According to a new study published in the Jan. 12 issue of Archives of Internal Medicine, the amount of sleep you get is directly linked to your risk of catching a cold. If you get less than seven hours of sleep a night, you're three times more likely to catch a cold. And if you're tossing and turning all night, you're five times more like to catch a cold.
Researchers say this is the first study to show that anything less than seven to eight hours of sleep—good, solid sleep—a night can lower your resistance to the common cold virus. So for the sake of your own health, and the health of those around you, try to catch a few more zzzzz's.
