Many problems and frustrations(挫折),
from anger to stress, have become part of the American way of life. They may
result from inadequate sleep and widespread sleep problems according to a study
26 April 2 by the National Sleep
Foundation (NSF).
The study results show that while many Americans enjoy the 27 of sufficient sleep, as many as 47 million
adults may be putting themselves
28 injury, and
health and behaviour problems because they aren’t meeting their 29 sleep need in order to be fully alert (清醒) the
next day. Such people are more likely to get 30 in traffic jams, quarrel with
other people, or overeat, according to the 31 .
“The study provides new evidence that the quality and quantity of
our sleep plays a significant role in our daily lives. In sum. The study
results paint a new and unique 32 of Americans that shows ‘you are 33 you sleep.’” The researchers noted, “Some
of the problems we face may be linked to lack of sleep or poor sleep.”
The study 34 how people described their general moods
and attitudes on a typical day with their answers to a number of questions
about their sleep. The conclusions suggest a direct link between more sleep and
heightened daytime alertness with 35 feelings that include a sense of peace,
satisfaction with life, and being full of energy. Shorter sleep periods and
daytime sleepiness were related to negative moods such as anger, stress,
pessimism (悲观) , and
tiredness.
