The primary goal of this R21 pilot grant is to obtain preliminary data on the efficacy of Integral Yoga for reducing self-reported menopausal hot flashes. Secondary aims are to determine the impact of yoga on objective hot flashes and other outcomes and study feasibility. Our primary hypothesis will be a greater reduction in subjective hot flash frequency and severity in the yoga group than in two control groups. Secondary outcomes will include a greater reduction in objective hot flash frequency; a greater decrease in hot flash interference; and greater improvement in sleep, other symptoms, mood, perceived stress, and overall quality of life in the yoga group.
