'Sleeping longer doesn't necessarily mean you're sleeping well,' the president of the American Academy of Sleep Medicine said.
You've likely heard that not getting enough sleep can be detrimental to your health, but that doesn't mean sleeping for too long is good for you either.
People who get too little sleep (six hours or less) or too much shut-eye (10 hours or more) are more likely to have coronary heart disease, stroke and diabetes, a new study from the Centers for Disease Control and Prevention suggests.
Adults, especially those with chronic conditions, should aim for seven to nine hours of sleep a night, according to the American Academy of Sleep Medicine.
"Sleeping longer doesn't necessarily mean you're sleeping well," Dr. M. Safwan Badr, president of the AASM, said in a release. "It is important to understand that both the quality and quantity of sleep impact your health."
The CDC study involved more than 54,000 participants age 45 and older. Almost one-third were classified as short sleepers, while 64% were identified as optimal sleepers. Roughly 2% were long sleepers.
