Hydration and Hot Yoga: Encouragement, Behaviors, and Outcomes

CONTEXT Currently, the literature on hot yoga is lacking, and there is still much to understand regarding the safety of these practices. However, one point of safety often emphasized is hydration during the practice of hot yoga. AIM The aim of this study was to examine hydration encouragement by hot yoga instructors and hydration behaviors and related outcomes by hot yoga participants. METHODS A cross-sectional study (n = 700) collected self-report data on demographics, types and frequency of yoga practiced, hydration behaviors, and self-report measures of adverse outcomes experienced by participants during hot yoga. Associations between hydration encouragement, protective behaviors, and adverse outcomes were analyzed through Chi-square tests. RESULTS Every protective hydration behavior was significantly associated with instructor encouragement (P < 0.05). Hydration before or during hot yoga participation was associated with a lower occurrence of dehydration symptoms (P < 0.05). CONCLUSIONS Hot yoga instructors hold a key role in encouraging hydration and student safety outcomes.
