纽约城市大学的研究者们发现，小睡一觉能提高人的记忆力。
Volunteers were told to memorise pairs of words. When they were tested straight afterwards and six hours later, those who had been allowed a nap of up to one hour before the retest achieved 15 percent higher scores than the volunteers who had not been allowed to go to sleep.
研究人员让参加调查的志愿者记住几组单词，并在分别记完之后和6小时后对他们进行测试。结果发现，那些在接受再次测试前小睡了1小时的人比未小睡的人得分高出15个百分点。
