Sleep is so important for all of the body’s systems and their functioning. As far as the skin is concerned, lack of sleep causes the stress hormone cortisol to be released, which in turn encourages inflammation in the skin, causing flare-ups in conditions like acne, psoriasis, and even eczema.
The National Sleep Foundation recommends seven to nine hours of sleep per night for most adults. Less than that can play a role in the development of wrinkles, sagging skin, and dark circles under the eyes. The reason? During sleep, your body delivers fluids to organs and tissues that need replenishing, while removing excess fluids from other areas. Cutting this process short is one reason sleep-deprived people often have under-the-eye bags (i.e., pockets of fluid). Skimping on sleep also increases levels of inflammation and stress hormones, which can destabilize your immune system, aggravating skin problems like acne, psoriasis, and eczema. Also, during sleep, the body releases human growth hormone, a necessary ingredient for collagen production—the protein that gives people shiny hair, strong nails, and glowing skin. Skimping on sleep raises cortisol levels, which can interfere with collagen production. If bedtime has drifted later and later recently, try moving it forward in 15-minute increments over the course of a week or two until you achieve at least a seven-hour minimum.
In addition, developing a healthy nighttime skin-care routine can make an impact on how skin looks in the morning!
