Read the passage and decide if the statements are True or False.
Many teenagers use screens late at night to chat, watch videos, or play games. However, research shows that heavy screen time in the evening can reduce sleep quality. First, blue light from phones and tablets makes it harder for the brain to release melatonin, the hormone that helps us feel sleepy. Second, exciting content keeps the mind active and delays bedtime. As a result, students may sleep fewer hours and feel tired in the morning, which can affect memory, mood, and attention in class.
There are simple ways to improve sleep: set a “digital curfew” at least one hour before bedtime, switch devices to night mode, and keep phones outside the bedroom. Doing relaxing activities—such as reading a paper book, stretching, or taking a warm shower—can also help the body prepare for rest. While screens are useful for learning and staying connected, using them wisely in the evening is important for healthy sleep.
