March 16 is International Sleep Day. And we should all celebrate the act of sleeping. Researchers say sleep is probably the best tool we have for memory and learning. But what about getting rest during the middle of the day?
A recent study on napping(小睡) says short periods of sleep may help our brains work better. Past studies have shown that napping can help babies and young children learn better. And napping can help brain performance in older adults. Taking a nap may also help this group of people fight off memory loss because of the increase in their age.
Many Americans do nap. But one-third of all adults in the United States are also chronically(长期的) tired, says the U.S. Centers for Disease Control and Prevention (CDC). It found that 50 million to 70 million Americans have chronic sleep disorders. However, they seem to be unwilling to tell people that they take a nap. They may think that napping shows they are weak or they don’t have enough energy. It is not an uncommon opinion that only children, the very old, sick or lazy people nap. In fact, Americans sometimes do a very strange thing. Some people brag about how few hours of sleep they need each night to show that they are somehow stronger than the average human–superhuman, if you will. However, that may be changing. Many offices now offer napping rooms and napping cafes(咖啡馆) are appearing in many U.S. cities, including Washington, D.C.
Remember that an hour long nap may be too long for young, healthy adults. It is recommended that 30 minutes is enough to remove the pressure(压力) to sleep and will help people feel more awake. If people nap longer, they will get trapped into deep sleep, which can be hard to get out of. If you have trouble falling asleep at night, limit your daytime nap to under 45 minutes. Also nap before 3 p.m.
