睡覺時，身邊放手機有危害嗎？

如今，很多人都離不開手機，不僅是低頭看手機，就連晚上睡覺也會把手機放在枕頭旁邊，那么睡覺的時候，如果我們長期把手機放在身邊的話，會不會有危害呢?一起聽聽專家的回答。

來自倫斯勒理工學(xué)院教授Mariana Figueiro的回答：

IT DEPENDS ON THE KIND OF DEVICE and how long people are being exposed to it, but there’s clearly a potential for suppressing melatonin in the evening, which is the hormone we start producing a couple of hours prior to bedtime. Melatonin is essentially a nighttime or darkness signal, telling us it’s time to go to bed. So, if you delay the onset of that signal in the evening, by being exposed to too much light coming from those devices, you may be delaying sleep times. Then, if you have a fixed wake up time and can’t sleep in to compensate, you are experiencing sleep deprivation. Even if you filter the light of the display or somehow protect yourself from it, it may be just as bad, because you’re still depriving yourself of sleep by staying awake to use the device.

這取決于電子設(shè)備的種類和人們使用的時長。但使用電子設(shè)備就極有可能抑制夜間褪黑激素的分泌，褪黑激素是睡前幾小時開始分泌的一種激素，其實是夜間或黑暗的信號，告訴我們到睡覺時間了。所以，如果推遲夜間這一信號的發(fā)出，暴露在這些設(shè)備所發(fā)出的過多光亮之下，可能就是在推遲睡眠時間，而且如果早上起床時間固定還不能補覺的話，你可能會缺覺。即使你將屏幕調(diào)暗，或者以某種方式保護自己不受光的影響，結(jié)果也一樣，因為熬夜使用電子設(shè)備仍然會缺覺。

Sleep deprivation has been linked to a series of things—it’s been shown that after five consecutive days of five hours of sleep instead of eight hours, people can become pre-diabetic or become hungrier. In the short-term, you become sleepier during the day, and you may reduce daytime performance. And then long-term, you may have more serious consequences, such as increased risk for obesity, diabetes, cardiovascular disease, and even increased risks of cancer. I’m not saying that these self-luminous displays cause cancer. But you want to minimize disruption of circadian rhythms and the curtailment of sleep as much as possible.

睡眠不足會有一系列后果——有研究表明連續(xù)五天只睡五小時而睡不夠八小時的話，人會進入糖尿病前期，或更容易餓。短期內(nèi)白天會更困，而且表現(xiàn)欠佳。長期睡眠不足會有更嚴重的后果，比如患肥胖、糖尿病和心血管疾病的風(fēng)險都會增加，甚至患癌癥的風(fēng)險也會增加。我不是說這些發(fā)光的屏幕會致癌，但你也是想盡量減少對身體晝夜規(guī)律的破壞，保證充足睡眠。
