Just 15 minutes of meditation twice a day significantly reduced blood pressure in adolescents with high normal systolic pressure.
According to these data, stress plays an important role in the pathogenesis of hypertension and reduction of stress factors will normalize blood pressure (BP). Despite the fact that the subtle mechanisms of this phenomenon are unknown, Dr. Vernon Barnes et al (College of Medicine, GA, Augusta) said: "Being in a calm state reduces the levels of stress hormones such as cortisol, and reduces the activation of the sympathetic nervous system" . This decrease neurohumoral activity can reduce the workload on the heart and blood vessels, improve their function, lower blood pressure.
The authors randomly assigned students to teenagers of African-American descent or meditation classes (15 minutes twice a day for 4 months; n = 50), or a training program on healthy lifestyles, in accordance with the recommendations of the National Institutes of Health (15 minutes daily; n = 50). At baseline, 2 and 4 months from the beginning of the study and then after 4 months of observation was performed daily holter monitoring of blood pressure.
It turned out that by the end of the study in adolescents engaged in meditation, systolic and diastolic blood pressure was at 3.5 and 3.4 mm Hg. Art. lower than in the control group, where the levels of blood pressure have not changed. It is important that this positive trend persisted and after 4 months of observation, "said Dr. Barnes in the new issue of American Journal of Hypertension. According to the authors, meditation can be incorporated into a comprehensive program of prevention of hypertension in young people.
