What lack of sleep does to your looks and how to reverse the damage

We’ve all been there. Lack of sleep is the ‘gift’ that keeps on giving… That late-night work shift, a gripping box set, the baby who just won’t settle. While sacrificing sleep might feel necessary at the time, it’s not just your energy levels that suffer. A growing body of scientific evidence now recognises that skimping on those crucial hours of rest can have a surprisingly dramatic and decidedly unflattering impact on your appearance. It’s time to ditch the all-nighter if you want to keep that youthful glow and vibrant look.

In order to overcome a poor sleep routine, you have to first accept that a deep slumber is your body’s nightly repair and regeneration session. During this period, a cascade of vital processes takes place, including the release of growth hormones that help repair tissues and produce new cells. When you regularly ignore the importance of a good night’s sleep, you disrupt these essential functions - and your skin is often the first place to show the strain.

Late-night TV, unhealthy snacks and stress can cause lack of sleep.

Lack of sleep a leading cause of dark circles

One of the most noticeable effects of sleep deprivation is the dreaded dark circles under the eyes. While genetics play a role for some, lack of sleep exacerbates this issue. When you don't get enough rest, blood vessels under the delicate skin around your eyes can dilate, leading to a darker, bluish hue. Fluid can also accumulate in this area, contributing to puffiness and bags that cast shadows, making those circles appear even more pronounced.

The problem with dark circles and bags under the eyes is that they can be notoriously difficult to treat. However, getting proper sleep is the best starting point. 

Sleep deprivation is known to elevate levels of the stress hormone cortisol. Chronically high cortisol levels can break down collagen, the protein that provides your skin with its elasticity and firmness. This breakdown can lead to the development of fine lines, wrinkles and sagging skin, making you look older than you actually are. A 2010 study published in the journal Sleep found that chronic poor sleep quality was associated with increased signs of skin ageing and a reduced barrier function, meaning the skin was less able to protect itself from environmental stressors.

Dull skin a sign of sleep deprivation

It’s not just the under-eye area that bears the brunt of sleepless nights. A lack of sleep can also leave your complexion looking dull and pale. Why? When you’re tired, blood circulation is impaired, reducing the flow of oxygen and nutrients to your skin. This can result in a lackluster appearance and a loss of that healthy, rosy glow. It’s definitely a case of ‘goodbye radiance’!

Unfortunately, sleep deprivation can also contribute to breakouts. Stress hormones like cortisol can trigger inflammation in the body, which can exacerbate existing skin conditions like acne. Recognise that, when you’re tired, you might be less likely to stick to your regular skincare routine, further contributing to clogged pores and blemishes.

Hair scare: thinning and breakage

The effects of sleep deprivation aren't limited to your skin; your hair can also suffer. Just like skin cells, hair follicles rely on nutrients and hormonal balance for healthy growth. Chronic sleep loss can disrupt these processes, potentially leading to hair thinning and increased breakage. While more research is needed in this specific area, anecdotal evidence and a general understanding of the body’s stress response suggest a clear link.

You are more likely to notice hair loss if you are not sleeping well and are either going through the menopause or recently had a baby. Shedding hair can be traumatic and severely dent confidence, so making sure you get adequate rest is paramount.

Simple steps to overcome lack of sleep

The good news is that the aesthetic damage caused by lack of sleep isn't permanent, and making sleep a priority can have a significant positive impact on your appearance. Here are some simple tips to help you enjoy a proper night’s sleep:

• Establish a regular sleep schedule: Try to go to bed and wake up around the same time each day, even on weekends, to regulate your body's natural sleep-wake cycle. If you work shifts and find this difficult, get support from your GP. 

• Create a relaxing bedtime routine: Wind down before bed with activities like taking a warm bath, reading a book, or listening to calming music. Avoid screen time (phones, tablets, TVs) for at least an hour before sleep, as the blue light emitted can interfere with melatonin production, a hormone that regulates sleep. If you are still having trouble, consider listening to a sleep story - you will find a variety of options on both Alexa and Netflix.

• Optimise your sleep environment: Ensure your bedroom is dark, quiet, and cool. Invest in comfortable bedding and pillows. Ensure your bedding is washed regularly and use a fabric conditioner - it’s amazing how much a lightly scented duvet can calm the senses.

• Watch your diet and habits: Avoid caffeine and alcohol close to bedtime. Limit heavy meals in the evening. Regular exercise can improve sleep quality, but avoid intense workouts right before bed. Got a hobby or a passion project? Don’t burn the midnight oil trying to get something done; it can wait until the morning. 

• Prioritise sleep: Treat sleep as a non-negotiable part of your daily routine, just like eating and exercising.

• Never skip your skincare routine: A bedtime skincare ritual is a good way to wind down at the end of a busy day. Consider using a cleansing balm infused with calming botanicals, followed by a light foam or gel wash. Next, use a gentle toner before applying a soothing and hydrating serum, like hyaluronic acid. Finish with a good moisturiser or a few drops of facial oil. As well as providing that much-needed ‘downtime’ before bed, a regular skincare routine will help to counteract dark circles, puffiness, dull skin, and spots.
