Sleep in important for numerous bodily functions. You’d think that the maximum that sleeplessness can do is give you dark circles under your eyes and a few yawns that you can cleverly try to disguise in the meeting room. However, these effects are only the tip of the iceberg.

Wakefulness correlates with multiple health concerns including increased risk of developing diabetes type II and cognitive decline. When you snooze, your skin heals and repairs. So, when you steal hours from your sleep, you not only get dark circles under your eyes but also hit the aging note early among other things.

Hence, when they say that you need your beauty sleep, they aren’t bluffing at all. Have a look at how sleep impacts your skin:

First three hours of sleep

During the first three hours of your sleep, your body starts to produce the human growth hormone. As we climb the age ladder, this hormone from the pituitary gland is essential for maintaining the radiance and youth of your skin. If this hormone is not released, it can culminate in daily damage to your skin and subsequently induce the aging process.

The middle two hours of sleep

This duration of your slumber is when melatonin is released. The hormone is not only responsible for regulating your circadian rhythm but also serves as an antioxidant. In its role as an antioxidant that fights free radicals.

The last three hours

During this last phase of your sleeping, the levels of the stress hormone or cortisol decline. At the same time, the skin’s temperature drops so that the muscles relax, which allows your skin to recover.

This is how your sleep works on your skin’s healing and repair. Let’s walk you through how your skin suffers when your compromise with your sleep:

Dull skin

Wakefulness boosts the levels of cortisol. This triggers inflammation that leads to a dull skin as well as skin swelling and redness. At the same time, less sleep translates into tiredness. This means that the blood in your body doesn’t flow efficiently which results in a lack of oxygen. This, in turn, makes your skin pigmented, ashy, or blotchy.

Dry skin

When your body sleeps, your body’s hydration rebalances and recovers. This means that your sleep is a natural moisturizer, which helps to soothe out wrinkles. Missing sleep affects your skin’s moisture levels and lowers your complexion’s pH levels.


Restlessness leads to chronic stress that affects the collagen integrity of your skin. It a critical ingredient that maintains your skin’s elasticity and firmness. When collagen is broken down, with a lack of slumber, your skin shows noticeable aging signs including thinner skin. This makes your skin less smooth.

Less skin rejuvenation

Your body reaches a stage of equilibrium when you sleep. During this time, the cells use the low energy expenditure and dedicate it to facilitate cellular repair and rejuvenation. This is why you need to sleep properly so that your skin can repair.

A 2014 study examined the skin’s appearance and water loss in a pool of 60 women participants. It concluded that good sleepers had a protected skin barrier and were more satisfied with the way they look. These women were also able to better deal with the intrinsic causes of skin aging.

Your skin better absorbs certain products

In the sleep stage where your skin renews, it is better able to absorb certain products. This means that you will get the best impact from the anti-aging ingredients that you use. This is why Mona Gohara, MD, associate clinical professor of dermatology at Yale School of Medicine suggests, “Put the heavy hitters on at night, like retinols and glycolic acid.”

Summing up, sleep is very critical for your health as well as skin.
