Study: Humans Sleep Less, Better Than Other Animals
Humans need less sleep than other mammals, yet their slumber is more efficient, said researchers at Duke University in North Carolina.
In their study, the scientists researched sleep patterns of hundreds of animals. They discovered humans sleep for shorter periods of time compared to other animals.
The study also concluded that a human's sleep is higher quality. A deeper stage of sleep, called rapid eye movement sleep, or REM, makes up 25 percent of a human's sleep. In primates like lemurs or monkeys, REM sleep does not reach the five percent mark.
"Humans are unique in having shorter, higher quality sleep," said David Samson, a study co-author.
Samson's research team found that humans can prosper with an average of seven hours of sleep a day. Other primates need as many as 14 to 17 hours of sleep.
Samson said human sleep habits evolved during prehistoric times. Human ancestors moved from sleeping in trees to sleeping on the ground. Better sleeping habits resulted in better sleep in a shorter amount of time.

揭人类睡眠之谜
美国北卡罗来纳州杜克大学的研究人员表示，人类的睡眠比其它的哺乳类动物少的多，然而睡眠质量却高于其他的动物。
研究显示，科学家们对数百种动物进行睡眠规律的测试。最后发现，与其它动物的睡眠时间相比，人类的睡眠时间要少很多。
研究还得出另一个结论：人类的睡眠质量较高。深度睡眠也被称为快速眼动睡眠，占人类睡眠的25%。而狐猴或猴子之类的灵长类，其快速眼动睡眠竟然不及5%。
研究的另一合作者大卫·萨姆森表示，“人类睡眠时间虽短但是睡眠质量却很高，这是人类独有的特点。”
萨姆森的研究团队还发现，人类平均每天睡7个小时就能精神焕发。而其它的动物则需要长达14甚至17个小时。
萨姆森称，在史前时期人类这一睡眠习性开始发生进化。人类祖先先是睡在树上继而睡在地上。良好的睡眠习惯能够让你在短时间的睡眠中拥有较高的睡眠质量。
