Want healthier cells in just 8 hours? Then get some solid shut-eye tonight.

Your body does important things while you sleep -- like healing your cells. But just one night of tossing and turning could trigger cell-damaging inflammation. So turn off the tube, slip on that sleep mask, and get your 40 winks.

Inflamed in the Membrane
In a recent study, sleep-deprived people -- especially women -- showed a marked increase in their levels of a protein called NF-kB. That's bad news, because NF-kB plays an essential role in the body's inflammation response. The study may help explain why poor sleep is associated with several inflammation-related disorders, including cardiovascular disease, arthritis, diabetes, cancer, and obesity.
