Can too much screen time affect a child's sleep?

Yes, excessive screen use can interfere with both bedtime and sleep quality. Phones, tablets, televisions and games can keep children mentally stimulated when they should be winding down. Screen use also tends to delay bedtime because children lose track of time or resist stopping. Bright light from devices may reduce the body's normal evening sleep signals, particularly when screens are held close to the face. Turn off screens at least one hour before bedtime and keep devices out of the bedroom overnight. Replace them with reading, drawing, quiet music or conversation. Daytime screen limits can also protect time for physical activity. If a child needs a device for homework, encourage them to finish earlier and reduce brightness where practical.
