Sleep Reduces Cold Chances

CHICAGO (AP) - Want to lower your chances of getting the common
cold? Get some sleep. Researchers paid healthy adults to have cold viruses sprayed up their noses, and then wait five days in a hotel to see if they got sick. It turned out that people who slept a solid eight hours were much less likely to get sick than those who slept less, or who didn't sleep as well. Earlier research indicated that sleep boosts the immune system at the cell level. But Dr. Michael Irwin, a researcher at UCLA who wasn't involved in this study, says it's the first one to show that small sleep disturbances increase the risk of getting sick. The study is in the Archives of Internal Medicine.
