Despite being called the common “cold,” lower temperatures alone won’t make you sick. In fact, the exact opposite is true. “Cells that fight infection in body actually increase if you go out into the cold,”. It’s your body’s way of combatting the stress of freezing temps. Plus, according to the National Institute of Allergy and Infectious Diseases, cold viruses grow best at about 91 degrees; if you’re outside in the cold, your nostrils are surely colder than that.
