Researchers who have combined the use of oxytocin nasal spray (versus placebo) with brain imaging have also learnt that oxytocin modulates the activity of your amygdala, the subcortical structure deep within your brain linked to emotional processing. Specifically, under the influence of a single blast of oxytocin nasal spray, the parts of your amygdala that tune in to threats are muted, whereas the parts that tune in to positive social opportunities are amplified. A single shot of oxytocin can help you glide through stressful social situations, like giving an impromptu speech or discussing a conflict-ridden topic with your spouse. If you were to face these difficulties under the influence of oxytocin, studies suggest, you’d have less cortisol, the so-called stress hormone, coursing through you, and you’d behave more positively, both verbally, by disclosing your feelings, and non-verbally, by making more eye contact and friendly gestures. Related research shows that behaving kindly in these ways also raises your naturally occurring levels of oxytocin, which in turn curbs stress-induced rises in heart rate and blood pressure, reduces feelings of depression, and increases your pain thresholds.
