Believing you "caught a cold" from chilly weather is a common myth.
Colds aren't caused by low temperatures but by over 200 viruses, mainly rhinoviruses and coronaviruses, floating in the air. You could go sleeveless at 10°C in the rain and stay healthy without viral exposure.
So why do colds surge in winter?
Cold indirectly contributes: dry air weakens nasal mucous membranes, making them prone to infection. We huddle in crowded indoor spots like malls and cafes, or cram onto public transport instead of walking. This boosts virus transmission via air or contaminated surfaces. Counter it by avoiding crowds and basic hygiene, like handwashing after sneezing or nose-blowing.
