In a ground-breaking new study, Swedish researchers have reached this startling conclusion:
“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 fine lines, and more droopy corners of the mouth. People also looked sadder when sleep-deprived than after normal sleep, and sadness was related to looking fatigued.”
I’m no scientist, but my layman’s understanding of this information is that tired people look tired and other people can see that they look tired.
Thank you, Swedish researchers. I anxiously await the results of your follow-up study, “To what extent can scientists dupe others into funding scientific studies designed to prove the painfully obvious?”
