周三晚会直播讲题（同行免入）
C
Many teenagers today spend too much time on their smartphones. Whether they are playing games, chatting with friends, or watching short videos, this habit can lead to serious sleep problems. According to a recent health report, over 60% of middle school students do not get the required eight hours of sleep.
Experts suggest that the blue light from screens tricks the brain into thinking it is still daytime, making it difficult to fall asleep. To solve this problem, doctors advise putting away all electronic devices at least an hour before bed. Instead of looking at a screen, teenagers can try reading a physical book, listening to soft music, or simply relaxing.
Reducing screen time before sleep can not only help you rest better but also improve your memory and attention in class the next day. A good night's sleep is the foundation of a healthy lifestyle and better academic performance.
