手機影響睡眠 睡前別玩手機！

More than nine out of 10 young people expose themselves to the blue light from smartphones and tablets， before bed， causing problems with sleep.

90%的年輕人睡前都有玩智能手機或平板電腦的習慣，這其實會影響你的睡眠。

A new survey also shows more than 28m people in the UK regularly get no more than seven hours sleep a night.

一項新的研究發(fā)現(xiàn)，英國約2800萬人睡眠不足7小時。

Prof Richard Wiseman， who commissioned the YouGov poll described the findings as “extremely worrying”.

英國著名的大眾心理學教授理查德·懷斯曼是這次調查的發(fā)起人，他形容這次的結果發(fā)現(xiàn)“非常令人揪心”。

Of the 2，149 adults questioned， 78% said they used electronic devices before going to bed. This rose to 91% among the 18 to 24-year-olds questioned in the survey.

在被調查的2149位成人中，78%表示他們睡前會使用電子設備。其中18-24歲的調查者中睡前玩手機的人數(shù)飆升到91%。

Getting less than seven hours sleep a night is below the recommended guidelines， and is associated with a range of problems， including an increased risk of weight gain， heart attacks， diabetes and cancer.

睡眠不足7小時低于正常值，會帶來一系列的健康問題，包括體重增加、心臟病、糖尿病以及癌癥。

“The blue light from these devices suppresses the production of the sleep-inducing hormone melatonin， so its important to avoid them before bed time，” said Prof Richard Wiseman， from the University of Hertfordshire.

Everyone needs different amounts of sleep， but adults are generally thought to require a minimum of seven to eight hours a night. Teenagers are recommended to get more， about nine hours.

每個人都需要不同時間量的睡眠，但成人一般而言最少需要七到八小時。青少年最好睡得再多點，大概九小時的樣子。

The proportion of people thought to be getting too little sleep had risen by a fifth since a “bedroom poll” conducted last year by the National Sleep Foundation.

而相比去年國際睡眠協(xié)會的“睡前調研”來說，睡眠嚴重不足的人數(shù)已經明顯漲到20%。
