Fluff up the pillows and pull up the covers.Preventing the common cold may be as easy as getting more sleep.
Researchers paid healthy adults $800 to have cold viruses sprayed up their noses,then wait five days in a hotel to see if they got sick.Habitual eight-hour sleepers were much less likely to get sick than those who slept less than seven hours or slept fitfully.
"The longer you sleep,the better off you are,the less susceptible you are to colds," said lead author Sheldon Cohen,who studies the effects of stress on health at Pittsburgh's Carnegie Mellon University.Prior research has suggested that sleep boosts the immune system at the cell level.This is the first study to show small sleep disturbances increasing the risk of getting sick,said Dr.Michael Irwin,who researches immune response at the University of California,Los Angeles,and was not involved in the study.
"The message is to maintain regular sleep habits because those are really critical for health," Irwin said.
