How did you feel when you woke up this morning?
If your answer is anything other than "refreshed," maybe you should take a closer look at your sleep quality, said Michael Decker, Ph.D., an associate professor at Georgia State University and spokesman for the American Academy of Sleep Medicine.
"We should feel good when we wake up, not tired and exhausted," Decker told HuffPost. "That may indicate that something is happening during sleep that we're not aware of."
Sometimes it's not just an issue of not getting enough sleep -- it's a matter of getting good quality sleep, Decker said. Poor sleep quality has been linked in studies to increased inflammation (which can lead to heart disease and stroke), high blood pressure, and increased blood glucose levels and insulin resistance among people with Type 2 diabetes. Getting good, quality sleep -- on the other hand -- is linked with a longer life, PsychCentral reported.
Sleep quality "is important -- it's not not just the duration of sleep, but the quality that determines health outcomes," he said. "We feel better when we sleep for the right amount of time. That's the foundation of where to start."
