What do you see in the mirror after a sleepless night? You look pretty badly, don’t you? Sour skin is gray. There are circles under your eyes. You look as if you were ill, don’t you?
I have just seen a video in which maker-ups show men and women what happens to their facial skin if they do not sleep enough. Then, they use makeup to hide the effects. The results were shocking. The participants decided that they will change their sleeping habits.
If you do not sleep enough not only you look worse, but also people treat you differently. Your face holds a lot of information about you that has effects on how we treat each other.
A tired face is the sign of illness, and other people will talk with us like that, even if you feel happy and balanced.
The results show that sleep deprivation affects features relating to the eyes, mouth, and skin, and that these features function as cues of sleep loss to other people. Because these facial regions are important in the communication between humans, facial cues of sleep deprivation and fatigue may carry social consequences for the sleep deprived individual in everyday life.

Also, another study has proved that there is a connection between poor sleep and the aging of the skin. On top of that, in those people who sleep less, the skin regeneration processes are not so efficient as well. These skin regeneration processes are responsible for curing the wounds and the burns made by sunlight. (Read the study here)
