Verifying the effect of positive emotion on distresses

感情用事的笑与社会互动密切相关，尤其是与人类或动物的社会交流。我们验证了“笑”或“积极情绪”在应对对日常生活造成严重负面影响的环境压力时的实际有效性。我们对银行职员和医疗保健专业人员进行了两种不同的职业压力研讨会，以唤起他们的积极情绪，这两种职业压力都被认为是较高水平的职业压力。一种方法是通过面部肌肉拉伸和呼吸等自我锻炼来引发笑声。另一组是半建构的相遇组，通过与他人建立同理心，以社交笑声或微笑发展人际关系。在本研究中，我们发现两种唤起积极情绪的方法都能有效地减少参与者的心理和生理痛苦。在研究环境应激的动物模型中，断奶后社会隔离显著改变了啮齿动物的恐惧和焦虑行为，并改变了神经内分泌功能。在本研究中，我们观察到挠痒治疗，模仿翻滚和玩耍的方式，可以减少约束应激诱导的反应，调节孤立的青春期大鼠的恐惧相关行为。

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.
