Q

Dear Daniel

My high school life is     1     （stress）. I try to sleep for a while at noon，but I still get sleepy in the afternoon. What should I do？

Dear Heater，

This is a serious problem. As a teacher，I saw many students sleeping in class，    2    （able） to focus-even children！

Let's look at your lifestyle. Do you stay awake late at night？Do you use your smartphone before bed？Do you have caffeine at night？

First，late nights are a bad habit，even if you're staying up late     3    （study）.Research shows that studying    4    you're tired is less effective.     5     （lose）sleep makes you too tired in class the next day. You should sleep for seven or eight hours each night.

Next，don't use your smartphone before bed. The screen keeps our eyes and brains       6    （wide）awake. If you     7    use a phone before bed，use a blue-light filter（过滤）app.

Of course，you should avoid caffeine after dinner. This means no cola，no chocolate and no coffee.     8    （drink）non-caffeinated teas or water.

As     9    your sleepy afternoons，napping（午休）is normal and healthy. It sounds like you need a "power nap”. These are 20-30 minute naps that give a boost（增强）of energy. Set your alarm for 25 minutes and get up when you hear it. Be careful！If you nap too long，you will feel     10    （sleep）than before.

Proper sleep is an important part of a healthy life，so taking a nap is taking care of yourself.

Good luck！

Daniel
