Got someone to hug? Go for it. UCLA neuroscientist Alex Korb, author of The Upward Spiral: Using Neuroscience to Reverse the Course of Depression, One Small Change at a Time, says “A hug, especially a long one, releases a neurotransmitter and hormone oxytocin, which reduces the reactivity of the amygdala.”
Hand holding, pats on the back, and handshakes work, too. Korb cites a study in which subjects whose hands were held by their partners experienced a reduced level of anxiety while waiting for an expected electrical shock from researchers. “The brain showed reduced activation in both the anterior cingulate cortex and dorsolateral prefrontal cortex — that is, less activity in the pain and worrying circuits.”
And if you have no one handy to touch, guess what? Massage has also been shown to be an effective way to get your oxytocin flowing, and it reduces stress hormones and increases your dopamine levels. Win win.
The value of touching shouldn’t be overlooked when you’re down. According to Korb: “In fact, as demonstrated in an fMRI experiment, social exclusion activates the same circuitry as physical pain … at one point they stopped sharing, only throwing back and forth to each other, ignoring the participant. This small change was enough to elicit feelings of social exclusion, and it activated the anterior cingulate and insula, just like physical pain would.”
