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.

What You'll Learn

This video is a goldmine for english speaking practice, helping you build two key skills: first, the ability to follow and repeat complex explanations (like how cold weather affects immunity) with clarity. Second, it trains you to use conversational transitions—phrases like "Well for one," "On top of this," and "Finally"—to structure your speech naturally. These skills are perfect for using the shadowspeak technique, where you mimic the speaker’s flow to improve fluency.

Listen For These Sounds

Pay attention to connected speech patterns in the dialogue. For example, "put on a jacket" often links to "putona jacket" (eliding the "t" and "o" sounds). You’ll also hear reductions like "it's called a cold" becoming "it's calleda cold" (linking "called" and "a"). These subtle links are crucial for sounding native, so practice identifying them before trying shadow speak.

Say It Like a Native

To mirror the speaker’s rhythm, focus on stress: words like "correlation," "pathogens," and "immune" are stressed on the second syllable ("cor-RE-la-tion," "PATH-o-gens," "im-MUNE"). The speaker also uses a conversational pace—pausing slightly after transitions like "So why the correlation?"—which you can mimic using the shadowing technique. Repeat short sections aloud, matching the speed and emphasis, to improve your English pronunciation. Remember: the goal is to sound natural, not perfect, so don’t rush—let the rhythm guide you.

By combining these tips with regular english speaking practice, you’ll not only understand the science behind colds but also speak English with more confidence and fluency. Try shadowing the video today—you’ll be surprised how quickly your skills improve!

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
