Parents should strictly limit their teens' screen time for several reasons. Excessive use can negatively impact teens' academic performance, as they may spend too much time in front of screens, neglecting their schoolwork and avoiding outside activities. In addition, prolonged exposure to screens can result in negative health effects such as damage to eyesight, headaches, and weight problems. Parents play a crucial role in controlling the time their teens spend on digital devices to ensure a balanced and healthy lifestyle. By setting reasonable limits, parents can promote focus on academic responsibilities and promote overall well-being.
