One
sheep, two sheep，632 sheep…still awake.
People
always believe that counting sheep {#blank#}1{#/blank#}(be)
helpful to their sleep. But does it {#blank#}2{#/blank#}(real)
work?
Scientists
at Oxford University tested it. Two sleep researchers looked at the people who
had {#blank#}3{#/blank#}(difficult) in sleeping. They
divided them {#blank#}4{#/blank#}different
groups. Then they asked them to try all kinds of ways to help {#blank#}5{#/blank#}(they) fall asleep quickly.
Surprisingly,
it {#blank#}6{#/blank#}(take) those who were asked to
count sheep more time to fall asleep than those who weren't. But when they were
asked to imagine a relaxing picture-- a beach, for e {#blank#}7{#/blank#}, they fell asleep about twenty
minutes{#blank#}8{#/blank#}(soon) than before, according
to a report in The New York Times.
“Sometimes,
counting tasks are OK, b {#blank#}9{#/blank#}they
are thought as stressful by many people,” Dr. Richards told ABC News.
“As {#blank#}10{#/blank#}result, it may be a good way to
try imagining colored fish slowly swimming in a river to help you sleep at
night,” suggested Richards.
