Washington: A new study has found that people who stayed up for nearly a day and a half looked sadder and had more apparent wrinkles than when they were well-rested.
The study now confirms that your best beauty trick is to get a good night`s sleep, according to the New York Daily News.
Findings revealed what you`ve probably seen in the mirror after a rough night: sleep-deprived people look more, shall we say, worn-out, with redder, more swollen eyes, darker under-eye circles, more wrinkles and droopier eyelids and mouths than their well-rested selves.
People also looked sadder when sleep-deprived than after a normal sleep, and this apparent sadness was related to looking fatigued, the researchers said.
Tina Sundelin, author and doctoral student in the department of psychology at Stockholm University in Stockholm, Sweden said that since faces contain a lot of information on which humans base their interactions with each other, how fatigued a person appears may affect how others behave toward them
She added that this is relevant not only for private social interactions, but also official ones such as with health care professionals and in public safety.
