英國每日電訊:研究人員稱,對于那些夜里不能睡安慰覺的人來說,比如說新媽媽們或者上夜班的護士,盡管他們每天的睡眠時間足夠,但睡眠的效果相當于他們只睡了四個小時.
The Telegraph: Being woken up regularly during the night can leave parents and on-call workers feeling as sleep deprived as if they had only four hours rest a night.
Researcher discovered that being pulled from a deep slumber by a crying baby or a frantic emergency call, causes the same confusion, depression and fatigue as being severely sleep-deprived.
It means that even when people get a total of seven hours sleep a night, being forced to wake up for regular 15 minute feeds, or consultations, will leave them feeling like they had just four hours rest.
