Health Experts Warn of Widespread Risks from Evening Screen Time

Experts say that blue‑light exposure from phones, tablets, TVs and computers before bedtime disrupts melatonin production, making it harder for children to fall asleep, stay asleep and obtain restorative sleep. The effects can include longer time to fall asleep, shorter overall sleep duration, increased bedtime resistance and daytime fatigue, which in turn may affect mood, focus and school performance. Recommendations for families include establishing a “no screens” rule 30–60 minutes before bed, keeping devices out of bedrooms overnight, using parental controls or timers, and replacing screen use with calming activities such as reading physical books or gentle stretching.

For adults and other screen‑heavy professionals, prolonged device use is linked to digital eye strain or computer‑vision syndrome. Roughly 60 % of U.S. adults report eye‑related discomfort, with symptoms such as dry eyes, blurred vision, headaches and neck pain. The average adult spends over ten hours daily on screens, and remote workers may exceed 13 hours. Health professionals advise regular eye examinations, proper monitor distance (20–26 inches) and placement (at or below eye level), frequent short breaks, and managing screen time to reduce strain.

Both sets of guidance aim to mitigate the long‑term health impacts of excessive screen exposure, emphasizing routine, moderation and professional monitoring.
