Go ahead and joke about getting your ‘beauty sleep’, but guess what? It turns out that sleep quality and healthy, youthful skin are deeply linked.
Most of us have experienced that awful moment when we look in the mirror after a late night and see puffy eyes and dry, lacklustre skin staring back at us. It’s easy enough to bounce back from these occasional indulgences, but chronic lack of sleep can play a major role in ageing your skin prematurely – in extreme cases leaving you looking a decade older.
When you don’t get enough sleep, lots of chemical changes take place that affect your skin health.
Numerous studies have shown that chronic sleep debt can dramatically impair skin function and integrity and may in particular affect collagen production. Collagen is the ‘scaffolding of the skin (and other body tissues), helping to maintain its firmness. It also protects against UV damage and bacterial infection, seals in moisture, improves elasticity and preserves its youthful, healthy appearance.
Sleep loss also causes the body to release too little human growth hormone. When we’re young, we need human growth hormone to help us grow. But as we age, it helps increase muscle mass, thicken skin and strengthen bones.
But it’s not just premature ageing that can result from sleep debt. Studies in animals have found that prolonged sleep deprivation causes them to develop ulcerous lesions on their legs and suffer increased risk of bacterial invasion through the skin owing to a breakdown in skin membrane integrity.
Sleep debt takes its toll
In humans, sleep debt and stress can trigger inflammatory skin conditions such as eczema and psoriasis. It can also exacerbate both atopic dermatitis and irritant contact dermatitis – so much so that over the past two decades a new medical speciality has emerged called psychodermatology.
The field of psychodermatology grew out of a number of published studies showing a link between mood and sleep problems in chronic skin diseases which may be why many skin conditions an sometimes respond well to antidepressants and anti-anxiety medications.
Scientists attribute the link between chronic insomnia and skin disorders to the immune-altering effects induced by the release of excess glucocorticoids triggered by sleep debt and stress.
This class of hormones regulates the metabolism of glucose. Every cell in the human body possesses receptors for glucocorticoids, which play a crucial role in immune function. Excess glucocorticoid production has been shown to negatively affect nearly every tissue in the body and accelerate the ageing process.
A night-time balancing act
Cortisol is arguable the most important of the glucocorticoids and there is evidence that your body releases more of this ‘stress hormone’ when it is sleep deprived. In excess amounts, cortisol can break down skin collagen, the protein that keeps skin smooth and elastic.
We now know that formation of collagen is highly dependent on a sequence of biochemical events that take place during restful nights of sleep.
This night-time balancing act is disrupted in the presence of excess glucocorticoids (cortisol in particular).
Chronic sleep deprivation has been shown to damage immune function. Of particular significance for skin health are the lower levels of interleukin-1 (IL-1) commonly found in insomnia sufferers.
At normal levels, IL-1 triggers increased white blood cell production in response to foreign invaders and has a role to play in the production of collagen.
Get your beauty sleep
To keep your skin healthy and youthful-looking skin, most experts recommend you get at least 7 to 8 hours of restful sleep each night. In today’s hectic, stressed-out world, can be a tall order.
Women, in particular, are at risk from sleep disorders and in according to to successful women Arianna Huffington, publisher of The Huffington Post, and Cindi Leive, publisher of Glamour – sleep deprivation is one of the most crucial issues today’s women face. The resulting exhaustion, they say is undermining women’s creativity, judgement, and relationships. In addition it is damaging to health leading to greater risk of heart cardiovascular disease weight gain and depression.
It’s not just how many hours we sleep but the quality of the sleep we get that matters. In recent years, repeated studies have found that while women average 8 to 13 more minutes of sleep per night than men, the quality of women’s sleep is much poorer.
Why do women have more interrupted sleep than men? Health experts say biological and sociological factors are both to blame.
It’s different for girls
Research by the National Sleep Foundation in the US indicates physical processes unique to women often result in sleep deprivation.
During menstruation, around 15% of women report difficulty sleeping due to tender breasts , headaches and cramps. During pregnancy, nearly 80% of women have sleep problems. During menopause, 40% report interrupted sleep, most frequently due to hot flashes.
According to Joyce Walsleben, associate professor at the New York University Sleep Disorders Center, author of A Woman’s Guide to Sleep, and a spokeswoman for the National Sleep Foundation “In many of these cases, the problem is tied to hormonal fluctuations.
Essential oils to help you sleep
You don’t need to turn to sleeping pills to get the sleep you need. There are lots of less drastic things you can do to get a better night’s sleep (see our article How to get a good night’s sleep).
