20. Sleep is a physical and mental (精神的) need. We all need to sleep, though the sleep hours are different from person to person. Doctors do not know why we need sleep, but they all agree that sleep is very important to us. Without enough sleep, the body may be weak.
One third of adults have sleeplessness. There are over 80 kinds of sleep-related disorders (失调). However, other adults are lucky and have no sleeping problems. They sleep as soon as their heads hit the pillows. Do you sleep well?If you have sleeplessness, here are a few suggestions.
①Make a timetable, and stick to it.
We need to sleep at regular times. If your bedtime and wake-up time change from day to day or on weekends, your sleep rhythms (节奏) aren't predicted and the body doesn't know how to act. So it's important to have a regular wake-up time, even on weekends, vacations or after a night of poor sleep.
②Don't lie in bed awake.
"The best sleep tip you can give somebody is to get up — don't lie in bed awake," sleep expert Grandner said. "Whether it's the beginning of the night or the middle of the night, if you've been awake for 20 or 30 minutes, get up and reset (重新调整). Maybe you just need five minutes to get sleepy, or maybe an hour, but don't spend that time awake in bed."
③Change your thinking about sleep.
"Many people regard sleeping as the final thing they have to do for daily activities. They would like to work or watch TV very late rather than sleep on time. That thinking needs to be changed." Grandner said.
"Don't see your sleep as the time you have left in your day," he advised. "See your sleep as the time you need in order to prepare yourself for an energetic (精力充沛的) tomorrow."
"It may sound like a small change in thinking, but it's an important one." Grandner added.
