If you sleep for more than 8 hours per night, chances are you will not catch a cold, research has proved.
The study appears in the journal Archives of Internal Medicine.
A team from Carnegie Mellon University found the risk was trebled compared with those who sleep for eight hours or more a night.
A lack of sleep impairs the immune system and the body’s ability to fight off the viruses that cause colds and flu.
Volunteers who spent less than 92% of their time in bed asleep were five-and-a-half times more likely to become ill than those who were asleep for at least 98% of their time in bed.
Professor Ron Eccles, director of the Common Cold Centre at the University of Cardiff, said sleep and the immune system were closely linked.
He said: “I do believe there is enough information on this to indicate that lack of sleep or sleep disturbance will reduce our resistance to infections such as colds and flu.”
Does this mean that a lie-in is actually healthy, would your Boss be happy if you slept more and turned up late for work but were never sick? We thought not..
