晚上玩手機(jī)會(huì)發(fā)生什么？看完嚇得我把手機(jī)藏在了床底下

睡覺前，很多小伙伴們都喜歡拿著手機(jī)。刷刷微信，看看微博，玩玩游戲，讓你24小時(shí)都離不開它，甚至還經(jīng)常與它同床共枕!

但是，晚上關(guān)燈玩手機(jī)然后放一邊睡覺的同時(shí)也給我們身體帶來了巨大的隱患!

很多人都有睡覺時(shí)把手機(jī)放在身旁的習(xí)慣。那么這樣做到底有沒有危險(xiǎn)呢?

Whether it’s waiting up for a response to an unanswered text, replying to work emails long after the end of the business day, or aimlessly scrolling through Instagram, even the most disciplined among us can be found at least occasionally—if not regularly—tucked into bed with our smartphones tightly in hand or nestled under our pillows.

不管你是在等著他人回復(fù)一條信息，或者在工作日下班很久后回電郵，又或是在Instagram上漫無目的的刷屏，甚至是最能自律的人們，也有可能偶爾——如果不是經(jīng)常——緊緊的抱著手機(jī)窩在床頭或是躺在枕邊。

In a Gallup survey, 63% of respondents admitted to keeping their smartphones close by while sleeping. But aside from the generalized guilt that comes with procrastinating before bedtime, is it actually dangerous to sleep with your smartphone?

在蓋洛普(Gallup)的一項(xiàng)調(diào)查中，63%的受訪者承認(rèn)他們?cè)谒X時(shí)會(huì)把手機(jī)放在身邊。但是，除了玩手機(jī)拖延了睡眠時(shí)間這種普遍的負(fù)罪感之外，睡覺時(shí)把智能手機(jī)放在身旁到底有沒有危險(xiǎn)?

We turned to several experts in fields like chemistry, sociology, and psychologyto identify and explain the risks associated with sharing your bed with your electronic devices.

我們求助于幾位化學(xué)、社會(huì)學(xué)和心理學(xué)等領(lǐng)域的專家來識(shí)別并解釋你與電子設(shè)備同床共枕的風(fēng)險(xiǎn)。

FOR ELECTRONIC DEVICES LIKE LAPTOPS, phones, anything with a LED or LCD display, the problem is that they produce a large amount of artificial blue light. Our natural cue to what time of day it is, primarily to know when morning is, is blue light. By exposing ourselves to large amounts of blue light late at night, we are giving our bodies a cue that it’s time actually to wake up instead of go to sleep. This can lead to defects in our circadian rhythm, and it’s been shown that when we have our biological clock out of phase with the natural day-night cycle outside, that can lead to increases in the rates of diabetes, cancer, heart disease, and even depression.

對(duì)于任何像筆記本和手機(jī)這樣任何一種帶有LED或LCD屏幕的電子設(shè)備來說，問題就在于它們會(huì)發(fā)出大量人造藍(lán)光。我們自身對(duì)一天中各時(shí)間段的感知就依靠藍(lán)光，主要是知道什么時(shí)候是早上。深夜我們還把自己暴露在大量藍(lán)光下，就是在提示身體該起床了，而不是該睡覺了。這會(huì)導(dǎo)致我們晝夜規(guī)律的混亂，而且有研究表明生物鐘與外界自然的晝夜循環(huán)不一致時(shí)，糖尿病、癌癥、心臟病、甚至抑郁的發(fā)病率都會(huì)上升。

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(shí)長(zhǎng)。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(shí)開始分泌的一種激素，其實(shí)是夜間或黑暗的信號(hào)，告訴我們到睡覺時(shí)間了。所以，如果推遲夜間這一信號(hào)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(shí)間，而且如果早上起床時(shí)間固定還不能補(bǔ)覺的話，你可能會(huì)缺覺。即使你將屏幕調(diào)暗，或者以某種方式保護(hù)自己不受光的影響，結(jié)果也一樣，因?yàn)榘疽故褂秒娮釉O(shè)備仍然會(huì)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—that would be a big statement. But you want to minimize disruption of circadian rhythms and the curtailment of sleep as much as possible.

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

SLEEPING WITH THESE TYPES OF DEVICES IS NOT TOO WISE, primarily because of their association with disrupted sleep. From TVs to computers to tablets and smartphones, young children’s sleep seems to be very compromised. Whether these devices disrupt sleep because of noise, light, social interactions (or the promise of them), such devices take a toll. The downsides of insufficient and disrupted sleep are many, including learning and memory deficits, cognitive impairment, metabolic difficulties, depressed mood, disrupted immune function, and excessive fatigue—to name a few.

將這些設(shè)備放在身旁睡覺并不明智，主要是因?yàn)樗鼈儠?huì)導(dǎo)致睡眠中斷。從電視到電腦到平板再到手機(jī)，孩子們的睡眠似乎受到了很大的影響。不管睡眠中斷是因?yàn)樵胍簟⒐饩€、社交活動(dòng)(或是他們給人的一種期待)，這都是這些設(shè)備所造成的。舉例來說，睡眠不足和睡眠中斷的不利因素包括學(xué)習(xí)和記憶障礙、認(rèn)知障礙、代謝困難、情緒低落、免疫功能紊亂和過度疲勞等等。

此外，手機(jī)的電磁輻射對(duì)人體頭部危害較大，它可能會(huì)對(duì)人的中樞神經(jīng)系統(tǒng)造成影響，引起頭痛、頭昏、失眠、多夢(mèng)和脫發(fā)等癥狀，還會(huì)影響深睡眠，降低睡眠質(zhì)量。

手機(jī)在待機(jī)和接通兩種不同情況下輻射值不一樣，并且距離手機(jī)越遠(yuǎn)，電磁輻射值越小。

夜里躺在床上玩手機(jī)也會(huì)對(duì)眼睛帶來隱形傷害，久而久之，視力越來越差、眼睛也會(huì)很容易痛，甚至還會(huì)經(jīng)常性頭痛……

愛自己，晚上請(qǐng)遠(yuǎn)離手機(jī)!更不要在晚上睡覺的時(shí)候給手機(jī)充電!這樣不確定性的因素更大!如果不得不把手機(jī)放在床頭，請(qǐng)務(wù)必關(guān)機(jī)!
