Sleep is Skincare: Sleep, Aging, and your Skin
In TCM, the skin is the outer manifestation of the blood. When you sleep, blood returns inward to nourish the organs and regenerate tissues, including the skin. With adequate sleep blood and yin and replenished and the skin appears supple, moist, and luminous. When sleep is poor or insufficiency the blood and yin become deficient the skin becomes dry, thin, dull, and prematurely aged. Common signs of blood and yin deficiency in the skin are dryness and flaking, fine lines, dull or pale complexion, and increased sensitivity.
The role of the Liver: Nighttime regeneration and skin detox
According to TCM the Liver stores the blood and governs the smooth flow of qi. Based on the Chinese body clock, the Liver is most active between 1-3 am. When sleep is deep during this time blood is cleansed and replenished and toxins are processed, leaving the skin clear and more even. When sleep is disrupted the Liver qi stagnates and the liver blood becomes deficient leading to acne, breakouts, pigmentation, and redness. Hormonal acne, uneven skin tone, increased skin reactivity or flushing, and worse skin issues prior to menstruation are all signs of a potential Liver imbalance.
The Heart and the Spirit: Sleep quality shows on the face
The Heart governs the blood and houses the Shen/spirit. Good sleep reflects and calm and settled Shen. The the spirit is well-rested the eyes are bright, the complexion is radiant, and the facial expression is relaxed. Poor sleep reflects a restless Shen leading to dark circles, facial tension, and premature aging. If the Heart/Shen is disturbed or unsettled you might see dark or purplish under-eye circles, dull or scattered facial energy, and facial flushing from stress.
The Lung: Skin barrier and immunity
The lungs govern the skin and Wei qi. The Wei qi is a protective qi that circulates at the surface of our body to the protect us from external invasions of pathogens. It functions as part of our immune system and nervous system. During sleep, the lung qi restores the skins’s protective barrier. Recurrent poor sleep leads to weakening of the Lung qi that shows up on the skin as eczema, rashes, slowed wound healing, frequent skin infections, and increased sensitivity. In all inflammatory skin conditions, we find that chronic sleep deprivation makes symptoms even worse.
The Spleen: nourishment and glow
The Spleen transforms food into qi and blood which nourish the skin. In people who sleep late and eat late at night, the spleen function becomes impaired. When the Spleen is defieicnt the face can be puffy, the eyelids swollen, the complexion is yellowish, dull or pale, the skin sags or is loose, and puffy dark circles form.
