Cold Weather and the Common Cold
People spend more time indoors during cold weather, which increases the chance that viruses will spread to you from someone else.
Cold weather can make the inside lining of your nose drier and more vulnerable to viral infection.
During the colder months of the year, when the humidity is low, the most common “cold causing” viruses survive better.
But… there is no evidence that you can catch the common cold from exposure to cold weather or from getting chilled or overheated.
