Restoration Sleep Protects Skin A study in the journal Clinical and Experimental Dermatology found that people who slept seven to nine hours a night had skin that could protect and heal itself better after being exposed to ultraviolet light compared to those who slept five hours or less.Skin goes through much of its restoration while you sleep. If you cut back on sleep, you are reducing the amount of time the skin has to repair, which can affect the way you look.Skin cells regenerate more quickly at night. Collagen, the protein responsible for helping your skin keep its volume and elasticity, is produced as the skin cells regenerate. There is also more blood flow to the skin during sleep, which delivers the nutrients it needs to recover from a day of exposure to the elements. Boost Your Skin Care at NightNight time is a good time to apply moisturizing and retinol skin care products since the increased blood flow can help those ingredients work more efficiently. Sleeping on your back or side instead of your face is a good idea in order to avoid creating sleep wrinkles that can deepen over time.Just like using sunscreen, having a clean and healthy diet, incorporating daily movement, hydrating well, taking time to reflect, and having a good social connection, sleeping for seven to nine hours nightly can make a noticeable difference in how well you age.Cheers to your health!
