你的手机如何改变你?

How Is Your Phone Changing You?

世界上七十亿人口中
Of the 7 billion people on Earth,
大约有六十亿人拥有手机
roughly 6 billion own a cellphone, which is pretty
相比只有四十五亿人可以使用厕所足以令人震惊
shocking, given that only 4.5 billion have access to a working toilet.
这些备受欢迎的小工具是如何改变你的身体和大脑的呢?
So how are these popular gadgets changing your body and brain?
如果你现在正低头看手机
If you ’ re looking down at your phone right now,
你的脊柱弯曲程度就和
your spine angle is equivalent to that
脖子上坐着个八岁的孩子一样
of an 8 year old child sitting on your neck –
考虑到人们每天花费4.7个小时看手机
which is fairly significant considering people spend an average of 4.7 hours a day
这一结果非常严重
looking at their phone.
再加上
This, combined with
坐在电脑前的时间
the length of time spent
这就导致北美地区
in front of computers has led to an increase in the prevalence of
近视现象越来越普遍
myopia or nearsightedness in North America.
七十年代 近视人群只占四分之一
In the 1970s about ¼ of the population had
而今已经接近一半
myopia, where today nearly half do;
亚洲一些地区 近视率甚至达到
and in some parts of Asia, 80-90 % of the population
80%-90%
is now nearsighted.
放下手机确实很难
And it can be hard to put your phone down –
就拿糖果粉碎游戏为例
take for example the game Candy Crush.
玩游戏时
As you play the game,
完成小目标 大脑会产生多巴胺激励
you achieve small goals causing your brain to be rewarded with little
然后游戏又奖励你新的道具
bursts of dopamine – and eventually you are rewarded with new content.
这种新花样
This novelty also
也会让你的大脑分泌多巴胺 使你最终陷入
gives little bursts of dopamine and together create what is known
“强迫循环”
as a ‘ compulsion loop ’
这种情况和尼古丁或者
– which just happens to be the same loop responsible
可卡因造成的效果一样
for the behaviors associated with nicotine
大脑本身喜欢寻求新颖
or cocaine. Our brains are hard-wired to make us novelty seeking,
手机里各种软件
and this is why apps on
总是提供新内容 就是这原因
our phones are designed to constantly provide us with new content,
这让我们很难卸载
making them hard to put down.
结果
As a result,
18-29岁的年轻人中有93%的人
93 % of young people aged 18-29 report using their smartphones as a tool to
是玩手机打发无聊 而不是
avoid boredom, as opposed to other activities such
读书或者和周围朋友互动
as reading books or engaging with people around them.
因而出现一个新词汇“nomophobia”
This has created the new term ‘ nomophobia ’ –
指因没有手机
the fear or anxiety of
而感到害怕或焦虑
being without your phone.
我们的大脑也发生了变化
We also see a change in brain patterns:
阿尔法节奏通常是“清醒放松”
alpha rhythms are commonly associated with ‘ wakeful
就像思绪飘走一样
relaxation ’ like when your mind wanders off,
而伽马波则和有意识的紧张
whereas gamma waves are associated with
有关 实验发现
conscious attentiveness. And experiments have shown
拨打电话时
that when a cell phone is transmitting
也就是在电话中
– say during a phone call –
阿尔法波就很活跃
the power of these alpha waves is significantly boosted, meaning
说明打电话会改变大脑工作方式
phone transmissions can literally change theway your brain functions.
手机也会影响睡眠
Your smartphone can also disrupt your sleep!
手机屏幕发射的蓝光
The screen emits a blue light which has been
会改变昼夜节律
shown to alter our circadian rhythms,
减少深度睡眠的时间
diminishing the time spent in deep sleep, which is linked
这就跟糖尿病 癌症 肥胖有关
to the development of diabetes, cancer andobesity.
研究表明 在夜间
Studies have shown that people who
使用手机阅读的人
read on their smartphone
更难以入眠 产生更少褪黑素
at night have a harder time falling asleep and produce less melatonin
——一种负责调节睡眠 – 觉醒周期的激素
– a hormone responsible for the regulationof sleep-wake cycles.
哈佛医学院
Harvard medical school
建议入睡前2-3小时不用电子产品
advises the last 2-3 hours before bed be ‘ technology ’ free,
而是读纸质书
so pick up a book before bed instead.
当然 手机完全改变我们获取信息的能力
Of course, smartphones also completely change our ability to access information –
特别是对于穷人和少数民族
most notably in poor and minority populations.
7%的美国人完全依赖手机
7% of Americansare entirely dependent on smartphones for
访问互联网
their access to the internet.
2014年的一项研究发现 大多数人用手机
A 2014 studyfound that the majority of smartphone owners
进行网上银行业务
use their phone for online banking,
查看医疗信息和招聘信息
to look up medical information and searching for jobs.
虽然手机绝不是坏事
So while phones are in no way exclusively bad,
也对世界有积极影响
and have been a part of positive change
但毫无疑问它正在改变我们
in the world, there’s no denying that theyare changing us.
但越来越多成功人士
But, many successful people have now decided
给手机放假

以提高生产力
