A 7 to 8 hours of good sleep every day is essential for your healthy skin to be happy. But a large number of us are unable to consistently put in that much time sleeping. Unfortunately, one of the victims of sleep deprivation is your skin.So, it’s useful to know how exactly does good sleep gives you healthy skin. And, how insufficient sleep is bad for your healthy skin.
Above all, consistently getting 7 to 8 hours of good sleep is good for your skin.
First of all, blood flow to the skin improves. As a result, you get healthy skin that looks good.
Next, collagen levels increase. In fact, collagen, is a protein that promotes smooth healthy skin and elasticity.
Also, good sleep improves the texture of your healthy skin.
Most noteworthy, you perspire when you sleep. In fact, perspiration rebalances and recovers extra moisture for your healthy skin.
In addition, perspiration makes sleep a natural moisturizer that helps smooth out wrinkles on the skin.
Above all, in the first 3 hours of sleep, your body produces somatotropin, the human growth hormone. And, somatotropin is released from your pituitary gland. Most of all, it helps your skin repair damage that occurs every day. In addition, it stimulates collagen production in the skin.
Next, in the middle two hours of sleep, melatonin levels increase. Moreover, melatonin acts as an antioxidant that helps protect your healthy skin from damaging free radicals.
Finally, in the last 3 hours of sleep, cortisol levels decrease. As a result, inflammation decreases. In addition, your skin gets its deepest recovery of the night.
On the other hand, sleep deprivation has many negative effects on your healthy skin.
Furthermore, the same studies reported the following.
First of all sleep deprivation cause your body to release the stress hormone cortisol. Especially relevant, the cortisol inhibits fibroblast function and increases matrix metalloproteinases (collagenase, gelatinase). Furthermore, matrix metalloproteinases accelerates collagen and elastin breakdown.
But, both collagen and elastin are essential for skin integrity. So, when collagen breaks down, skin elasticity decreases. And, poor skin elasticity causes your skin to look wrinkled and saggy.
In addition, the skin shows signs of aging by becoming thinner and less firm. In fact, when skin is thin, its appearance is less smooth and subtle. As a result, wrinkles become more prominent and you get not so healthy skin.
Also, studies have reported that sleep deprivation (even as little as less than 7 to 8 hours of sleep) increases levels of inflammatory markers in the blood, like C-reactive protein and interleukin. In addition, other studies have similarly reported that sleep loss triggers key cellular pathways that produce tissue-damaging inflammation.
Moreover, inflammation has several negative effects on your healthy skin:
In addition, sleep deprivation causes your healthy skin to become more sensitive. In fact, signs of sensitive skin are:
Also, sleep deprivation causes dark circles under the eyes because of dilated blood vessels.
In addition, sleep deprivation causes brown spots to occur on your healthy skin.
Next, sleep deprivation impairs your skin barrier function. First of all, the skin barrier is the outermost layer of your skin, known as the stratum corneum. In fact, the skin barrier is designed to be tough and hard to penetrate. As a result, the skin barrier helps prevent water loss from your healthy skin.
Moreover, the skin barrier also keeps out irritants, macro organisms, and other pollutants that might disturb the rest of your skin organ.
So, when your skin barrier function isn’t working well, foreign invaders penetrate the skin. As a result, your skin ends up looking red and irritated. In addition, the skin loses water, which makes your skin become dry and flaky.
And, not getting the full, first 3 hours of sleep causes you to lose the full benefits from the human growth hormone. As a result, repairing skin from daily damage, does not fully occur. And this induces the aging process.The daily damage to the skin happens for several reasons, including:
Also, sleep deprivation causes you to become tired. As a result the blood in your body is not flowing efficiently, which results in lack of oxygen in the blood. And, this lack of oxygen causes your skin to appear ashy, pigmented or blotchy. In fact, ashy skin has a white or gray coloring that really shows up on skin with darker pigmentation.
Sleep deprivation causes your complexion’s pH level to drop. Consequently, your previously healthy skin looks less youthful and has less of a glow.
Also, when your skin’s pH level drops, there is an imbalance. As a result, your skin stops producing the moisture it needs which causes the skin to look drier. And dry skin likely results in one or more of the following signs:
Finally, sleep deprivation causes your healthy skin to look pale and dehydrated. And there are four signs that tell you if your skin is dehydrated.
