Sleep deprivation can have a negative impact on our physical appearance, particularly in the facial region. Puffy eyes, swollen skin, dark circles, and red eyes are all common indicators of a lack of sleep. This occurs due to fluid buildup under the eyes, caused by disrupted circulation and natural blood vessel constriction. The thin and delicate skin around the eyes, combined with the proximity of blood vessels to the surface, results in the noticeable discolouration and puffiness associated with under-eye bags. While genetics and lifestyle factors also play a role, achieving adequate sleep of 7-9 hours per night can significantly reduce the appearance of eye bags and improve overall skin health.

Fluid retention and blood vessel dilation cause discolouration and puffiness
Sleep deprivation can cause fluid retention and blood vessel dilation, resulting in discolouration and puffiness around the eyes.
The skin around the eyes is thinner than in other areas of the face, making it more susceptible to fluid retention, blood vessel dilation, and pigmentation issues. When you don't get enough sleep, the body struggles to regulate blood flow, reduce inflammation, or repair damaged skin cells. This can lead to increased blood flow in the eye area, causing discolouration. The thin skin around the eyes also has a weaker skin barrier, making it more prone to accelerated ageing, sagging, and eye puffiness.
When you don't get enough sleep, the oxygen levels in your eyes decrease, causing the blood vessels to dilate and giving you bloodshot eyes. As the blood vessels dilate, the volume of blood passing through them increases, and their proximity to the thin-skinned surface of the eye causes a noticeable dark tint. This process results in dark circles under the eyes.
Additionally, sleep helps regulate fluid levels in the body, including around the eyes. When you're sleep-deprived, the body struggles to maintain healthy fluid levels, leading to fluid accumulation in the delicate tissue under the eyes, resulting in puffiness and swelling. This fluid retention is a common symptom of sleep deprivation, and it can worsen the appearance of puffiness under the eyes.
It's important to note that while sleep plays a significant role, various factors contribute to under-eye bags, including lifestyle habits such as excessive screen time, stress, and substance use.

Genetics and natural ageing processes can make blood vessels more noticeable
Dark circles and under-eye bags are commonly associated with sleep deprivation. However, there are several other factors that can cause these cosmetic concerns, with genetics and natural ageing processes being significant contributors.
Genetics and heredity can play a role in the development of dark circles under the eyes. Studies have shown that dark circles may run in biological families. If your parents or siblings exhibit this trait, you are more likely to have or develop it as well. Individuals with a medium-dark skin tone are more likely to experience hereditary dark circles. Additionally, certain ethnic groups, such as those with indigenous American or Middle Eastern ancestry, may be more predisposed to this condition due to genetic factors.
The natural ageing process also influences the visibility of blood vessels under the eyes. As we age, the skin undergoes changes, losing its elasticity and becoming thinner. This reduction in skin thickness makes the underlying blood vessels more noticeable. The ageing process also involves a decrease in fat and collagen content, causing the skin to appear less full and plump, which can cast shadows around the eyes.
The thinning of the skin and the proximity of blood vessels to its surface contribute to the tinted appearance observed in dark circles. When oxygen levels in the eyes decrease due to sleep deprivation, blood vessels dilate, increasing blood flow to the area. As a result, the deoxygenated blood vessels become darker and more visible through the thin skin, leading to the characteristic dark tint associated with dark circles.
While genetics and ageing are significant factors, it is important to note that other lifestyle habits and environmental factors can also influence the formation of dark circles and under-eye bags. These factors include inadequate or excessive sleep, dehydration, prolonged screen usage, stress, substance use, allergies, and smoking.

Lifestyle factors like screen time, stress, and substance use contribute to dark circles
Dark circles and under-eye bags are often indicative of lifestyle factors such as screen time, stress, and substance use.
Screen Time
The blue light emitted by electronic devices such as televisions, laptops, computers, tablets, and mobile phones can damage skin cells, accelerate signs of ageing, and cause dark circles. Increased screen time can also cause digital eye strain, dry eyes, itchy eyes, headaches, and blurry vision. Browsing your phone before bed can delay your sleep cycle and disturb your natural circadian rhythm, negatively impacting your skin. Blue light tricks your skin into thinking it is still daytime, impairing the natural night-time repair process. Screen time also steals moisture from the skin, causing collagen breakdown, and the blue light exposure can lead to dark pigmentation under the eyes, making you look exhausted.
Stress
Stress can accentuate dark under-eye circles as blood is diverted away from the face and towards vital organs. Additionally, excessive emotional stress can cause the delicate capillaries around the eyes to rupture, resulting in blood leakage that darkens the area. Mental health conditions are often linked to insomnia, which causes dark under-eye circles and a dull, pasty complexion.
Substance Use
Substance use, particularly heroin addiction, can lead to what is commonly referred to as "heroin eyes," characterised by constricted pupils, redness, and dark circles. This is due to the direct pharmacological effects of the drug on the body's nervous and vascular systems, as well as broader lifestyle impacts associated with addiction, such as sleep deprivation, poor nutrition, and overall physical decline.

Poor sleep weakens the skin, making it more susceptible to the effects of gravity and ageing
Sleep is essential for the growth and renewal of multiple physiological systems, including the skin. When we sleep, our bodies go through three distinct stages that contribute to our overall well-being and aid in the nightly restoration of our skin.
Poor sleep weakens the skin's ability to repair and rejuvenate itself, making it more susceptible to the effects of gravity and ageing. This is because inadequate sleep disrupts the natural process of blood vessel constriction, leading to dilation and increased blood flow in the eye area, which causes discolouration and puffiness. The thin and delicate skin around the eyes has a weaker skin barrier, making it more prone to accelerated ageing, sagging, and eye puffiness.
Additionally, poor sleep quality is associated with increased signs of intrinsic ageing, diminished skin barrier function, and lower satisfaction with one's appearance. People with poor sleep quality tend to have a higher BMI, which may contribute to skin ageing. Sleep-deprived individuals may also experience an increase in fine lines, uneven pigmentation, and reduced skin elasticity, making them appear older than their years.
The impact of poor sleep on skin ageing is supported by solid scientific data, with studies showing that poor sleepers exhibit increased signs of skin ageing and a slower recovery from environmental stressors such as UV radiation. This highlights the importance of obtaining sufficient, quality sleep to maintain skin health and slow down the ageing process.

Eye-rubbing can tear capillaries, leading to discolouration and puffiness
Sleep deprivation can cause under-eye bags, swollen eyes, and darker circles. The skin under the eyes is thinner, and the blood vessels are closer to the surface. When you don't get enough sleep, your blood vessels dilate, increasing blood flow. The thin skin under the eyes makes the dark tint caused by the increased blood volume more noticeable, resulting in dark circles.
In addition to sleep deprivation, several factors can contribute to under-eye bags and discolouration. One of the main factors is eye-rubbing. The skin around the eyes is very thin and delicate, with a network of tiny capillaries supplying blood to the area. These capillaries are extremely fragile, and excessive rubbing or scratching can cause them to tear, leading to discolouration and puffiness.
When capillaries are broken or irritated, the skin under the eyes darkens noticeably. This is because the thin skin layer has a weaker barrier, making it more susceptible to accelerated ageing, sagging, and eye puffiness. Additionally, the natural ageing process causes the skin to lose elasticity, making blood vessels more visible. As a result, the skin appears less full and plump, and shadows form around the eyes.
Excessive eye-rubbing can be caused by various factors, including fatigue, itchiness, or a foreign object in the eye. It is important to address the underlying cause of eye-rubbing to prevent further damage to the delicate skin and capillaries around the eyes. This may involve treating allergies or skin conditions, improving sleep habits, or simply being more mindful of the tendency to rub the eyes.
To summarise, while sleep deprivation can contribute to under-eye bags and discolouration, eye-rubbing can exacerbate the problem by tearing the fragile capillaries under the eyes, leading to discolouration and puffiness. Adequate sleep, gentle skincare, and addressing any underlying causes of eye-rubbing can help improve the appearance of under-eye bags and discolouration.

Frequently asked questions
When you don't get enough sleep, your body's circulatory system may not function optimally, leading to water retention in areas like under your eyes. The thin skin around the eyes can become puffy due to fluid buildup, and the increased blood flow in the area can cause discolouration, resulting in dark circles.
Dehydration, prolonged screen usage, stress, substance use, smoking, and genetic predispositions can all contribute to the development of dark circles and puffy under-eye bags. Rubbing your eyes can also irritate the thin skin and cause oedema.
Getting 7 to 9 hours of good quality sleep each night can help reduce puffiness and dark circles by improving circulation and reducing fluid buildup. Additionally, lifestyle changes, such as reducing salt intake before bed, using a cold compress, and increasing pillow support, can also help improve the appearance of under-eye bags.
