美国国会的一个专没委员会用5年时间研究睡眠和失眠的问题,其结论既出乎意料又可悲可叹:社会每年为睡眠问题付出500亿美元的代价,约4000万美国人长期睡眠不足或失眠。此外,美国几乎所有人睡眠时间不足。
A five-year study of sleep and insomnia in a non-commissioning session of the U.S. Congress ends with an unexpected and sad conclusion: the community spends $ 50 billion a year on sleep problems, about 40 million Americans suffer from chronic sleep deprivation or sleeplessness . In addition, almost all Americans do not have enough time to sleep.
