You know you’re supposed to score eight hours of z’s a night, but let’s be honest: We’re all guilty of neglecting shuteye. We’re all tired. The American Center for Decease Control (CDC) even considers insufficient sleep a public health problem. But sleeping less isn’t just detrimental to your physical health, lack of sleep has been linked to serious issues including diabetes, heart disease, depression, and obesity, it wreaks havoc on your skin, too. Keep reading to learn how.
Skin gets stressed out, more breakouts
It shouldn’t come as a surprise that the pesky stress hormone cortisol can tank your skin health like it tanks your physical health. The science: Cortisol levels naturally decrease while we sleep. That’s a good thing, lower levels of cortisol allow your skin to regenerate and protect itself. Miss out on sleep, though, and that cycle is disrupted. Persistently high cortisol levels can interfere with how well our bodies heal and can promote acne breakouts.
2. Good night’s sleep leads to younger looking skin
Back to cortisol: At high levels, the hormone contributes to the breakdown of collagen, a protein that’s key in helping your skin look young and fresh, and elastic tissue. What it means is premature aging. The other issue is that 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, leading to fine lines and wrinkles.
3.Your defence system weakens
While we sleep, our skin cells rev up production of protective antioxidants for the next day. That’s important, considering that antioxidants – our body produces some of them, and we take them in through fruits, vegetables, or skin-care products – can reduce free-radical damage to the skin from UV rays.
4.Your skin will be thirsty after an all-nighter
Dry, flaky skin is never cute. But spend too much time away from the bedroom and it’s practically guaranteed. Lack of sleep can promote inflammation along with skin-barrier dysfunction, leading to lack of hydration.
5.Not going to look your best without a solid night’s rest
Inflamed, dull, and dry, that’s what you can expect after a night of little rest. According to a recent Swedish study redder, more swollen eyes, dark circles, and paler skin are characteristic of a night of no sleep. The same study also found that sleep-deprived people were perceived to look sadder than they did after a good night’s sleep.
