Winter is coming - and we've all been told to put on a jacket outside, or you'll catch a cold! Of course, the common response of today has become 'Don't be silly, being cold can't give you a cold'. Or can it? Who wins in this battle of the beliefs?

The correlation between cold weather and sickness does stand out. Between 5-20% of Americans catch a cold or flu every year around late fall and winter. Not to mention, it's called a cold. But there are some important things to consider. First and foremost: colds and the flu are caused by viruses. if there aren't any around, you won't catch a cold - no matter how cold you get. It's as simple as that.
3
So why the correlation with decreasing temperatures? Well for one, people tend to stay indoors much more often during the winter, which in turn, puts them in contact with more people.
4
More people, means more exposure opportunities for the pathogens to spread. On top of this, humidity plays a role in the spread of some viruses. As the humidity decreases in the winter, not only does the virus spread more readily, but the mucus in your nose dries out. Mucus would otherwise act as a protective barrier to pathogens. Finnaly, the lack of Vitamin D which we get from the sun, can affect our immune system adversely.
5
Both being inside more often, and the fact that winter has shorter days makes this a big factor for your health.
6
So you've proven your parents wrong... right? Not so fast!
7
While some past studies have shown no correlation to temperature, recent evidence suggest otherwise.
8
One study which put test subjects feet into ice water found that they were, indeed, more likely to develop common cold symptoms in the following days, than those who didn't.
9
The developing hypothesis behind these results is that the cold temperatures cause blood vessel constriction, which slows the white blood cells from reaching the virus, ultimately inhibiting the immune response. Cortisol levels, which pressures the immune system, are also increased with temperature induced stress. Furthermore, studies on both mice and human airway cells found that immune reaction to the common cold virus, in fact, temperature dependent. Warm infected cells are more likely to undergo programmed cell death, to limit the spread of infection.
10
Finally, studies of the virus itself have revealed a secret weapon of sorts. In winter temperature, the virus's outer layer or envelope becomes much harder and acts like a shield.
11
This allows it to spread from person to person much more easily. But at warm temperatures, this layer is more of a gel, which is not quite tough enough to protect the virus against the elements. As a result, its spreading ability is compromised.
12
So, maybe your parents weren't so wrong after all. A happy compromise of going outside more often, bundled up, is likely to get you through the winter unscathed.

Objetivos de fala para este vídeo

Este vídeo é perfeito para quem quer aprimorar a prática de conversação em inglês com temas cotidianos e científicos. Ele ajuda a alcançar o marco de fluência de entender e reproduzir explicações complexas de forma clara, usando conectivos e vocabulário técnico de forma natural. Ideal para quem quer dominar a arte de falar sobre assuntos científicos de forma acessível, um skill super útil em debates ou apresentações.

Banco de frases reutilizáveis

  • "The correlation between... does stand out" (A correlação entre... é evidente)
  • "On top of this..." (Além disso...)
  • "The developing hypothesis behind these results is that..." (A hipótese em desenvolvimento por trás desses resultados é que...)
  • "A happy compromise of..." (Um bom equilíbrio entre...)
  • "Get you through the winter unscathed" (Te ajudar a passar o inverno ileso)

Essas frases são ótimas para shadowing em inglês, pois combinam estrutura gramatical com expressões coloquiais. Pratique repetindo elas em voz alta, imitando o ritmo e a entonação do narrador!

Corrija seus pontos fracos

O vídeo é excelente para trabalhar a pronúncia de palavras com consoantes difíceis (como "pathogens", "constriction" ou "envelope") e a ritmo das frases longas. Muitas vezes, ao falar inglês, a gente acelera ou desacelera demais, perdendo a clareza. Use o método de shadowing: reproduza a fala do narrador imediatamente após ouvi-la, focando em manter o mesmo fluxo. Isso ajuda a treinar o ouvido e a articulação ao mesmo tempo. Se precisar de um shadowing site para auxiliar, existem plataformas que permitem pausar e repetir trechos, mas até mesmo o YouTube tem ferramentas de reprodução lenta para facilitar.

Aprender inglês com YouTube nunca foi tão prático! Este vídeo é uma oportunidade perfeita para combinar aprendizado de ciência com aprimoramento da fala. Lembre-se: a chave é a prática constante. Use as frases do banco, trabalhe o shadowing e veja como sua fluência melhora. Você está no caminho certo!

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.
