Can't sleep? It may be aging you.
Scientists and physicians at University Hospitals Case Medical Center, in Cleveland, conducted a first-of-its-kind clinical trial and found that sleep quality affects skin function and aging. The recently completed study was commissioned by cosmetic company Estee Lauder.
The study demonstrated that poor sleepers had increased signs of skin aging and slower recovery from environmental stressors such as ultraviolet radiation.
The study involved 60 premenopausal women between the ages of 30 and 49. Half of the women fell into the poor-sleep-quality category. The classification was made on the basis of average duration of sleep and the Pittsburgh Sleep Quality Index, a standard questionnaire-based assessment of sleep quality.
Those who slept well recovered more easily from stress on the skin, such as sunburn.
