A good night's sleep can mean good skin health because when you're sleep -- deprived, your body makes more of the stress hormone cortisol. Elevated levels of cortisol can lead to increased stress and inflammation in the body, hurting your skin's quality.
But the relationship between skin health and lack of quality sleep can be a vicious cycle, especially with conditions like atopic dermatitis or eczema, which can lead to scratching even through the night, recent research published in the journal Clinics in Dermatology showed.

"Poor sleep can lead to increased stress hormones in the body that increase the severity of inflammatory skin conditions such as acne or psoriasis,” explains Jessica Krant, M.D., MPH, assistant clinical professor of dermatology at SUNY Downstate Medical Center and founder of Art of Dermatology in New York. This can result in increased itching, which can disrupt sleep. As the vicious cycle continues, skin conditions and sleep quality can increasingly worsen together. In contrast, skin conditions and sleep quality can also improve together. Getting a good night's sleep will help to clear up skin, which allows sleep to improve and, in turn, will improve skin health."
Need more convincing? Here are six reasons why not getting enough sleep detracts from skin health and your health in general:
Not Enough Sleep Worsens Existing Skin Conditions
Increased inflammatory response shows up as increased acne breakouts, increased skin sensitivity, increased allergic contact dermatitis reactions and increased irritant dermatitis -- and more severe conditions mean more treatment and skin care.
Not Enough Sleep Detracts From Your Skin's Natural Beauty
Increased inflammatory cells in the body lead to an increase in the breakdown of collagen and hyaluronic acid, the molecules that give the skin its glow, bounce and translucency.
Not Enough Sleep Makes Immune-Related Skin Problems Worse
Increased inflammation in the body throws off the body's ability to regulate the immune system, which leads not only to getting sick more often, but also to flares of immune-related skin diseases such as psoriasis and eczema. Psoriasis is not just a skin disease; it's also an indicator of body inflammation. "Many people with severe psoriasis actually have an increased risk for heart attacks, which is even more reason to keep stress low and get good quality sleep," Dr. Krant says.
Not Enough Sleep Results In Less Beauty
While you're sleeping, the body's hydration rebalances. Skin is able to recover moisture, while excess water in general in the body is processed for removal. Not getting enough sleep results in poor water balance, leading to puffy bags under your eyes and under-eye circles, as well as dryness and more visible wrinkles.
Not Enough Sleep Accelerates The Aging Process
During deep sleep, the rise in growth hormones allows damaged cells to become repaired. Without the deeper phases of sleep, this won't occur, allowing daily small breakdowns to accumulate instead of being reversed overnight. This results in more noticeable signs of aging.
Not Enough Sleep Contributes To Weight Gain
Sleep also helps with weight management, which is good for your skin. Sleep makes you feel less hungry, Krant explains -- recent studies have linked sleep deprivation to excess snacking and calorie consumption.
Getting A Good Night's Rest
Here are tips from Krant for getting good sleep and better skin health:
- Don't eat a big meal too late in the day.
- Drink plenty of water throughout the day, but not late at night.
- Sleep under a warm blanket in a cool, dark, quiet room.
- Keep electronics out of the bedroom.
- Use breathable cotton sheets and wash them regularly, so they don't collect dust mites and bacteria.
- Use laundry detergents that don't have strong fragrances, which can be irritating to skin.
- Getting your beauty sleep isn’t an old cliché -- it's a must for having skin that glows.
