Sleep On It
How much sleep you get can make a night-and-day difference in the formation of wrinkles. During sleep, the body secretes human growth hormone (HGH). As the name suggests, HGH works to maintain healthy growth of all body tissues, the skin included.
Lack of sleep, on the other hand, triggers the release of a stress hormone, cortisol. Among its other effects, cortisol slows growth and reduces normal tissue maintenance. The skin's outer layer becomes drier and more susceptible to infection, sunlight and other harm that can lead to wrinkles.
The impact of sleep, and the lack thereof, is amplified as you reach middle age. That's when HGH production naturally tails off and wrinkles tend to develop naturally. HGH is included in some anti-aging creams and sold in supplements, but such treatments are not proven to work and may even have harmful side effects [source: Mayo Clinic]. It's best to stick with the HGH you've got and help it work to its full advantage by getting adequate sleep. For most adults, that means seven to nine hours of quality shut-eye per night [source: Morgenthaler].
But, you may ask, how can you sleep if you're worried about wrinkles? That question leads us to our last bit of advice.
