BackgroundEvidence shows that yoga has several health benefits including the management of stress and possibly hypertension. The popularity of yoga is growing in the UK, but it is mostly unregulated with little information available about yoga providers and their sessions and students. This study aimed to explore who is providing yoga; what sessions are available, where and at what cost; and who attends these sessions in the UK. MethodsA web-based, anonymous, cross-sectional survey was undertaken, using Jisc Online Surveys, in March 3–Sept 3, 2020, among yoga providers in the UK. Participants were eligible if they were at least 18 years old and delivered a yoga session at least once in a fortnight during the past 6 months in the UK. Participants were approached through four major yoga associations in the UK. Findings407 yoga providers (335 teachers and 67 therapists) participated. Most providers were female (93%, n=379), White (93%, n=378), and aged 45–64 years (69%, n=280). Providers delivered a mean of 4·5 (SD 3·34) group sessions and 2·8 (2·58) one-to-one sessions per week, and the mean group size was 12·2 (7·94). 80% (n=326) of providers delivered evening sessions, and 25% (n=104) weekend sessions. The most common styles reported were Hatha (28%, n=172) and Iyengar (26%, n=162). Sessions had a varying emphasis on different yogic practices, but 59% (n=242) of providers allocated most time to yogic poses, 18% (n=72) to breathing practices, and 12% (n=50) to meditation and relaxation practices. Sessions were available in all the Office for National Statistics regions of the UK. The mean cost was £7·64 (SD £3·46) per group session and £39·71 (14·78) per one-to-one session. 73% (n=299) of providers reported that students disclosed their health conditions; the most common was mental health issues (41%, n=166) followed by hypertension (25%, n=103). 87% (n=356) of providers received training on hypertension and 46% (n=186) reported a need for further training. InterpretationTo the best of our knowledge, this is the first study in the UK providing information about yoga providers and their sessions and students. Yoga sessions are heterogeneous in the UK but there is more focus on yogic poses. People with hypertension attend these sessions, and there is a perceived need for more training on hypertension among providers.
