Every day we spend hours in front of the mirror doing skincare, applying multiple beauty products just to get that perfect glowing skin. But what if we told you that sleeping is the secret to the glowing skin you always wanted?

As cliche as it might sound, beauty sleep is a real thing. If you have ever noticed dark circles or patchy/pale skin after inadequate sleep, you know that sleep affects how your skin looks. Just like poor, disturbed sleep makes your skin dull, a good night's sleep makes your skin glow.

In this blog, we will see the science behind the concept of beauty sleep and how you can improve your sleep quality to wake up with healthier skin.

Sleeping Beauty – The Science Behind Beauty Sleep

What is beauty sleep?

We all know how important sleep is to restore energy and function effectively in our daily lives. However, that's not all; sleep also helps in many other things, and waking up prettier is one of them.

When we sleep, our body produces Growth Hormones and Melatonin (sleep hormone), which makes it go into repair mode. Thus, we feel refreshed and rejuvenated after a good sleep. Hence, the phenomenon of beauty sleep is not just a fluke; it's, in fact, science.

Beauty sleep benefits - The science behind beauty rest

Our skin is subject to a lot of things during the day; all the dust in the environment and other pollutants damage the skin and make it rough. However, certain physiological activities during sleep help undo the damage done during the day.

  • Growth hormone

When you sleep, the body releases growth hormone (GH). This growth hormone stimulates the synthesis of collagen. Collagen is a protein found in the skin, and new collagen makes your skin look youthful. Therefore, GH helps develop, maintain, and repair the skin.

  • Reduced cortisol

The production of cortisol, the stress hormone, declines during the onset of sleep. So sleep helps maintain homeostasis in the levels of cortisol present in the body. If you don't get enough sleep, an increased level of cortisol may cause acne, breakouts, dryness, wrinkles, premature aging, etc.

  • Melatonin production

Melatonin is the sleep hormone responsible for regulating your circadian rhythm. However, it also acts as an antioxidant, which helps protect the skin. The production of melatonin increases when we sleep during the night; therefore, melatonin also plays a significant role in sleep, affecting your skin.

Effects of sleep on skin

Sleep affects various physiological processes in your body. These physiological processes, in turn, affect other things in the body. The following section talks about how sleep can have a significant impact on your skin.

What are the benefits of a good night's sleep?

A healthy amount of sleep is good for your mental as well as physical health. We all know how good it feels to have a long, sound sleep on the weekend. However, that's not it; a good amount of sleep also does wonders for your skin.

Blood flow in the skin increases during sleep, giving it a more glowing and flushed look on waking up. On the other hand, if one doesn't get enough sleep, it may cause an accumulation of blood in certain areas, like under the eyes, etc., causing dark circles and under-eye bags.


We know that there is a production of growth hormones in the body during sleep. This growth hormone is involved in collagen synthesis, and collagen is a constituent of skin. Collagen prevents your skin from sagging, keeps it firm, and prevents sleep wrinkles.


Studies have shown that your sleep quality significantly affects your mood. Getting good sleep will affect your mood positively, and you will wake up feeling content and peaceful. Your mood and facial expression directly relate to each other, so it will show on your face if you're happy. Studies have also shown that happy people are perceived to be more attractive.

The increased blood flow during sleep helps our skin better utilize the skin-replenishing ingredients present in your beauty products. Moreover, since our skin doesn't have to fight UV rays or atmospheric dust during sleep, it can focus on healing itself and make use of the nourishment provided by beauty products.


If one doesn't get enough sleep, the blood flow in the skin may not be proper, leading to patchy, uneven skin tone. Therefore, adequate sleep is required for healthy blood flow in the skin and a healthy complexion.

What happens if you don't get a good night's sleep?

Since a good amount of sleep keeps you healthy, poor, disturbed sleep would do the exact opposite. You know its effects if you have pulled an all-nighter or slept for less than 4 hours for 2-3 nights. Dark circles, grumpy moods, burning eyes, etc., are all consequences of poor sleep quality.

When you are sleep-deprived, there is an increase in blood near the eyes. This skin near the eyes is very thin, which means that the blood vessels are closer to the surface. Therefore, when there is an increased volume of blood in the vessels, the dark color of the vessels reflects in the skin near the eye, which causes dark circles to appear.

The fluids from the vessels leak into the skin, and this leakage causes puffy eyes or under-eye bags, which is the swollen appearance of the under-eye area.

When we sleep, our body perspires and balances the hydration levels on the skin. Sleep deprivation, therefore, leads to dehydrated skin. It also leads to lower skin pH levels, making it look dull. Moreover, the rise in cortisol levels due to a lack of sleep breaks down the protein that makes your skin smooth, giving it a dull look.


Sleep deprivation leads to increased cortisol levels, which triggers inflammation. The increased cortisol levels make the skin more prone to acne and other skin conditions like rashes, eczema, etc. Not just that, once these skin conditions are triggered, they even take more time to heal if the poor sleep pattern continues.

Poor sleep takes a toll on one's mental health. The increased cortisol levels lead to stress, and your mood gets grumpy and irritable, and the corners of your mouth droop. We already know that smiling makes you look attractive, so a droopy face would do the exact opposite, making you look unattractive.

The Optimum amount of sleep required

We have mentioned 'good amount of sleep' and 'optimum amount of sleep' quite a few times now, but what exactly is the amount of sleep required to stay healthy and have glowing skin?

According to studies, adults require seven or more hours of sleep per night. But it's not just the quantity of sleep that matters; the quality of sleep also matters. If you get eight hours of sleep but the whole time you keep tossing and turning in bed, waking up in the middle, or don't go into a deep sleep, your body won't get the rest that it requires, which is why we need quality sleep of seven hours per night to wake up feeling beautiful.

How to get more beauty sleep?

Nowadays, quite a lot of people have a messed-up sleep cycle due to staying up late and watching screens in bed. Therefore, it's challenging to have a sleep schedule and adhere to it. However, since we know the importance of quality of sleep, not just to look more beautiful but also to stay mentally and physically healthy, we can try to have better sleeping habits.

Maintain a sleep schedule

Having a consistent sleep schedule, where you go to sleep and wake up at the same time every day, has many benefits. The circadian rhythm regulates the sleep-wake cycle, and sticking to a sleep schedule will make it easier for you to fall asleep on time because your body adjusts to sleeping at that particular time.

It might be difficult to go to sleep early if you're used to staying up late at night. However, to tackle this problem, you can start by sleeping 15-20 minutes earlier and continue until you reach a more preferred sleeping time.

Relax and prep up before sleep

Bedtime routines help your body relax and prepare itself for sleep. Your bedtime routine could be as simple as you want. It could be anything like reading a book, meditating, taking a warm bath, or maybe just brushing your teeth and washing your face. Sleep journaling can be great to get things off your mind and get a peaceful sleep.

We recommend having a simple nightly routine so that you don't laze off. Do something that you enjoy and that helps you relax. This relaxing nighttime routine helps you fall asleep easily.

Say no to blue lights

Blue lights emitting from your smartphone and laptop's screens interfere with your body's melatonin production, the hormone that signals that it's time to sleep. So if you use your devices later on in the night, it might trick your brain into thinking that it's still daytime.

Some things you can do to avoid blue light are wearing glasses that block it or downloading apps that block blue light on your smartphone. Although a bit hard, the best way is to not use your devices for at least one hour before bedtime.

Invest in a quality mattress

The mattress that you sleep on also affects the quality of your sleep. For example, if your mattress is worn out, it might cause backaches due to bad sleeping posture. In that case, you should either buy a new mattress or a mattress topper to give your body the comfort it needs for a good night's rest.

Keep your bedroom environment dark and cozy

The bedroom environment is also a determining factor in the quality of your sleep. The bedroom should be as dark as possible. If you can't fall asleep with the lights out, you can use fairy lights; they will give a little light and a warm, cozy feeling. Keeping plushies on the bed or anything that gives you a cozy feeling should help create a more pleasant bedroom environment. You can also play some sounds that help you get better quality sleep.

For the best experience, minimize the lights, external sounds, and blue lights in the bedroom. Also, keeping it clean and hygienic will help enhance the quality of your beauty sleep.

Other factors that affect your skin

  • Staying hydrated: Staying hydrated makes your skin look more fresh and soft. Drinking water helps maintain the moisture in the outer layer of the skin, preventing it from looking dull and dry. It also helps with skin repair.
  • Working out: Regular exercise and physical activity ensure better blood flow throughout the body. Blood carries oxygen and nutrients to cells; this helps nourish the skin and improve its physical appearance.
  • Nighttime skincare routine: A skincare routine is a must for your skin. If you want to wake up with healthy skin, you can use a mild cleanser and a night cream to ensure your skin is clean and moisturized throughout the night.
  • Type of beauty products used: Some beauty products might do more harm than good to your skin. For example, cheap beauty products have harsh chemicals that might make you feel that they are making your skin smooth and soft, but in the long run, they can prove to be very bad for your skin. 
  • Diet: They say you are what you eat; basically, food impacts your overall health. Healthy foods, like green veggies, fresh fruits, etc., will lead to healthy skin. Conversely, eating oily food, salty snacks, etc., will lead to more breakouts, wrinkles, and dull skin overall.
