How much screen time is too much?
For adults, research suggests negative effects (sleep disruption, anxiety) kick in above 4–5 hours of recreational screen time per day. Work-related screen time has different impacts. Quality matters as much as quantity.
What's the most effective way to reduce screen time?
Use your phone's built-in app limits (Screen Time / Digital Wellbeing), remove social apps from your home screen, enable grayscale mode, charge your phone outside the bedroom, and replace the habit with a physical activity.
Does screen time affect sleep?
Yes — blue light from screens suppresses melatonin production. Using screens in the hour before bed delays sleep onset by 30–60 minutes on average. Night mode helps slightly but the stimulation itself is also a factor.
