Screen time negatively impacts physical activity levels in children by promoting a sedentary lifestyle. Increased hours spent on televisions, computers, and gaming devices can lead to decreased active playtime, contributing to higher rates of childhood obesity and associated health issues. Studies show that excessive screen time is linked to lower overall fitness levels and diminished social interaction, which are essential for healthy physical and emotional development. Encouraging outdoor activities and limiting screen time helps maintain a balance, ensuring children stay active and engaged in their overall well-being.
