Effect of a yoga and naturopathy-based lifestyle intervention with nine-month follow-up on heart rate variability in patients with hypertension: A randomized controlled trial

Hypertension is associated with autonomic nervous system (ANS) dysregulation. Heart rate variability (HRV) monitoring is frequently used as a gauge of the ANS balance. The aim of the present study was to assess the effects of yoga and naturopathy on the autonomic variables in patients with hypertension. 262 hypertensive patients were randomly allocated to the study group (SG) or control group (CG) in a randomized controlled trial. For ten days, the SG (n = 131) group got received naturopathic treatments and yoga, whereas the CG (n = 131) group did not. HRV which was examined at the beginning and end of the 10-day intervention period and again after 9 months, served as the study's main endpoint. There was a significant change in the frequency domain of heart rate variability with a significant increase in High frequency (HF) and a significant decrease in low frequency (LF) and LF/HF (all p
