Let’s talk about the science of getting a good night’s sleep

How many times have we heard folk saying, “I’m off to get my beauty sleep” as they wend their weary way to bed? Funnily enough, science backs up the notion that sleeping well has a beneficial effect on the way we look, as well as the way we feel.

Okay, it’s not rocket science that sleep is important for all of us. It would indeed be strange to spend around one-third of our lives sleeping for no good reason. However, the fact remains that we generally overlook exactly how important sleep is. So let’s take a look at some fundamentals.

Sleep is essential for the growth and renewal of multiple physiological systems in the body.

It is tightly controlled by the ‘circadian rhythm’, described by the National Institute of General Medical Sciences as: “physical, mental and behavioural changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in [our] environment.”

Circadian rhythm is regulated by how long we have been awake and the changes between light and dark. At night, our body responds to the loss of daylight by producing melatonin, a hormone that actually helps our body prepare for sleep.

Once we’ve fallen asleep, we begin a series of sleep cycles that continue through the night. Each cycle lasts some 90-120 minutes, so that if we sleep for 8 hours during the night we experience 5 cycles.

Each cycle is itself made up of 3 or 4 ‘non-REM’ stages and ends with a REM stage. (REM stands for Rapid Eye Movement)

So where does ‘looking good’ come into this? The answer is that it’s all to do with the connection between sleep and our skin.


We think of our skin as our outer covering, but it’s an astonishing organ that performs a vital role in protecting our bodies from environmental assault and maintaining our physiological balance. The skin itself has its own circadian rhythm, which helps regulate the repair and growth cycles within skin cells.

During the REM phases of sleep that we experience during the night, skin regeneration and repair occur at their highest level. Skin cell regeneration just about doubles during the night as our body miraculously repairs the damage inflicted during the day. The majority of cell repair occurs during REM sleep, and the proliferation of new skin cells is greatest at midnight.

So… what do you think happens when we don’t get enough sleep? Well, what’s immediately apparent is that a poor night’s sleep shows up in our appearance, including such irksome effects as dark circles under the eyes and a dullish complexion. But there’s worse news. Low quality sleep can accelerate the signs of skin ageing – and even weaken our skin’s capacity to repair itself at night.

Getting our beauty sleep is truly vital

It’s not only the right quantity of sleep that’s crucial but also the right quality of sleep. If we achieve a sound night’s sleep, this allows our body to regenerate and repair itself efficiently, which means we can wake up refreshed and revitalised in the morning.

And now the plug.
