阅读下面材料，从题中所给的 A、B、C、D 四个选项中选出一个最佳选项。
Many students enjoy staying up late to play on their phones or study. However, doctors tell us that this is very harmful to our health.
First, staying up late affects your body. When you don't get enough sleep, you may feel very tired and get a headache the next day. Your immune system becomes weaker, which means you are more likely to get sick, like catching the flu. More importantly, staying up late for a long time can make your stomach uncomfortable and even cause a stomachache.
Second, staying up late also influences your mood and studies. You may find it hard to concentrate at school the next day. You might feel unhappy or impatient. If you always stay up late, you might even feel more anxious and stressed.
So, what should you do? You should set a fixed bedtime for yourself. You could read a book to relax before sleep instead of using your phone. If you have a lot of homework, you should try to finish it more efficiently(高效地) during the day instead of leaving it until late at night.
Remember, it is very important to take good care of yourself. A good sleep can help you stay healthy and happy.
