My parents always told me to wrap up warm or I'd catch a cold. I thought they worried too much, but it turns out they might have been onto something...

Yale University researchers have discovered that the common cold virus thrives in cooler conditions, such as inside your airways when you breathe in frosty winter air.

The low temperature also seems to prevent a full immune response to the virus, so you're less likely to fight it off than when the weather's warm. Looks like science mum has been proved right!
