While we still don’t know why we sleep, one thing is certain: sleep is essential for our bodies to function properly, and without it, things start to go downhill pretty quickly.

But even if you do sleep each night, the length of time you’re getting shut-eye and the quality of that sleep is important, and will affect your appearance noticeably.
