英语课程计划-National Napping Day（在线收听）

National Napping Day started in 1999. It takes place on the Monday after daylight savings time begins, which is when a lot of people lose an hour’s sleep. The day serves as a reminder to us all that sleep is an essential and healthy part of our daily routine. More and more people are not getting enough sleep. We are working longer hours and there are more things to do that keep us awake, like movies and video games. National Napping Day raises awareness of the benefits of napping. Regular napping can reduce the risk of having a heart attack or suffering from other heart problems. It also increases our energy levels and improves our mood and performance. It is a very cheap way of making us feel better!

When we are deprived of sleep, the best thing to do is take a nap; get a bit of shut-eye; have forty winks. There is a lot of research into just what kind of nap is best for us. We all know about the traditional cat-nap. We put our head down and have a little sleep during our lunch hour. But then there is the power-nap. This is a short sleep which ends just before we fall into deep sleep. It quickly refreshes you and stops you from feeling drowsy and groggy. Another variety is the caffeine nap. This is when you have a power nap after a cup of coffee. It takes about 20 minutes for the caffeine to take effect, so when you wake up you feel doubly energized. Whatever nap you take, you can rest assured it will be good for your health.
