单项选择题英语练习题

Sleep is very important for our health. During sleep, our body repairs itself and our brain organizes the things we learned during the day. Adults need about seven to eight hours of sleep every night. But many people do not get enough sleep. Some stay up late working, and others spend hours playing games or watching videos on their phones. Long-term lack of sleep can cause many health problems. People may easily get angry, feel tired, and even fall ill. Good sleep habits are necessary. First, go to bed and get up at the same time every day. Second, do not drink coffee or tea before bed. Third, keep the bedroom dark and quiet. If you cannot sleep, do not worry too much. Reading a book or listening to soft music may help you fall asleep. A short afternoon nap of twenty minutes can also make you feel fresh again.

What may happen if people lack sleep for a long time?
