Nowadays, many students spend too much time on electronic devices, which brings several serious problems to their physical and mental health. First of all, staring at screens for long hours can easily damage eyesight and cause poor posture. In addition, constantly checking short videos or online games reduces the ability to concentrate, leading to lower academic performance. Moreover, real-life communication skills may grow weaker because teenagers prefer texting to talking face-to-face. Therefore, it is highly suggested that we should limit daily screen time and take part in more outdoor sports instead.
