随着生活节奏的加快,人们的睡眠时间越来越受到挤占。美国华盛顿州立大学睡眠和绩效研究中心主任格雷格·布兰克利博士说:“减少睡眠时间,会降低工作效率,出现其他问题的风险也加大了。”在美国,每年大约有4000万人存在睡眠紊乱的问题,晚上无法获得充足的休息。托马斯·爱迪生1880年发明灯泡以前,人们平均每晚睡10个小时。根据美国国家睡眠基金会的最新统计,美国人平时的平均睡眠时间是6.9小时,周末的平均睡眠时间是7.5小时。
As the pace of life accelerates, people’s sleep time is more and more squeezed. Dr. Greg Blanchell, director of the Sleep and Performance Research Center at Washington State University in the United States, said: “Reducing sleep time will reduce productivity and increase the risk of other problems.” In the United States, about 40 million People have problems sleeping disorders, not enough rest at night. Before Thomas Epson invented the bulb in 1880, people sleep an average of 10 hours per night.
