April 14, 2022

More people tend to get sick during the winter months, but why does this happen? Does cold weather cause more illnesses?

Our AFC Urgent Care Castle Rock team provides some helpful answers below, so keep reading!

Does Viral Activity Increase in the Winter?

Yes, it almost always does. In fact, according to the CDC, viruses like the flu (and now, the coronavirus responsible for COVID-19) hit their peak between December and February.

One of the most prevalent causes for the rise in viral infections is the cold weather. While cold weather does not increase the number of viruses, it does make our bodies' ability to fight them more challenging. Plus, winter weather creates a better environment for COVID-19 and the flu to thrive. Viruses are more prevalent throughout the winter months for a variety of reasons, as we've discussed.

Additional Causes of More Winter Viral Activity

  • Spending more time indoors. During the winter, people spend more time indoors with the windows shut, making them more likely to breathe the same air as an infectious person.
  • Colder, drier environments. The flu and COVID-19 viruses may be able to infect more people in colder, drier settings because they can survive longer.
  • Less sunlight and shorter days. We acquire less vitamin D and melatonin when we get less sunlight, which are both important in battling viruses and illnesses.

How Can I Stay Away From Viruses During the Winter?

While there's no way to completely avoid being sick with a virus in the winter (apart from hiding in your house alone for the duration of virus season), there are a few things you can do to reduce your chances, which we've outlined in the section below.

Consider being vaccinated as well as exploring the below-mentioned strategies. Vaccination is one of the most efficient ways to combat viruses, and vaccinations for two of the most common and harmful illnesses—COVID-19 and the flu—are available.

Additional Ways to Stay Healthy This Winter

  • Wear a mask. Masks are a simple way to protect yourself and others from the virus by preventing respiratory droplets from spreading.
  • Wash your hands regularly and thoroughly. Frequent handwashing helps protect against a variety of illnesses, including the flu and COVID-19.
  • Keep your hands away from your eyes, nose and mouth. Germs are less likely to enter your body if you keep your hands away from your face.
  • Avoid people who are sick.
  • Don't share personal items.
