Sleep and Our Skin
Sleep has a powerful and direct effect on skin health—often more than any skincare product or procedure alone. The effects of poor sleep are seen on a systemic level as well as a superficial level. When we are chronically under slept, we feel it in ours bodies and we see it on our skin. From a Chinese Medicine perspective, sleep is essential for nourishing the Blood, Yin, and Shen (spirit)—all of which directly influence skin health. In TCM the skin is not viewed in isolation; it reflects the state of the internal organs, the flow of qi, and harmony of the whole system.
When our bodies sleep, our DNA is repaired, toxins are cleansed from the blood, cells heal and regenerate, and new building blocks like collagen and elastin are formed. From a TCM perspective, sleep nourishes the blood and yin. If our blood and yin are weak, our appearance is dull and pale, our skin becomes dry, thin, lackluster, and prematurely aged. It is no surprise that when we feel well-rested we look our best.
According to Chinese Medicine, the Liver stores the blood and governs the smooth flow of qi and blood throughout the body. It is responsible for cleaning and replenishing the blood and processing toxins, as well as helping to build new blood resources. Based on the TCM body clock, the Liver is most active during the hours of 1-3am when we should be deep asleep. Disruptions in sleep that keep us awake during these hours can lead to more stagnation, heat, and deficiency which can look like breakouts, acne, redness, pigmentation issues, dullness, dryness and sensitivity.
Sleep disruptions and the Organs: Inadequate or interrupted sleep can produce imbalances in our organ systems that show up on the skin. Looking at the skin can tell us what organ is out of balance and how we might support better sleep and overall health.
Heart: Signs of imbalance - restlessness, flushing, dull eyes and complexion, dark purplish circles under the eyes. Support your Heart by giving yourself 1-2 hours of time to unwind before bed. No screens, keep the lights low, engage in activities that bring you joy and dont activate the emotions strongly, write in a journal, meditate, read.
Spleen: Signs of imbalance - puffy face or eyelids, yellowish dull complexion, swollen dark circles under eyes, sagging loose skin. Help your Spleen by not eating too close to bedtime. Avoid indulging in sweets in the evening, especially avoid cold sweet foods, which can bog down the digestion and the spleens ability to process. Wake up by 7-9am to avoid depleting the Spleen further. Opt for going to bed earlier rather than sleeping in.
Liver: Signs of imbalance - acne, breakouts, hormonal imbalances, pigmentation issues, and reactive skin. Aim for being asleep by 10:30pm at the latest. Keep regular bedtime routines. Make sure that movement and exercise are part of your daily routine. Reduce stress as much as possible.
Lungs: Signs of imbalance - eczema, rashes, poor healing of wounds, increased sensitivity, dry skin, flaking. Protect the lungs by using a humidifier in the winter if your home is very dry, avoid sleeping directly near a heat source, avoid sleeping in front of a fan or open window.
Kidneys: Signs of imbalance - sunken appearance to face, dark under eye circles, overall lack of vitality. Keep your feet warm at night with socks and slippers (dont walk barefoot). Soak your feet in hot water for 15-20min before bedtime. Keep your sleeping space dark and eliminate as much light as possible with blackout curtains, unplug any electronics that have visible light in your bedroom and leave phones and other devices in another room to charge.
Western Medicine agrees that quality sleep is essential for good skin health.
When you sleep, especially during deep sleep or slow-wave sleep, your body increases the rate of cell regeneration, DNA repair, and collagen production. This is when skin repairs daily damage from UV exposure, pollution, and inflammation. Poor sleep = slower healing and accelerated aging.
Sleep deprivation raises cortisol levels, a stress hormone that breaks down collagen, weakens the skin barrier, and increases inflammation. Over time elevated cortisol leads to more fine line and wrinkles, loss of firmness and elasticity, and sagging skin. Even one week of shortened sleep has been shown to reduce skin elasticity and hydration. During quality sleep, skin barrier function improves and transepidermal water loss decreases, and when sleep is poor your skin barrier becomes “leaky”, increasing water loss, increasing sensitivtiy, redness, and irritation. This is why tired skin often feels tight and dry or looks flaky.
Lack of sleep also increases systemic inflammation and disrupts hormone balance. Increases in cortisol lead to more oil production on the skin and slower immune response, which create an environment where bacteria thrive. This is how we see poor sleep contribute to acne, rosacea, eczema, and psoriasis. Breaktouts after late nights are not a coincidence—they’re hormonal and inflammatory.
Poor sleep affects circulation and lymphatic drainage. Blood pools under the thin skin around the eyes creating dark circles, and fluid retention creates puffiness. Chronic sleep deprivation can make dark circles permanent due to collagen thinning in the under-eye area. Well-rested skin has better blood flow, and healthy circulation delivers oxygen and nutrients to the face to nourish the tissues creating a brighter complexion, more even skin tone, and a natural glow.
Melatonin is the skin’s antioxidant hormone. Released at night, melatonin is a powerful antioxidant that protects the skin from oxidative stress, helps regulate skin pigmentation, and supports anti-aging processes. Staying up late and being exposed to blue light (phones! computer screens!) suppress melatonin causing the skin to age faster.
How to optimize your sleep for healthier skin
Aim for 7-9 hours of quality sleep nightly, more if your body needs it! Don’t skimp on sleep, we need more than we think we do.
Keep a consistent sleep schedule, even on the weekends.
Keep your bedroom dark and cool, this supports melatonin production.
Avoid screens for at least 60 minutes before bedtime. Keep screens out of your sleeping area!
Your skin absorbs better at night, so use your best quality skincare products before bed.
Use silk or cotton pillowcases, and wash them regularly (at minimum every 2-3 days, more if acne-prone or pets sleep in the bed), silk helps to reduce friction and decrease bacteria on the pillow.
