Experts have raised many questions about the safety of sunscreens and the chemicals they contain. But a study at University Hospitals (UH) Case Medical Center, Cleveland, has found that an all-natural sunscreen can slow skin aging, help your skin function better and even improve healing from sunburn.
The sunscreen touted by the researchers: sleep.
In research funded by Estée Lauder, scientists found that people who consistently enjoy a good night’s sleep have skin that shows fewer signs of aging, copes with sun exposure more effectively and detoxifies faster.
“Our study is the first to conclusively demonstrate that inadequate sleep is correlated with reduced skin health and accelerates skin aging. Sleep deprived women show signs of premature skin aging and a decrease in their skin’s ability to recover after sun exposure,” says researcher Elma Baron. “Insufficient sleep has become a worldwide epidemic. While chronic sleep deprivation has been linked to medical problems such as obesity, diabetes, cancer and immune deficiency, its effects on skin function have previously been unknown.”
This research examined five dozen women, ages 30 to 49, evaluated their sleeping habits and analyzed the health of their skin.
The study demonstrated significant differences between good and poor quality sleepers. Poor sleepers had more lines on their faces, uneven coloring and less skin elasticity.
In addition, the good sleepers recovered faster from sunburn and skin inflammation.
“This research shows for the first time, that poor sleep quality can accelerate signs of skin aging and weaken the skin’s ability to repair itself at night,” says researcher Daniel Yarosh. “These connections between sleep and skin aging, now supported with solid scientific data, will have a profound effect on how we study skin and its functions.”
