have you ever felt your body and mind calm down after hugging your boyfriend? that’s a common response, according to a new study — if you’re a woman.
the research, published in
the journal plos one
, found that women’s stress levels decreased after they hugged a romantic partner, but that the same wasn’t true for men. the data is limited, though, given that the study was a small one and all the participants were cisgender and in straight relationships.
researchers from ruhr university bochum in bochum, germany focused on
cortisol
, the body’s main stress hormone, which controls mood, motivation and fear. they studied 76 people in couples, all between the ages of 19 and 32. (the study welcomed people of all sexual orientations, researchers say, but the couples who made it in were only people in straight, male-female relationships.)
all the couples were subject to a stress test that involved keeping their hands in ice-cold water for several minutes. a saliva sample was taken before and during the experiment to test for cortisol levels. after the stress test, half of the couples were told to hug for 20 seconds. the other — the control group — did not hug. the participants’ stress levels were tested again both 15 minutes and 25 minutes after the experiment. and no, they were not told what that hug should look like: “no specific instruction was given to allow for a natural experience of the embrace,” the study says.
