情態副詞

Of the 7 billion people on Earth, roughly 6 billion own a cellphone, which is pretty shocking, given that only 4.5 billion have access to a working toilet.

地球的七十億人口中，大約有六十億人擁有手機，考慮到地球上只有四十五億人有廁所可以使用，卻有六十億人擁有手機，實在很讓人驚訝。

So how are these popular gadgets changing your body and brain?

所以這些大受歡迎的小玩意兒，是如何影響你們的身體和大腦呢？

程度副詞

If you're looking down at your phone right now, your spine angle is equivalent to that of an 8 year old child sitting on your neck - which is fairly significant considering people spend an average of 4.7 hours a day looking at their phone.

如果你此刻正在低頭划手機，你脊椎彎曲的角度已經等同於一個八歲小孩坐在你脖子上。有相當大量的人每天平均花4.7小時看他們的手機。

This, combined with the length of time spent in front of computers has led to an increase in the prevalence of myopia or nearsightedness in North America.

看手機的時間，再加上坐在電腦前的時間，造成在北美地區有越來越多人近視。

In the 1970s, about ¼ of the population had myopia, where today nearly half do; and in some parts of Asia, 80-90% of the population is now nearsighted.

1970年代，大約四分之一的人口有近視，然而現今已經將近一半的人近視了。在一些亞洲地區，總人口數的80-90%近視。

And it can be hard to put your phone down - take for example the game Candy Crush.

並且，你也很難放下你的手機，拿手機遊戲 Candy Crush 來舉例。

As you play the game, you achieve small goals causing your brain to be rewarded with little bursts of dopamine - and eventually you rewarded the game with new content.

當你開始玩遊戲，達成一個小目標會使你的頭腦覺得受到獎勵而分泌多巴胺，這最終會使你得到新的滿足感。

This novelty also gives little bursts of dopamine and together create what is known as a "compulsion loop"

這種新奇的感覺也會促使分泌多巴胺，然後一起製造所謂的「強制循環」

- which just happens to be the same loop responsible for the behaviours associated with nicotine or cocaine.

就像是跟尼古丁或古柯鹼相關的行為所造成的循環一樣。

Our brains are hard-wired to make us novelty seeking, and this is why apps on our phones are designed to constantly provide us with new content, making them hard to put down.

我們的大腦本能地讓我們找新奇的東西，這就是為何我們手機上的那些應用程式不斷提供我們新的滿足感，讓我們很難放下這些應用程式。

As a result, 93% of young people aged 18-29 report using their smartphones as a tool to avoid boredom, as opposed to other activities like reading a book or engaging with people around them.

因此 93% 年齡在18 到 29 歲的年輕人把他們的智慧型手機當成避免無聊的工具，而不是從事其他活動像是讀書，或和周圍的人互動。

This has created the new term "nomophobia" - the fear or anxiety of being without your phone.

因此新詞彙「無手機恐懼症」應運而生，意指沒有手機就感到恐懼或焦慮。

We also see a change in brain patterns: alpha rhythms are commonly associated with "wakeful relaxation" like when your mind wanders off, whereas gamma waves are associated with conscious attentiveness.

我們也看到了大腦的改變：α 節律和人「清醒放鬆」有關連，就像當你在恍神，但你的伽馬波仍跟意識注意力有關。

And experiments have shown that when a cell phone is transmitting - say during a phone call - the power of these alpha waves is significantly boosted,

而且根據研究顯示，當手機在傳送訊號時，α 節律會明顯地增強，

meaning phone transmissions can literally change the way your brain functions.

表示 手機訊號會確實地影響我們大腦的用途。

Your smartphone can also disrupt your sleep! The screen emits a blue light which has been shown to alter our circadian rhythms, diminishing the time spent in deep sleep,

你的智慧型手機也會干擾你的睡眠！手機螢幕發射出的藍光，改變我們的生理時鐘，減少深層睡眠時間，

which is linked to the development of diabetes, cancer and obesity.

這可能導致糖尿病、癌症、肥胖。

Studies have shown that people who read on their smartphone at night have a harder time falling asleep and produce less melatonin - a hormone responsible for the regulation of sleep-wake cycles.

研究顯示在晚上用智慧型手機的人比較難以入眠，並且製造較少的褪黑激素。褪黑激素是掌管規律睡眠的賀爾蒙。

Harvard medical school advises the last 2-3 hours before bed be 'technology' free, so pick up a book before bed instead.

哈佛醫學院建議，睡前 2 到 3 小時不要使用任何科技產品，可以讀個書來代替。

Of course, smartphones also completely change our ability to access information - most notably in poor and minority populations.

當然，智慧型手機也完全改變了我們獲取新知識的能力，特別是窮人跟一些少數族群。

7% of Americans are entirely dependent on smartphones for their access to the internet.

7% 的美國人完全依靠智慧型手機來上網。

A 2014 study found that the majority of smartphone owners use their phone for online banking, to look up medical information and searching for jobs.

一份 2014 年的研究發現，大部份的智慧型手機用戶用手機使用線上銀行、尋找醫療資訊、找工作。

So while phones are in no way exclusively bad, and have been a part of positive change in the world, there's no denying that they are changing us.

手機並不完全只有壞處，而且它也是世界上正向改變的一部份，所以不用否認，智慧型手機正在改變我們。

But, many successful people have now decided to take "smartphone vacations" in order to increase productivity.

但是，為了更高的產值，很多成功人士現在決定放一個「手機假」。
