文字稿

Young people today grow up surrounded by digital entertainment and information on multiple screens, whether via computer, smartphone or television.

如今的年輕人在多屏數(shù)字娛樂和信息的包圍下成長，無論是通過電腦、智能手機還是電視機。

In its guidance to parents, the Royal College says the popular view that time in front of a screen is toxic to health has essentially no evidence to support it.

英國皇家兒科和兒童健康學院在給家長的指導意見中表示，長時間坐在屏幕前有害兒童健康的觀點從根本上來講是沒有證據(jù)支持的。

Professor Russell Viner, President, Royal College of Paediatrics and Child Health
Many things are harmful to us. Crossing the road is harmful. Even reading, which we think of as a really important thing, actually is a bit of a sedentary occupation that can keep you up at night. So we think that there's a balance to be struck. There are harms from screens. But actually, screens bring us great opportunities and we have to balance those.

羅素·瓦伊納教授 英國皇家兒科和兒童健康學院院長
“很多事情都對我們有害。過馬路就很危險。就連看書這件大家認為很重要的事，其實都算是久坐不起的活動，有可能讓你夜不能寐。所以我們認為有必要找到一個平衡點?？雌聊皇怯泻μ?，但它其實也給我們帶來了巨大的機遇，我們必須權(quán)衡利弊。”

The guidance says parents with healthy, active children should not worry greatly about computer and smartphone use, although it recommends no screens for an hour before bed, in part because the light can slow the release of the sleep-inducing hormone melatonin.

這份指南說，如果孩子健康、活躍、好動，那么家長不必過多擔心電腦和智能手機的使用，不過指南建議在睡前一小時不要看屏幕，部分原因是光線會減緩促進睡眠的褪黑激素的釋放。

The Royal College says families should negotiate screen time limits with their children, based on individual needs and how much they impact on sleep, physical and social activities.

英國皇家兒科和兒童健康學院表示，家長應和孩子就看屏幕的時間限制進行溝通，并根據(jù)個人需要以及屏幕對睡眠、身體和社交活動的影響程度來決定。
