UNFORTUNATELY, like a hangover, tired skin cannot be fixed with a decent portion of greasy chips and an energy drink.

Women’s Health notes that regular sex can grace one’s skin with a healthy glow – youthful and dewy (or is that just sweat?), no matter if it’s tired or hung over.

But for those of us who have jobs, a few hours of sex a day is not always exactly within our reach.

And the next best thing is sleep. Like basic human needs such as eating and breathing, this is one you don’t have to pencil into your diary.

A recent study found that people who sleep less are, in fact, seen as less attractive and less approachable.

Manrepeller reported on a survey: “Raters were less willing to socialise with a subject who was sleep-restricted.

Sleep-restricted subjects were also rated as less attractive, less healthy and more sleepy compared to their well-rested selves.”

People tend to find others who look ‘healthy’ more trustworthy and are thus more reluctant to socialise with someone who doesn’t look completely healthy, with the signs of sleep deprivation: puffy eyes with dark circles and dull skin. A bad night’s sleep could mean more fine lines and wrinkles, according to Manrepeller.

Dermatologist Dr Nomphelo Gantsho said: “Crying, allergies and lack of sleep are common causes of puffy eyes, as well as other conditions. Puffy eyes after sleeping can be caused by too much sodium in the diet, which causes water retention. And dark circles occur when inflammation settles down.”

Importantly, Manrepeller notes that “these symptoms have nothing to do with skin function or cell turnover.”

So the ‘beauty’ of the skin is, in fact, not really badly damaged or affected. But symptoms of sleep deprivation make us appear ‘less attractive’, and we are also seen as less trustworthy.
