82/100

Cold weather does not directly cause colds, but lower temperatures and low humidity are associated with higher common-cold risk and may help rhinoviruses spread and replicate more effectively.

~ Both Sides ~

For The Claim

A 2009 population study found common-cold risk rose as temperature fell, with a 2.1% risk increase per 1°C decrease.
Reuters reported Yale findings that colder nasal conditions weaken innate immune response and boost rhinovirus replication.
Nature summarized the same lab work and linked cold upper airways to winter cold seasonality.

Against The Claim

Mayo Clinic says cold weather itself does not cause the common cold; viruses do.
The winter effect may be partly explained by more time spent indoors and closer contact with sick people.
The evidence is strongest for low temperature and low humidity as contributing factors, not for cold weather alone as a sole cause.

Bottom Line

The claim is too broad as written. Evidence supports an association between colder, drier conditions and higher cold risk, but not that cold weather alone directly causes catching a cold.

~ What We Couldn't Find ~

I searched for current, direct evidence on whether outdoor cold alone raises individual cold-catching risk; the strongest sources mostly support temperature and humidity as contributing factors rather than weather as a sole cause.
