Beauty Sleep Is A Must. Let’s Understand Why?

New research proves that there’s such a thing as “beauty sleep,” after finding that just 2 nights of poor sleep can make one appear less attractive and healthy to others.

Researchers say that just 2 nights of sleep deprivation can make one appear less attractive. Furthermore, researchers found that reduced attractiveness caused by lack of sleep may impact an individual’s social life; people could also be less willing to socialize with individuals who fail to urge enough shuteye.

We all know that sleep is important for our health and well-being. Not only is it important for memory consolidation, but our bodies also need sleep so as to revive and rejuvenate.

However, statistics show that around 1 in 3 adults within the us fail to urge the recommended minimum of seven hours of sleep each night.

Unsurprisingly, insufficient sleep can take its toll on our appearance, with puffy eyes and a dull complexion being two of the tell-tale signs of a nasty night’s slumber – and, consistent with the new study, these effects don’t go unnoticed by others.

Sleep-deprived adults rated as less attractive and healthy
Sundelin and colleagues enrolled 25 healthy men and ladies to their study.

Each participant was required to sleep for 8 hours on 2 consecutive nights. One week later, subjects were asked to limit their sleep to only 4 hours on 2 consecutive nights.

After both sleep conditions, participants visited a laboratory to possess their photograph taken. For the images , subjects were instructed to not wear makeup, to wear their hair pulled faraway from their faces, and to wear a gray t-shirt.

Next, the researchers recruited 122 adults – mentioned as “raters” – and asked them view each photograph. The adults were asked to rate how attractive, healthy, or trustworthy they perceived the person in each photograph to be, also as whether or not they would really like to socialize thereupon person.

Not only were participants rated as less attractive and healthy following sleep restriction than once they were well rested, but the raters also reported a reduced willingness to socialize with adults who looked sleep-deprived.

Ratings of trustworthiness didn’t appear to be suffering from sleep duration, the team reports.

Findings could also be explained by effects of sleep on blood flow to the skin
Sundelin and colleagues speculate that the effect of sleep deprivation on skin blood coloration may partly explain why poorly rested adults were rated less attractive and healthy.

“A healthy, attractive face is characterized by a particular degree of redness, which successively is indicative of increased vasodilation and vascularization,” they write.

“Blood flow to the skin is strongly promoted by sleep and this vasodilation could also be how for the body to facilitate the distribution of endogenous defense agents. With a scarcity of sleep, blood flow to the skin is reduced, and consistent with raters faces look paler after not sleeping.”

While further studies are needed to realize a far better understanding of the mechanisms underlying the consequences of sleep deprivation on facial appearance, the researchers believe that their findings further highlight the importance of an honest night’s sleep.
