Quality sleep could add years to your life, study finds

Not getting enough sleep? It could be shortening your life, a new study suggests.

According to research from the American College of Cardiology released Thursday, getting the right amount of good sleep each night can play a role in heart and overall health, which could in turn add years to your life. The data also suggests that about 8% of deaths could be attributed to poor sleep patterns.

Dr. Frank Qian, co-author of the study and clinical fellow in medicine at Harvard Medical School, told CBS News that sleep impacts many aspects of health, from hormones and metabolism to mental health and memory. From his and his team's analysis, he was most surprised with the "potential life expectancy gain... with just fairly simple sleep quality improvements."
