RoseTracker| Researchers using the Pittsburgh Sleep Quality Index survey have determined that poor sleep quality increases inflammation in the body, a risk factor for heart dosease and stroke. Alanna Morris, MD, a cardiology fellow at Emory University School of Medicine says that acute sleep deprivation — defined as less than six hours in this study — had higher levels of three inflammatory markers: fibrinogen, IL-6 and C-reactive protein.
In particular, average C-reactive protein levels were about 25 percent higher (2 milligrams per liter compared to 1.6) in people who reported fewer than six hours of sleep, compared to those reporting between six and nine hours. via Science Daily
There is a healthy sleep-time zone emerging in all recent studies, that hovers around six-seven hours.
