**1. Introduction**

This chapter will explicate the physiological and psychological benefits of sweating, the ways in which group yoga beyond exercise and organized team sports creates bonding and community, and how, theoretically and practically, aspects of overall well-being are enhanced through group experiences of intense physical activity. The admonishment to hide our physiological discomfort when posed with adversity originates from a highly successful ad campaign by the Gillette Company to promote its antiperspirant *Dry Idea* in 1984 [2]. "Never let them see you sweat" became synonymous with success in a variety of fields as portrayed by the well-known celebrities who promoted the brand. Sweating publicly implied weakness, and has not been widely encouraged, until now. With the rise in popularity of group yoga and fitness classes, sweating in public is not only common, it is reported as pleasurable and leads to many physical benefits [4, 23]. Likewise, group experiences, specifically yoga, where demanding physical exertion is the primary activity create a sense of community and belonging that aligns with both health psychology and a biopsychosocial approach to well-being [15, 17]. How this happens is the purpose of this chapter.
