Researchers used frequent telephone  4  to track the sleep  5  of more than 150 men and women aged 21 to 55 over the course of a few weeks. Then they  6  the subjects to the virus, quarantined them for five days and kept  7  of who got sick.

  8  sleeping more, sleeping better also seemed to  9  the body fight illness: Patients who fared better on a measure  10  as 'sleep efficiency' - the percentage of time in bed that you're actually sleeping - were also  11  likely to get sick.

The results held  12  even after researchers  13  for variables such as body-mass index, age, sex, smoking and pre-existing antibodies to the  14  .

In plain English, maybe tossing and turning when you're  19  with the cold virus  20  to the symptoms that define a cold.

The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health.
