Research has found the hours of sleep you get each night can dramatically affect your chances of catching a cold.
Researches at the University of California analysed the sleep patterns of 164 volunteers for a week, before exposing them to the common cold virus.
Results showed that those who had less than six hours sleep a night the week prior to exposure we're 4.2 times more likely to develop cold symptoms than those who got more than seven hours of rest.
Dr Prather, who led the research, has urged people to put more importance on sleep as key to their overall well-being, following his findings. He said: "It goes beyond feeling groggy or irritable. Not getting sleep fundamentally affects your physical health. In our busy culture there's still a fair amount of pride about not having to sleep and getting a lot of work done. We need to begin to drive home that sleep is a critical piece to our well-being."
