoticed until significant damage has occurred.
Research shows that prolonged screen exposure reduces the normal blinking rate, causing eye strain, dryness, blurred vision, and headaches-commonly known as digital eye strain. Blue light from screens can also harm the retina and may increase the long-term risk of vision problems, particularly in children.
Mobile phone use also affects posture. When the head tilts forward while viewing a screen, extra pressure is placed on the neck and spine. Over time, this can lead to neck pain, shoulder strain, and conditions such as text neck syndrome and early spinal disorders.
Moreover, screen exposure at night suppresses melatonin, disturbing sleep patterns and increasing risks of insomnia, heart disease, and weakened immunity. Excessive use also promotes physical inactivity, contributing to obesity and other lifestyle diseases.
Therefore, responsible use, regular breaks, proper posture, and limiting screen time before bed are essential to protect our health.
