Hit the hay, catch some z’s, get some shut eye, take 40 winks, turn in. What a lot of ways to say sleep!

Long been a part of our vernacular, new research shows that beauty sleep is in fact a very real thing. According to a new study published by the Royal Society of Open Science, men and women are deemed more attractive after a good nights’ sleep.
