Yet six weeks later, when Zak shares the results with me, my blood tells a more dramatic story. In those 10 minutes between blood batches one and two, my oxytocin levels spiked 13.2%. That's equivalent to the hormonal spike experienced by the groom at the wedding Zak attended. Meanwhile, stress hormones cortisol and ACTH went down 10.8% and 14.9%, respectively. Zak explains that the results are linked, that the release of oxytocin I experienced while tweeting reduced my stress hormones. If that's the case, says Zak, social networking might reduce cardiovascular risks, like heart attack and stroke, associated with lack of social support. But there's even more to our findings. "Your brain interpreted tweeting as if you were directly interacting with people you cared about or had empathy for," Zak says. "E-connection is processed in the brain like an in-person connection."
