Prehypertension is a condition defined by elevated blood pressure (systolic BP 120-139 and diastolic BP 80-89). It is commonly the forerunner to full blown high blood pressure, and also is the target of aggressive intervention.
In a randomized controlled test comparing yoga to way of living alteration (healthy diet plan, exercise etc.) and yoga plus way of living adjustment in grownups with prehypertension, participants in the yoga plus lifestyle group revealed substantial decreases in systolic high blood pressure (BP) as compared to the yoga exercise just team, which experienced a substantial decline in diastolic BP. This recommends that yoga exercise could add to way of living modifications focused on reducing cardio illness risk.

Considerably much more research has attended to the effects of yoga exercise interventions on hypertension (high BP). An organized evaluation of 17 randomized regulated trials found 11 researches that connected normal yoga exercise technique to considerably greater decreases in systolic BP compared with pharmacotherapy, breath understanding, health and wellness education, no treatment, or normal care. Alternatively, 5 research studies located that yoga exercise had no result on systolic BP compared to dietary alteration, enhanced typical care, relaxation or physical exercise.
