why do we get cold - #23071
I am really confused about something — why do we get cold? Last week I was out with my friends and it was kinda chilly, but not freezing or anything. Next thing I know, I wake up the next morning with that scratchy throat and a runny nose. It’s like my body just decided, “Hey, time to catch a cold!” But seriously, why do we get cold like this? I thought I was bundled up enough, but clearly not. Also, I keep hearing different things from people about how it happens. Is it true that you can just “catch” a cold from being in the cold, or is it all about germs and stuff? I mean, I know there’s gotta be a science-y explanation behind this, right? Like, do we get cold just because the temp drops, or is it because there are more viruses around in the winter? I’m sitting here wondering if all those times I went outside with wet hair contributed to this, or if I was just destined to get sick because of the season? It’s super frustrating! I have a busy week ahead and can’t afford to be sneezing through meetings. What can I do to avoid getting cold again? Why do we get cold anyway?

Doctors' responses
Colds, or the common cold, are primarily caused by viruses, especially the rhinoviruses. When you get that scratchy throat and runny nose, it’s because one of these viruses has managed to penetrate your body’s defenses, usually through the respiratory tract. Cold weather itself doesn’t directly cause colds; rather, it’s the environment during colder months that facilitates the spread of these viruses. When the temperature drops, people tend to stay indoors more often, increasing close contact with others, which helps viruses spread. Also, cold and dry air can dry out your nasal passages, reducing their ability to trap and expel viruses efficiently.
As for old wives’ tales about wet hair or being inadequately dressed, these don’t really hold up scientifically for causing colds. However, being in the cold may indirectly affect your body’s immunity by stressing the body a bit, but the viruses are the main culprits. To prevent future colds, focus on good hygiene: wash your hands often, avoid close contact with sick individuals, and avoid touching your face unnecessarily. Keeping your immune system strong by getting plenty of rest, eating a balanced diet, and managing stress can also be helpful. During peak cold seasons, consider increasing your intake of vitamin C and zinc, as there’s some evidence they might help shorten colds if they do happen. If you feel symptoms coming on, like a sore throat or stuffy nose, rest up and stay hydrated to give your body the best chance to fight back quickly. If your condition worsens or doesn’t improve, it’s prudent to seek medical attention, since some symptoms might actually indicate something more serious than a cold.
