Crying does not alleviate acute pain perception: Evidence from an experimental study.

Despite previous findings on pain alleviating effects of emotional expression and the widespread idea about the generally beneficial consequences of emotional crying, research on the possible pain alleviating effects of crying is largely missing. Two quasi-experimental studies demonstrated that crying induced in laboratory conditions does not alleviate acute pain responses, suggesting that role of crying in pain interventions is doubtful. Less directly, results cast light on the role of emotional distraction from acute pain and possible crying-related neurochemical changes.
