Screen Curfew Recommendation
Prof. Dr. Arslan advises avoiding digital devices at least 3–4 hours before sleep. Occasional brief use is fine, but prolonged exposure until bedtime prevents natural sleep onset and may lead to reliance on sleep aids or relaxation teas. For example, if bedtime is 11 p.m., stop using screens by 9–10 p.m.
Limit and Monitor Screen Use
Maintaining a proper viewing distance (40–60 cm) and limiting exposure is crucial, as prolonged blue light harms both eye and overall health. Children are especially sensitive: 0–2-year-olds should avoid screens entirely, while 2–5-year-olds should limit use to 40–60 minutes daily. Excessive screen time can negatively affect attention, learning, and sleep quality.
