1
Of the 7 billion people on Earth, roughly 6 billion own a cell phone, which is pretty shocking given that only 4.5 billion have access to a working toilet.
2
So how are these popular gadgets changing your body and brain?
3
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,
4
which is fairly significant considering people spend an average of 4.7 hours a day looking at their phone.
5
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.
6
In the 1970s, about one quarter of the population had myopia, where today nearly half do, and in some parts of Asia,
7
80-90% of the population is now nearsighted.
8
And it can be hard to put your phone down.
9
Take for example the game Candy Crush.
10
As you play the game, you achieve small goals, causing your brain to be rewarded with little bursts of dopamine.
11
and eventually you're rewarded in the game with new content.
12
This novelty also gives little bursts of dopamine and together create what is known as a compulsion loop,
13
which just happens to be the same loop responsible for the behaviors associated with nicotine or cocaine.
14
Our brains are hardwired 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.
15
As a result, 93% of young people aged 18-29 report using their smartphone as a tool to avoid boredom,
16
as opposed to other activities like reading a book or engaging with people around them.
17
This has created a new term, gnomophobia, the fear or anxiety of being without your phone.
18
We also see a change in brain patterns.
19
Alpha rhythms are commonly associated with wakeful relaxation, like when your mind wanders off, whereas gamma waves are associated with conscious attentiveness.
20
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,
21
meaning phone transmissions can literally change the way your brain functions.
22
Your smartphone can also disrupt your sleep.
23
The screen emits a blue light which has been shown to alter our circadian rhythms, diminishing the time spent in deep sleep, which is linked to the development of diabetes, cancer and obesity.
24
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.
25
Harvard Medical School advises the last 2-3 hours before bed be technology free, so pick up a book before bed instead.
26
Of course, smartphones also completely change our ability to access information, most notably in poor and minority populations.
27
7% of Americans are entirely dependent on smartphones for their access to the internet.
28
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.
29
So while phones are in no way exclusively bad, and have been part of a positive change in the world, there's no denying that they are changing us.
30
But many successful people have now decided to take smartphone vacations in order to increase productivity.
31
In our new ASAP Thought video, we break down the top 6 reasons you should take a smartphone vacation and how it could benefit your life right now.

Objetivos de fala para este clipe

Este vídeo é ideal para praticar a fluência em contextos analíticos, especialmente ao descrever impactos científicos e sociais. Ele ajuda a organizar ideias complexas em frases claras, um marco essencial para conversações informativas em inglês. Além disso, o ritmo moderado e a variedade de vocabulário técnico (mas acessível) permitem treinar a compreensão auditiva e a produção oral simultaneamente, ótimo para quem quer melhorar o shadowing em inglês.

Banco de frases reutilizáveis

  • "which is pretty shocking given that..." (o que é bastante surpreendente, considerando que...)
  • "this, combined with..." (isso, combinado com...)
  • "has led to an increase in the prevalence of..." (levou a um aumento na prevalência de...)
  • "it can be hard to put your phone down" (pode ser difícil deixar o celular de lado)
  • "our brains are hardwired to..." (nossos cérebros estão programados para...)
  • "there's no denying that..." (não se pode negar que...)

Corrija seus pontos fracos

O vídeo ajuda a melhorar a pronúncia de palavras com estresse variado, como "prevalence" (pré-va-lêns) e "circadian" (sir-câ-dian), além de treinar a ritmo nas frases longas. Muitas expressões usam "which" e "whereas" para conectar ideias, o que é crucial para a fluência. Praticar o shadowing com essas frases ajuda a internalizar a estrutura de orações complexas. Além disso, o vocabulário técnico (como "myopia", "dopamine") é pronunciado claramente, facilitando a aprendizagem de termos específicos. Para quem quer aprender inglês com vídeos, este clipe é perfeito: combine a visualização com o shadowing site para fixar os sons e a estrutura.

Lembre-se: a chave é repetir frases lentamente, imitando o tom e o ritmo do narrador. Isso não só melhora a pronúncia, mas também a confiança na conversação em inglês.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
