Does Cold Weather Cause Colds? 


Short answer:


Long answer:

It’s complicated.


But first, what even is a cold? Colds are caused by a variety of viruses, including rhinovirus, respiratory syncytial virus, influenza, parainfluenza, and nearly 200 more. Its symptoms include a sore throat, runny nose, sneezing, watery eyes, and mucus draining from your nose and throat. You can catch a cold by touching something with cold-causing viruses on it then touching your face, or by breathing in virus particles through the air.


While none of this is directly related to the weather, it can still indirectly affect your chances of getting a cold. For example, cold viruses can infect your body through the lining of your nose and throat. When the weather gets colder, this lining becomes thinner and more vulnerable to infection. Another way that cold weather can affect your chances of catching a cold is by increasing the amount of time you spend inside with less air circulation. This leads to you breathing the same air as other people and being more vulnerable to infection.


Essentially, a cold is not caused by cold, but cold weather could cause colds to be more common. Cool!
