Cold in winter: You know that feeling when your throat starts to tickle in December, and you know what’s coming? The cough, the sniffles, the tissue pile that could fill a small bin. It’s like clockwork. But have you ever wondered why colds seem to hunt us down in winter, even when you’re doing “everything right”?
It’s not actually the cold weather:
Here’s a fun twist: the cold itself doesn’t make you sick. Viruses do. But the winter environment gives them a huge advantage. When it’s chilly, we spend more time indoors, breathing the same air as everyone else. If one person in your house or office catches a cold, the odds are high you’ll get it too.

Dry air also plays a sneaky role. Winter air has lower humidity, and indoor heating makes it worse. Your nasal passages dry out, and that thin protective layer in your nose that usually traps germs doesn’t work as well. So viruses get a free pass.
You might’ve noticed how your skin feels tighter, or your lips crack more in winter. The same dryness is happening inside your nose and throat. Basically, your body’s first line of defence takes a seasonal hit.
Your immune system slows down:
Ever felt more tired or sluggish in winter? There’s a reason. Less sunlight means lower vitamin D levels, which can affect how well your immune system fights off infections. Combine that with less exercise and fewer fresh fruits or veggies, and your defence squad isn’t operating at full strength.
There’s also the simple fact that cold viruses love cooler temperatures. Studies show they survive longer in cold, dry air. So even though it’s not the temperature directly making you sick, it’s still helping the enemy.
How to stop the cycle:
Now for the good part. You can’t stop winter, but you can make your body a harder target.
- Start with moisture. A humidifier in your bedroom can make a huge difference. It helps keep your nasal passages happy and hydrated.
- Stay hydrated, too. Most people drink less water in winter because they don’t feel as thirsty, but your body still needs it. Herbal teas count. Coffee doesn’t (sorry).
- Get sunlight when you can or take a vitamin D supplement if you live somewhere gloomy. It’s one of the simplest ways to help your immune system.
- And wash your hands. Old advice, but still golden. Cold viruses can live on surfaces for hours. If you touch your face after typing on a shared keyboard or opening a door, you’re practically inviting the virus in.
