You’d think the human race would have understood sleeping very well by now, but many of us are still sleeping poorly. Part of the problem is that we have wrong information and beliefs about this important health need. Let’s set the facts straight. 1.

1. More sleep is better for you.

There could be such a thing as too much sleep. The amount of sleep we need varies by person and also changes as we age. Harvard researchers found that a lot of sleep (9 hours or more) is linked with poor sleep quality. 2. Aim for better sleep.

2. 3.

Alcohol can help most people fall asleep. However, it also can cause you to wake up more during the night, decreasing your sleep quality. Consider drinking non-alcoholic drink before bed instead.

3. If you wake up in the middle of the night, lie in bed until you eventually fall back asleep.

4. We all hope to quickly fall back asleep. So we tend to stay in bed hoping it’ll happen at any minute now. If that doesn’t happen, though, within 15 minutes, most experts recommend getting out of bed to do something that occupies our bodies and brains without overstimulating us. Try not to check the clock either.

.4. You can catch up on sleep on weekends.

When we lose sleep during the week, we accumulate a kind of sleep ＂debt＂. 5.     Not so fast. This might actually make you sleepier the next week. Instead of waking up later on the weekends, you’d better go to sleep earlier or perhaps take a nap in the afternoon.

A. Alcohol helps you sleep.

B. Here are some things you might have been told about sleeping but aren’t completely true.

C. Everyone should get 7—8 hours of sleep per night.

D. So don’t aim for more sleep — even on the weekends.

E. Waking up in the middle of the night is the pits (烦心事), but it happens to all of us.

F. You’ll have a better day and perhaps sleep better at night.

G. Can you pay that debt back by sleeping on Saturday or Sunday?
