SLEEPING six hours or less per night quadruples your chances of catching a cold, researchers claim.
Seven hours' kip or more boosts the body's ability to fight the virus, they found.
Lead researcher Dr Aric Prather, from the University of California, said: "It goes beyond feeling groggy or irritable. Not getting sleep fundamentally affects your physical health."
His team looked at sleep patterns of 164 volunteers for a week then exposed them to the common cold virus and monitored their health for another week.
They found poor sleep in the week before exposure to the virus increased the risk of developing cold symptoms by 4.2 times the week after.
Dr Prather said in the study published in the online version of journal Sleep: "Short sleep was more important than any other factor. It didn't matter how old people were, their stress levels, race, education or income or if they were a smoker. Statistically sleep still carried the day.
"In our busy culture, there's a fair amount of pride about not having to sleep and getting work done.
"We need to drive home that sleep is a critical piece to our well-being."
