• 12．Let's do some sleep math.You lost two hours of sleep every night last week because of a big project due on Friday.On Saturday and Sunday，you slept in，getting four extra hours.On Monday morning，you were feeling so bright-eyed，and you only had one cup of coffee，instead of your usual two.But don't be cheated by your energy：You're still carrying around a heavy load of sleepiness，or what experts call "sleep debt" -in this case something like six hours，almost a full night's sleep.
     Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get.It's a deficit （赤字）that grows every time we skim some extra minutes off our nightly sleep."People accumulate（积累）sleep debt gradually without being noticed，" says psychiatrist William C.Dement，the founder of the Stanford University Sleep Research Centre.Studies show that such short-term lack of sleep leads to a foggy brain，worsened vision，and trouble remembering.Long-term effects include obesity and heart disease.A survey by the National Sleep Foundation reports that we're losing one hour of sleep each night-more than two full weeks of sleep each year.
     The good news is that，like all debts，with some work，sleep debt can be repaid.Adding an extra hour or two of sleep a night is the way to catch up on sleep debt.For the long-term lack of sleep，take it easy for a few months to get back into a natural sleep pattern.Go to bed when you are tired，and allow your body to wake you in the morning （no alarm clock allowed）.You may find yourself catatonic （有紧张感的）in the beginning of the recovery cycle：Expect to have ten hours' shut-eye per night.As the days pass，however，the amount of sleeping time will gradually increase.
     So earn back that lost sleep-and follow the orders of your inner sleep needs，and you'll feel better. "When you put away sleep debt，you become superman，" says Stanford's Dement，talking about the improved mental and physical abilities that come with being well rested.

• 13．Children should spend at least one hour playing and spending time in nature each day，according to the Wildlife Trusts （野生生物基金会）.The UK organization speaks for 46 groups and 2，300 nature protection areas. （1）

     However，parents on their own aren't giving kids that time.（5）
