Study reveals the face of sleep deprivation

A new study finds that sleep deprivation affects facial features such as the eyes, mouth and skin, and these features function as cues of sleep loss to other people.

Results show that the faces of sleep-deprived individuals were perceived as having more hanging eyelids, redder eyes, more swollen eyes and darker circles under the eyes. Sleep deprivation also was associated with paler skin, more wrinkles or frown lines, and m!re droopy corners of the mouth. People also looked sadder when sleep-deprived than after normal sleep, and sadness was related to looking fatigued.

Then you get home and you don’t go to bed early enough because this is the only me-time you get, damn it, and if you want to watch three hours of Netflix, then you will. Or you try to go to sleep but you fail and end up tossing and turning, because sleeping is actually kind of hard, and the more you want it, the more it slips through your grasp.

But maybe the knowledge that you aren’t sleeping enough is part of what’s keeping you trapped in your swamp of lethargy during the day. Maybe if you were sweetly, blithely ignorant of your somnial failings, you’d feel more chipper and work more efficiently. In a recent study published in the Journal of Experimental Psychology, researchers from Colorado College tested the effects of being told you’re getting enough sleep—“placebo sleep,” as they call it.
