Age the Skin
After a few days of missed sleep, you might notice puffy eyes and sallow skin. But these are just the beginning. Chronic sleep deprivation would result in many more serious skin issues and age your complexion. Some common symptoms include fine lines, lackluster skin, as well as dark circles under your eyes. When you do not sleep enough, the body will release more cortisol, a stress hormone. An excess amount of cortisol would break down collagen, which is an important protein that keeps your skin elastic and smooth. In addition, sleep loss would lower the release of human growth hormone, thus affecting the process of repairing and thicken skin tissue. [4]
