Why your phone's 'night mode' may be keeping you awake
你之所以知道手机有一个功能称之为“夜间模式”，只是因为手机一直在提醒。有时当你晚上躺在床上发消息时，你的屏幕口可能会礼貌地建议你激活一项功能，将屏幕的颜色冷光调制暖光。此举是为了帮助你睡得更好。
'Night mode' is one of those features you may be aware of only because your phone keeps telling you about it.At some point while you are lying in bed at night sending texts. Your screen may politely suggest you activate a function that shifts the colors of your screen from the colder to the warmer end of the spectrum.It is supposed to help you sleep better.
由蒂姆·布朗博士发起的一项研究发现表明，这与正确的情况恰恰相反。这项在老鼠身上开展的研究，似乎把蓝光会干扰睡眠的观点贬得一文不值。即在所有条件都相同的情况下，温暖的黄光更糟糕。
Finding in a study led by Dr.Tim Brown suggest this is the very opposite of correct.The research,carried out on mice,appears to rubbish the notion that blue light disrupts sleep.All things being aqual,warm yellow light is worse.
根据这项研究，在刺激人体生物钟方面，亮度水平比颜色更重要。然而，当光线同样暗淡时，蓝色比黄色更让人放松。这符合常理:日光是黄色的，暮光是蓝色的，日出和日落是非常可靠的方式来告诉你的生物钟现在所处的时间。当然，在这一点上，我们只知道这对老鼠是有效的，而老鼠并没有手机。布朗博士说:“我们认为有充分的理由相信人类也是如此。”。
According to the study,brightness levels are more important than color when it comes to stimulating the body clock.However,when the light is equally dim,blue is more relaxing than yellow.This makes basic sense:daylight is yellow,twilight is blue,and sunrise and sunset are pretty reliable ways to tell your body clock what time it is.Of course,at this point,we only know it works on mice - and mice don't have phones."We think there is good reason to believe it/s also true in humans" says Dr.Brown.
或许还有一个更明显的事实需要说明--如果你的手机一直在提醒你需要切换到夜间模式，那就是放下手机的时候了。让你保持清醒的不是屏幕的颜色;正是你的手机所提供的所有东西，让你可以在凌晨2点还不睡觉。真正的夜间模式按钮只有一个:关机按钮。
There is perhaps a more obvious truth to be drawn - if your phone is telling you to switch to night mode,it is time to put down your phone.It is not the color of the screen that is keeping you awake;it is all the stuff your phone offers as an alternative to sleep at 2am.There is only one real night-mode switch:the off button.
