最近进行的研究显示,连续数天睡眠不足(每天少于6小时),会对人的智力造成损害。该研究将48名志愿者分成4组,每天分别睡眠4小时、6小时、8小时,持续两周,还有一组志愿者连续3天无睡眠。4组志愿者被分别检测确保他们不会打盹或使用咖啡因。他们每天会规律地接受生理和心理测试,并对其疲劳程度进行评估。 Recent studies have shown that lack of sleep for several days (less than 6 hours a day) can damage people’s intelligence. The study divided 48 volunteers into 4 groups, sleeping 4 hours, 6 hours, 8 hours per day for two weeks, while another group of volunteers did not sleep for 3 consecutive days. Four groups of volunteers were tested individually to ensure they did not nap or use caffeine. They routinely undergo physical and psychological tests on a daily basis and assess their degree of fatigue.
