It’s no secret that sleep has a great effect on how you look. If you don’t get quality zzz’s, you’ll easily look tired and haggard. If you get to sleep more, you’ll most likely look nice and fresh. But did you know that getting enough sleep can also help you look smarter?
According to a study by the University of St. Andrews researchers, getting more sleep can actually make you appear more intelligent than your peers and even teachers because of the natural expression that they can make with a full night’s rest. The study notes that people with droopy eyes and a slight frown are perceived to be less intelligent by many. These are related to sleep because not getting ample zzz’s can definitely result in this facial expression in a person. So those who look alert with more open eyes tend to exude a more intelligent vibe to those around them.
You might argue that all of these sound really circumstantial, but there’s more to the study, really. The researchers have collaborated on a trial with a team of researchers from the Swedish Karolinska Institutet. They took the participants’ photos after a full night of sleep and another after a night of restricted slumber. This resulted in the same individuals to have less openness of their eyelids, which made them appear to be less intelligent to other participants. So, in short, if you look sleepy and tired, you also look less intelligent.
The lead researcher of this study, Sean Talamas, explained why more sleep makes you appear smarter:
“People over generalise in judging those with droopy eyelids and a frown as being tired and having a low mood, both of which have a well-documented detrimental effect on cognitive performance.
“Therefore it should be no surprise that many of us find people who look less alert and who have a lower mood as less intelligent looking.”
So, if you’ll ever find yourself nearing a situation where you want to appear smarter, get some solid sleep the night before. This might just help you land a job, appointment, or a deal without a fuss.
