Q

Dear Daniel

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

Heater

A

Dear Heater，

This is a serious problem. As a teacher，I saw many students sleeping in class，【小题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 【小题3】（study）.Research shows that studying【小题4】you're tired is less effective. 【小题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 【小题6】（wide）awake. If you 【小题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. 【小题8】（drink）non-caffeinated teas or water.

As 【小题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 【小题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

Has anybody ever told you that you shouldn't sneeze（打喷嚏）with your eyes open and your eyeballs will pop out？This might sound reasonable，because our eyelids（眼皮）always close when we sneeze. But is that true？

Actually，this is highly likely. Although a sneeze can burst from your nose in a speed of 320 kilometers per hour，it can't transfer（转移）that pressure to your eyes. Plus，there's no muscle directly behind the eye what could push the eyeballs outward. Thus，your eyelids don't have much muscle power，so even if they are responsible for keeping your eyeballs in place，they would fail.

But then why do we always close our eyes when we sneeze？It's simple a reflex（反射）of the body，just like how our legs kick when our knees tapped. The nose and eyes are linked by nerves. so the stimulation（刺激）from the sneeze travel up one nerve to the brain then down another nerve to the eyelids，cause a blink（眨服）for most people. It's just an involuntary reaction with no real purpose.
