How much sleep did you get last night? What about the night before? If the answer was less than six hours each night, chances are your body's not only tired... but also unhealthy.
In Wednesday's Healthier Me, experts at the Center for Disease Control and Prevention have long thought that sleep deprivation led to an increased risk for a range of ill effects including heart disease, diabetes, high blood pressure, and obesity, and a new study published in PNAS (Proceedings of the National Academy of Sciences) has revealed that insufficient shut-eye actually causes a change in our bodies' cells.
When study participants were deprived of sleep, researchers at the University of Surrey in the U.K. discovered changes in more than seven hundred genes, particularly those known to regulate metabolism, stress, and circadian rhythms.
