Many of us wake up (feel) tired in the morning. Many of us ignore the problem as the day goes on, forgetting that it might have a dangerous effect. Society even glorifies “burning the candle at both ends” as a sign of our (devote) to work and family.
Believe or not, all this bad sleep has far-reaching consequences. We do not give ourselves enough chances to sleep. A survey of over 74,000 people found that 35% reported sleeping less than seven hours daily average. Furthermore, the quantity of sleep we allow ourselves (change) greatly over the past 15 years.
This lack of sleep can lead to many serious (problem). One study found that (simple) limiting yourself to six hours of sleep a night for two weeks made performance on a timed attention task as poor as if you (stay) up all the night before.
If you intend to try extending your sleep period, consider giving yourself a chance (sleep) longer for a full week. Your body clock might be programmed in a way keeps you from falling asleep quickly, but it might let you sleep longer.
