When you stay up and don't sleep, your eyes tend to be dry and irritated, which leads to inflammation and swelling or puffiness in the eyes. This can make your eyes look older and your eyelids show more fine lines. Tired eyes are also prone to twitching due to muscle fatigue.”
Results show that the faces of sleep-deprived individuals were perceived as having more hanging eyelids, redder eyes, more swollen eyes and darker circles under the eyes. Sleep deprivation also was associated with paler skin, more wrinkles or fine lines, and more droopy corners of the mouth.
Skin Aging
As you grow older, the tissues and muscles by your eye area weaken, so they sag a bit, making you look a bit sleepy. As you mature, our skin's elasticity weakens. Fats and fluids in the eye area can accumulate in your lower eyelids, making them look plumper, and in turn, a lot puffier.
What Is Skin Fatigue? According to Travis, skin fatigue is mainly caused by a combination of lifestyle- and stress-related factors—like lack of sleep and exercise, smoking and unhealthy diet, to name a few—as well as environmental aggressors like pollution and sun exposure.
Bottom line: Interrupted nights don't give your body the restorative sleep it needs—and even brief wakenings will still disrupt natural sleep rhythm, says Sadeh. “Our study is the first to demonstrate seriously deleterious cognitive and emotional effects.”
One study found that sleeping 5.5 hours each night over a two-week period while on a calorie-restricted diet resulted in less fat loss when compared to sleeping 8.5 hours each night. But it also resulted a greater loss of fat-free mass (including muscle).
Despite these trends, the research mostly agrees that six hours of sleep is not enough for most adults. Experts recommend that most adults need at least seven hours of sleep every night.
Sleep deprivation is thus readily observable from a set of facial cues. It seems that many of the colloquial cues, such as droopy/hanging eyelids, red eyes, dark circles under the eyes, and pale skin, are indicative of both sleep deprivation and looking fatigued.
Research has proven that a good night's sleep makes you look healthier, happier, and–yes–more attractive. “Beauty Sleep” isn't just a silly cliché–it is backed up by solid evidence.
Without regular, quality sleep, many people begin to notice an increase in fine lines, uneven pigmentation and reduced elasticity in their skin. Simply put, they look older than their actual years would indicate because lack of sleep weakens the skin's ability to repair and rejuvenate itself.
Anxiety is known to trigger production of the stress hormone cortisol. This changes your skin pores and increases skin oil production. Pores become clogged by the oil, bacteria festers and acne begins to form.
Stress causes changes to the proteins in your skin and reduces its elasticity. This loss of elasticity can contribute to wrinkle formation. Stress may also lead to repeated furrowing of your brow that may also contribute to the formation of wrinkles.
Stress plays a critical role in this phenomenon: High cortisol levels make individuals appear less fertile, thereby reducing their attractiveness. This makes sense, says the study's lead researcher, Markus Rantala. Stress inhibits sex hormones, and sex hormones influence physical attractiveness.
National Sleep Foundation guidelines. See Full Reference advise that healthy adults need between 7 and 9 hours of sleep per night. Babies, young children, and teens need even more sleep to enable their growth and development. People over 65 should also get 7 to 8 hours per night.
A sleep-deprived, tired-looking face, with dark circles under the eyes and swollen eyelids [4], is perceived as less attractive and less healthy [5].
Sleeping naked has a slew of health benefits, including helping you to lose weight. A study conducted by the US National Institutes of Health found that keeping yourself cool while you sleep speeds the body's metabolism because your body creates more brown fat to keep you warm.
