Why you need your beauty sleep
Using the sentence 'I need my beauty sleep' isn't bogus, as a lot happens to our skin as we get some shut eye.
Sonja Dymalovski, Skincare Expert at What Skin Needs, explains how the term came about and what goes on in our bodies when we're resting.
"There is a reason why we call a long and deep sleep the ’beauty’ sleep. Our skin cells break down proteins faster when we are asleep, which means they regenerate itself and repair any damage caused by stress, pollution and lifestyle during the day," she told Cover Media. "Sleep not only reduces the ’stress’ hormone (cortisol), which can cause stretch marks, discoloration and breaks out, but it also increases the ’sleep’ hormone (melatonin), which protects us from free radicals that cause fine lines and dark spots."
This is why it's important to remove make-up and moisturise your face before you go to bed, she stresses. Nourishment helps your skin get ready for the overnight process and by using natural ingredients your pores will be able to breathe throughout the night.
Dr Virginia Hubbard, Consultant Dermatologist at London Bridge Hospital, highlighted what happens to skin when you don't get enough sleep.
"Some inflammatory skin conditions are worse if a person is sleep-deprived, such as eczema and psoriasis, as sleep allows the inflammatory mediators to drop," she says. "Unfortunately, this lack of sleep can often lead to a vicious cycle, as if a person has itchy skin from eczema, this may make it difficult to sleep, and so the problem gets worse. Acne breakouts can also be worse if sleep is disturbed, as high cortisol levels contribute to spots."
She also warns wrinkles and fine lines will be clearer with less sleep - not a great look.
On top of how much sleep you get, Dr Hubbard says the quality affects your skin. The non-REM sleep is the best for cells in the body to repair, as there's less energy sent to the brain and more to the skin.
Like Sonja, she notes ingredients in night creams are important and suggests niacinamide to even out pigmentation, provide excellent moisturising qualities and plump up fine lines.
