Last year, neuroeconomist Paul J. Zak, a professor at Claremont University (USA), conducted a series of studies taking blood samples from some subjects before and after using Facebook and Twitter. The analyzes showed that, after the use of social networks, the amount of oxytocin or "love hormone" increased , the same that we generate when we exchange caresses, kisses and hugs. In addition, the levels of stress hormones decreased after sharing tweets or exchanging messages on Facebook.
Among the conclusions of the study, Zak highlighted that people with higher levels of the aforementioned hormone are more generous and more likely to make donations.
