They shape who we are and who we are yet to be. They soothe our tumultuous inner world, fill the emotional gaps in our marriage, and help us remember who we really are.
By the way, they may do even more. Scientists now suspect that hanging out with our friends can actually counteract the kind of stomach-quivering stress most of us experience on a daily basis. A landmark UCLA study suggests that women respond to stress with a cascade of brain chemicals that cause us to make and maintain friendships with other women. It's a stunning find that has turned five decades of stress research - most of it on men- upside down.
Oxytocin, a "convivial" hormone
Until this study was published, scientists generally believed that when people experience stress, they trigger a hormonal cascade that revs the body to either stand and fight or flee as fast as possible, explains Laura Cousin Klein, Ph.D., now an Assistant Professor of Bio-behavioral Health at Penn State University and one of the study's authors. It's an ancient survival mechanism left over from the time we were chased across the planet by saber-toothed tigers.
Now the researchers suspect that women have a larger behavioral repertoire than just fight or flight ; in fact, says Dr. Klein, it seems that when the hormone oxytocin is released as part of the stress responses in a woman, it buffers the fight or flight response and encourages her to tend children and gather with other women instead. When she actually engages in this tending or befriending, studies suggest that more oxytocin is released, which further counters stress and produces a calming effect. (...)
