Watching excessive TV is a major problem, as blue light disrupts sleep and raises depression risk by up to 40%. Binge-watching leads to social isolation and poor physical health. The solution is limiting screen time to 1–2 hours daily, replacing TV with hobbies or exercise, and following a "no-screen" bedtime rule. The benefit is immediate: reducing TV by just 1.5 hours lowers depression risk by 26%, while boosting mood, mental focus, and restorative sleep.
