The Effects of Humming-Bee Breath on Cardivascular Parameters
This linked study aimed to assess the immediate effects of Bhramari pranayama on resting cardiovascular parameters in healthy adolescents.
According to Yoga International, Bhramari pranayama (often called 'humming bee breath') is a safe and easy-to-learn practice that has tremendous therapeutic potential. Like other pranayamas, its power comes partly from its effects on the autonomic nervous system; lengthening the exhalation relative to the inhalation activates the calming parasympathetic branch of the nervous system. The practice has long been said to be able to quie...t the mind within a few breaths whilst the noise of bhramari’s buzzing can drown out mental noise and aid meditation.
This linked study aimed to assess the immediate effects of Bhramari pranayama on resting cardiovascular parameters in healthy adolescents. Sixty healthy adolescents of both sex were randomly divided into the Bhramari pranayama (Bhr.P) (n-30) and control (n-30) group. The Bhr.P group practiced Bhramari pranayama for 45 min (5 cycles) whilst the control group practiced normal breathing (12-16 breath /min). Heart rate was assessed and blood pressure recorded in a supine position after 5 minutes of rest.
Great findings! The heart rate decreased significantly in the pranayama group. Blood pressure indices, Pulse Pressure (PP), and Mean Arterial Pressure (MAP) significantly decreased after Bhr.p practice compared with controls. The authors concluded that Bhramari pranayama practice produces relaxed state and in this state parasympathetic activity overrides the sympathetic activity. It suggests that Bhramari pranayama improves the resting cardiovascular parameters in healthy adolescents. Super stuff :)
