Sunlight is known to be the best and only natural source of vitamin D. But, scientists say that sunshine could give you wrinkles, even through a window.
Two studies have found that the damage caused by sun coming through glass can be so dramatic that, over time, the side of the face exposed to the rays can end up looking up to seven years older than the other.
Even a few hours sitting in a car during April results in skin damage, according to the studies.
For the first study, the scientists at the University College Hospital, Besancon, in France conducted an experiment to see how sections of face age at different rates related to exposure to sun. They demonstrated that a woman office worker or regular driver will age more quickly on the side where the skin faces the sun and heat - even through glass.
"Participants showed significantly more clinical signs of facial ageing on one side of their face due to driving or working close to windows over many years," the scientists were quoted by the Daily Mail as saying.
