Police are reminding people of the dangers of hypothermia after two people who collapsed in freezing temperatures needed hospital treatment.
A woman in her 30s was found in Market Street, Kidderminster, Worcestershire, at about 0100 GMT on Friday.
A man in his 40s was discovered face down in the snow in Castle Road in the town on 18 December and was believed to have been there for some hours.
They had both been drinking and were close to hypothermia.
The man was found at about 0630 GMT and was "very lucky" to be found by a member of the public who was going to work early, police said.
Insp Paul Crowley, of West Mercia Police, said: "Had he not been discovered when he was, he may well have died."
The force urged groups of friends to look out for each other and stay together, and reminded revellers to ensure they made arrangements to get home safely, such as booking a taxi.
