“美容觉”的确有作用

Beauty sleep is a real thing, according to researchers who have shown that people who miss out on sleep do appear less attractive to others. , ,“美容觉”确有其事。研究人员表示，比起睡得好的人 ，睡眠不足的人显得没有那么光彩照人 。, ,A couple of bad nights is enough to make a person look "significantly" more ugly, their sleep experiments suggest. , ,Dark-circled "panda" eyes and puffy lids can even put others off socialising with you, they say. , ,People were rated by strangers as less healthy and approachable when they had tired faces. , ,The Karolinska Institute researchers says this makes sense in evolutionary ¹ terms. , ,"An unhealthy-looking face, whether due to sleep deprivation ² or otherwise, might activate ³ disease-avoiding mechanisms ⁴ in others." , ,In other words, people don't want to hang around with people who might be ill, whereas someone who looks energetic and fit will hold lots of appeal.
