D'après une récente étude menée aux Etats-Unis, les injections de botox auraient un effet positif sur le moral et amélioreraient le bonheur de la personne "botoxée".
Comme quoi, le botox n'est pas seulement bon contre les rides!
Botox improves happiness, says new study: injections stop frowns and trick brain into feeling better
Can't figure out how to turn your frown upside down?
Scientists say Botox could help cheer you up, not just by erasing wrinkles but by tricking your brain into making you feel happier, too.
A new study by the US Association for Psychological Science has found that the anti-wrinkle treatment, which works to smooth fine lines by paralyzing muscles in the face, actually has an effect on the brain as well, reports London’s Telegraph.
40 volunteers in the study, done by researchers from the University of Wisconsin, were evaluated both before and after having Botox injections. Their response time was recorded as they read a series of statements out loud, with content ranging from "angry" to "sad" to "happy."
The study found that the subjects took longer to read the more "negative" passages after the injections than before. Researcher David Havas told the Telegraph this delay was small but critical because it implies that the brain was processing the negative emotion more slowly after the drug's injection.
"Normally, the brain would be sending signals to the periphery to frown, and the extent of the frown would be sent back to the brain," explained research leader Professor Arthur Glenberg. "But here, that loop is disrupted, and the intensity of the emotion and of our ability to understand it when embodied in language is disrupted."
In other words, when your face stops frowning, your brain gets the message that you've decided there's less to frown about.
"There is a long-standing idea in psychology called the facial feedback hypothesis," Havas told the Telegraph, who believes the new study shows that, "When you're not frowning, the world seems less angry and less sad."
So does this mean celebrities like Kim Kardashian, who have openly admitted to getting Botox, not only have smoother faces than their Botox-free friends but are happier too?
Not necessarily. A study published earlier this year in the Journal of Cosmetic Dermatology found that when injections of Botox are used to paralyze some facial muscles, other nearby muscles have to work overtime to compensate, creating even more lines in the face.
