| Research Abstract |
Emotional laughter is highly relevant for social interaction, especially for social communication in human beings or animals. We verified the practical effectiveness of the "laughter" or "positive emotion" as coping to environmental stresses that cause serious and negative impacts on the daily lives. We conducted two different approaches of occupational stress workshop to evoke the positive emotion toward bank clerks or healthcare professionals, both of them are recognized to feel relatively high levels of occupational stress. One approach was a self-physical exercising to provoke laughter including the facial strained muscle stretch and breathing. The other was half-constructed encounter group to develop interpersonal relationships with the social laughter or smiling by building empathy with others. In this study, we found that both different approaches to evoke the positive emotions exhibited effectively to reduce the mental and physiological distresses of participants. In the animal model for studying the environmental stress, post-weaning social isolation of rodents considerably alters fear and anxiety behaviors and changes neuroendocrine functions. In the current study, we observed that the tickling treatment, which mimics tumble-and-play manner, could reduce restraint stress-induced reactions and modulate fear-related behavior of isolated adolescent rats.
