Dear colleagues, I am pleased to say that the results of our “Sleep Into The Future” trial are now in. For background, you all know how evangelical(狂热的；福音派的) Stew is about his own sleep routine and the importance of feeling rested. The evidence from other industries is clear about the negative effects of sleep deprivation(睡眠剥夺；睡眠不足). For these reasons, we decided to roll out(推出；正式实施) a series of pilot trials(试点试验) to our team in Canada and to the legal function worldwide, designed to ensure that all our colleagues feel energised and ready to do their best work. I have laid out the main findings below, along with a recommendation on next steps.
亲爱的同事们，我很高兴地宣布，我们的“睡眠进入未来”试验结果已经出炉。作为背景，你们都知道斯图对自己的睡眠习惯有多么狂热，以及他多么看重休息充分的重要性。其他行业的证据清楚地表明，睡眠不足会带来负面影响。基于这些原因，我们决定在加拿大团队和全球法务部门推出一系列试点试验，旨在确保所有同事都精力充沛，准备好全力以赴地工作。下面我列出了主要发现，以及对下一步的建议。
We ran a specific initiative(举措；倡议) called “Waking Hours”, in which volunteers experimented with pre-industrial(前工业时代的) sleep patterns. There is some evidence to suggest that humans used to rise in the middle of the night(半夜起身) after a first sleep, to do whatever it was that people did back then, before having a second sleep. Our volunteers were asked to wake at 2am in order to do work for two hours, before then going back to bed. Some people adjusted to this rhythm; others found it difficult to fall asleep again and entered a state of catatonic(木僵的；僵直症的) exhaustion. At least one big sales lead(销售线索) evaporate(蒸发；消失)d when our salesperson’s second sleep took place in the middle of a client meeting.
我们开展了一项名为“清醒时间”的具体举措，让志愿者体验前工业时代的睡眠模式。有证据表明，人类过去常常在第一觉之后半夜起身，做当时人们会做的各种事情，然后再睡第二觉。我们要求志愿者凌晨两点醒来工作两小时，然后再回去睡觉。有些人适应了这种节奏；另一些人则难以再次入睡，陷入了木僵般的极度疲惫。至少有一个大销售线索泡了汤，因为我们的销售员在客户会议中途进入了第二觉。
There were unexpected ripple effects(连锁反应；涟漪效应). When senior people began sending emails and Slack messages at 3am, more junior team members who were not involved in the trial began waking much earlier in order to respond promptly(及时地；迅速地). In turn, their pre-dawn(黎明前的) activity prompted even more colleagues to start work earlier. Once this cascade(级联；瀑布式倾泻) effect is taken into account, we think that sleep quality in the organisation as a whole declined.
出现了意想不到的连锁反应。当高管们开始在凌晨三点发送邮件和 Slack 消息时，未参与试验的初级团队成员为了及时回复，也开始起得更早。反过来，他们黎明前的活动又促使更多同事提早开工。一旦把这种级联效应考虑在内，我们认为整个组织的睡眠质量都下降了。
