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?
2
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.

이 비디오는 누구를 위한 것인가?
영어 회화 연습을 하며 일상적인 주제로 과학 지식도 쌓고 싶은 중급 이상 학습자에게 적합합니다. 특히 IELTS 스피킹 준비생은 논리적 설명과 다양한 예시를 다루는 이 비디오를 통해 말하기 실력을 키울 수 있습니다. 유튜브 영어 공부를 하며 shadow speak 기술을 연마하고 싶다면, 명료한 발음과 자연스러운 흐름이 돋보이는 이 대화가 좋은 연습 소재가 될 것입니다.
빼놓을 수 없는 단어와 관용구
- correlation: 상관관계. "The correlation between cold weather and sickness"에서 '추운 날씨와 질병의 상관관계'로 사용되었습니다.
- pathogens: 병원균. "exposure opportunities for the pathogens"는 '병원균에 노출될 기회'를 뜻합니다.
- constriction: 수축. "blood vessel constriction"은 '혈관 수축'입니다.
- compromised: 약화된. "its spreading ability is compromised"는 '전파 능력이 약화된다'는 뜻입니다.
어떻게 발음을 제대로 익힐까?
이 비디오의 화자는 명확한 발음과 일정한 속도를 유지하며 설명합니다. 특히 cortisol (코티솔)이나 envelope (외피)와 같은 어려운 단어도 부드럽게 발음하므로, shadow speak 시에는 음절을 분리하지 말고 자연스럽게 따라하는 것이 중요합니다. 또한, "Not so fast!"나 "as simple as that"과 같은 구체적인 표현은 강세와 억양을 살려 연습해야 합니다. 이를 통해 영어 회화에서 자연스러운 반응을 할 수 있는 능력을 키울 수 있습니다.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
