SLEEP + YOUR SKIN
It turns out there’s quite a bit of research and science behind the concept of 'beauty rest'. Sleep is when some of the most important internal and epidermal recovery takes place.
You can almost immediately tell that getting a poor night of sleep doesn’t do 'woke-up-like-this' wonders for your face.
First and foremost, you should understand that sleep is the time when your body repairs itself. This is true for your epidermis as much as it is for your brain or your muscles. During sleep, your skin’s blood flow increases, and the organ rebuilds its collagen and repairs damage from UV exposure, reducing wrinkles and age spots.
If you don't sleep, your body doesn't make as much human growth hormone (which stimulates cell production), so your skin won't be as thick. Without time to produce new, fresh cells and fix yesterday's damage, you're practically welcoming accelerated aging—plus, collagen may prematurely stiffen. Yikes.
