Can you catch a cold just from going outside with wet hair in winter?

No. Colds are caused by viruses, not by feeling cold.

  1. Yes, the cold weakens you instantly
  2. No, you need to catch a virus ✔
  3. Yes, cold air freezes your lungs

Why: You can only catch a cold if you come into contact with a cold virus. Being chilly might make you shiver, but it cannot create a germ.

Huh, didn't know that: People get sick more in winter because they stay indoors, breathing the same air as infected people.

The dad joke
