痛苦耐受力（DT）较低的人会感到负面情绪特别具有威胁性，并且非常有动力减少或避免此类情感体验。因此，这些人难以调节情绪，并倾向于采取适应不良的策略，例如暴饮暴食，作为减少或避免痛苦的手段。哈他瑜伽鼓励人们在面对身体和心理不适时实施以当下为中心的意识和不反应，因此，成为增加 DT 的一种潜在策略。为了测试哈他瑜伽干预是否可以增强 DT（跨诊断风险和维持因素），本研究随机分配因压力而情绪化饮食较高的女性 (N = 52) 接受为期 8 周、每周两次的哈他 (Bikram) 瑜伽干预或等待名单控制条件。在基线、治疗期间每周和治疗后 1 周测量自我报告的 DT 和情绪化饮食。与预测一致，瑜伽条件下的参与者报告称，在干预过程中，相对于候补参与者，DT 增加更大（Cohen 的 d = 0.82）。同样与预测一致的是，瑜伽条件下情绪化饮食的减少比候补条件下更大（科恩的 d = 0.92）。重要的是，痛苦吸收的减少（DT 的一个特定子方面）导致情绪化饮食差异的 15%，情绪化饮食是饮食病理学的标志性行为和肥胖的危险因素。
Individuals with low distress tolerance (DT) experience negative emotion as particularly threatening and are highly motivated to reduce or avoid such affective experiences. Consequently, these individuals have difficulty regulating emotions and tend to engage in maladaptive strategies, such as overeating, as a means to reduce or avoid distress. Hatha yoga encourages one to implement present-centered awareness and non-reaction in the face of physical and psychological discomfort and, thus, emerges as a potential strategy for increasing DT. To test whether a hatha yoga intervention can enhance DT, a transdiagnostic risk and maintenance factor, this study randomly assigned females high in emotional eating in response to stress (N = 52) either to an 8-week, twice-weekly hatha (Bikram) yoga intervention or to a waitlist control condition. Self-reported DT and emotional eating were measured at baseline, weekly during treatment, and 1-week post-treatment. Consistent with prediction, participants in the yoga condition reported greater increases in DT over the course of the intervention relative to waitlist participants (Cohen’s d = .82). Also consistent with prediction, the reduction in emotional eating was greater for the yoga condition than the waitlist condition (Cohen’s d = .92). Importantly, reductions distress absorption, a specific sub-facet of DT, accounted for 15% of the variance in emotional eating, a hallmark behavior of eating pathology and risk factor for obesity.
