Sleep deprivation ages skin
Getting poor sleep can affect the way your skin ages and functions, according to new research from University Hospitals Case Medical Center in Cleveland. The study, commissioned by skin care product manufacturer Estée Lauder, found that people who don’t sleep well had increased signs of skin aging and recovered more slowly from environmental stressors, such as sunburn. This was the first study to conclusively show a link between poor sleep and weakened skin health, according to the researchers.
The scientists observed 60 pre-menopausal women between the ages of 30 and 49, with half of the participants reporting poor sleep quality. The study involved a visual skin evaluation and several tests of the skin, including UV light exposure and skin barrier disruption. Participants also filled out a sleep log for a week to detail their slumber habits. The researchers found significant differences between good and poor quality sleepers. Poor sleepers showed increased signs of intrinsic skin aging, including fine lines, uneven pigmentation and reduced elasticity.
Skin health is not the only problem tied to sleep deprivation. Previous studies have connected it to the development of obesity, diabetes, cancer and immune deficiency.
