What If Past Your Bedtime?
Despite increasing awareness of how critical sleep is to our health, getting a good night's rest remains increasingly difficult in a world that's always "on" — responding to emails at all hours, news cycles that change with every tweet and staring endlessly into the blue light of cell phone, tablet and computers screens.
尽管越来越多的人意识到睡眠对我们的健康有多么重要，但在一个永远 “开着” 的世界里，睡个好觉仍然越来越困难——不分昼夜地回复电子邮件，新闻周期随着每条推文而改变，无休止地盯着手机、平板电脑和电脑屏幕发出的蓝光。
Scientists have stressed the importance of healthy sleep habits, recommending at least seven hours each night.
科学家们强调了健康睡眠习惯的重要性，建议每晚至少睡7个小时。
Now a new study shows whether or not you go to bed on time could also have an effect on your health.
现在一项新的研究表明，你是否按时上床睡觉也会对你的健康产生影响。
The study found that even if you get seven hours of sleep a night, if you're not going to bed at the same time each night, not only does your resting heart rate increase while you sleep, it carries over into the next day.
研究发现，即使你每晚有7个小时的睡眠时间，如果你每晚不在同一时间上床睡觉，那么，你睡觉时的静息心率不仅会加快，而且会持续到第二天。
Surprisingly, going to bed earlier than one's standard bedtime also showed signs of increasing RHR, though it depended on just how early.
令人惊讶的是，早于标准睡眠时间上床睡觉也显示出静息心率加快的迹象，尽管这取决于睡眠时间到底有多早。
Going to bed 30 minutes earlier than usual appeared to have little effect, while going to bed more than a half hour earlier significantly increased RHR.
比平时提前30分钟上床睡觉似乎没有什么影响，而如果上床睡觉的时间被提前得超过了30分钟，则显著增加了静息心率。
But it's vital to consider consistency as well.
但是考虑连贯性也是至关重要的。
"For some, it may be a matter of maintaining their regular 'work week' bedtime through the weekend," said Chawla.
Chawla说，“对于一些人来说，这可能是一个把他们规律的 ‘工作周’ 的就寝时间保持到周末的问题” 。
"For shift workers and those who travel frequently, getting to bed at the same time each night is a challenge. Establishing a healthy bedtime routine — as best you can — is obviously step number one. But sticking to it is just as important."
“对于轮班工人和经常出差的人来说，每晚在同一时间上床睡觉是一个挑战。 尽你所能建立一个健康的就寝习惯，这显然是第一步。但坚持下去也同样重要。”
