最新研究表明 電子設備確實影響青少年的睡眠大綱

A major scientific review has found that simply having an electronic gadget in the room leaves children 'switched on'.

一項重要的科學研究發現，只要孩子們的房間裏放有電子產品，他們隱形的生物鐘就一直得不到休息。

Youngsters are restless because they anticipate receiving texts and social media messages from friends, which affects their night-time routine even if parents impose rules about 'screen time'.

青少年們一直都處在睡眠不足的狀態下，因爲他們無視父母們規定的玩手機或者電腦的時間，在該休息時仍在和朋友們聊天、活躍在各大消息圈和社交媒體網絡上。

The review found that children and teenagers who use an electronic device within 90 minutes of going to bed are twice as likely to get insufficient sleep – and nearly three times as likely to feel sleepy during the day.

這項研究表明，在睡前90分鐘還在玩手機或者電腦等電子設備的孩子或者是青少年，睡眠不足的機率比一般的孩子要大2倍，白天打瞌睡的機率更是幾乎高達3倍。

Experts from King's College London and Cardiff University found that access to media devices at night, even without use, put children at 79 per cent increased risk of getting insufficient sleep, 46 per cent increased risk of poor quality sleep, and 127 per cent increased risk of daytime drowsiness.

來自倫敦大學國王學院和卡蒂夫大學的專家發現，孩子們晚上接觸這些媒體產品，即使是不使用，也會增加79%的造成睡眠不足的可能，46%低質量睡眠的可能以及127%白天打瞌睡精神不振的可能。

Dr Ben Carter, who led the review, said having access to social media at all hours meant children were 'always alert'.

這項調查的發起者本·卡特博士告訴我們，如果孩子一整天都跟這些社交媒體綁在一起，那說明他的身體一直都處於警覺狀態，得不到放鬆。

'If the first thing you do in the morning is check your phone and the last thing you do at night is check your phone, that is indicative of addiction behaviour,' Dr Carter said.

卡特博士說：“如果你每天早晨起牀的第一件事就是看手機，睡前的最後一件事也是看手機，那就說明你已經處於着迷狀態了。”

Dr Carter, who stressed that his theory had not been proven, added: 'If you send a message an hour before you go to bed, you are still switched on when you try to sleep, in case there is a reply.'

卡特博士強調他的理論還沒有被證實過，並說：“如果你睡覺前發了一條消息，那當你睡覺的時候肯定大腦還在運轉，以免擔心錯過了別人的回覆。”

Separate research suggests that 72 per cent of children and 89 per cent of adolescents have at least one device in their bedrooms and most are used near bedtime.

其他獨立的研究表明，72%的孩子和89%的青少年在他們的房間裏至少有一項電子設備，而且大部分都是睡前使用。

Dr Carter's team, whose work is published in the JAMA Pediatrics journal, reviewed 20 existing studies from four continents, involving more than 125,000 children aged between six and 19.

卡特博士研究團隊的工作成果已經在《美國醫學會期刊》兒科分刊上發表了，綜述了來自四大洲的20個現有研究，其研究對象是年齡在6到19歲的約12.5萬名兒童。

He said: 'Our study provides further proof of the detrimental effect of media devices on both sleep duration and quality.'

他表示：“我們的研究爲證實社交媒體對睡眠時間和睡眠質量的有害影響提供了進一步的證據。”
