低頭族易患“短信脖”

你是否每天手機不離手——發微信、看小說、玩游戲？如果是的話，要當心“短信脖”。

As we tap away for extended periods of texting, browsing and tweeting, we could be putting ourselves at risk of getting text neck.
長時間發短信、瀏覽網頁和發微博，我們可能患上“短信脖”。

A newly coined condition – text neck – reveals that slumping over your mobile phone, tablets or other hand-held device for hours on end heaps so much pressure on your spine, that we're giving ourselves long-lasting back problems.
“短信脖”是個新造的詞，指一個人連續幾小時低頭看手機、平板電腦等手持設備，導致施加給脊椎的壓力不斷累積，最終給背部造成永久性傷害。

The root of the problem appears to be our heads which, weighing in at 4–5 kilos, are harder to support when we bend over – a little like carrying a weight at arm's length rather than closer to the body.
產生這一問題的根本原因在于我們的頭部：它們重達4至5千克。我們低頭時，就會很難支撐頭的重量——這種情況有點兒類似用胳膊拿重物，離身體越遠就會顯得越重。

Example:
Text neck can lead to wear-and-tear on the spine.
“短信脖”會磨損脊椎。
