A recent class survey shows that Grade 8 students spend an average of 2.5 hours per day on their phones—mostly on social media and games. Alarmingly, over 60% get less than 8 hours of sleep, and nearly half admit they feel tired in class. These numbers reveal a serious issue: digital overuse is affecting our health and learning. While phones help us stay connected, excessive screen time harms concentration and sleep quality. I suggest setting daily limits—no more than one hour for entertainment. Also, try the “20-20-20 rule”: every 20 minutes, look at something 20 feet away for 20 seconds. Let’s use technology wisely, not let it control us.
