A French study carried out in 2007 found that 8 sessions of hypnosis treatment was effective in reducing blood pressure in the short, middle and long term. However there was no relationship between the practice of self-hypnosis and the evolution of blood pressure.
A group in Taiwan carried out a randomized controlled study of a biofeedback program to reduce blood pressure in patients with mild hypertension. Patients were trained to self regulate their blood pressure with continuous feedback signals of their level of blood pressure. The control group were told to manipulate their blood pressure without having any feedback signals. Results showed that the decreases in systolic and mean blood pressure were greater in the biofeedback group than controls. The team concludes that biofeedback exerts a specific treatment effect in reducing blood pressure in individuals with mild hypertension.
Yoga / Relaxation /Qigong / Meditation
An Indian study showed that after practicing 2:1 breathing for 3 months there was statistically significant change of the measured parameters compared to before treatment. There was clear reduction in systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, galvanic skin response and an increase in finger tip temperature, and they concluded that it is effective for managing hypertension.
Hawaiian traditional medicine
SITH (Self I-Dentity through Ho’oponopono) is a step-by-step problem-solving process that aims to promote peace, balance, and a new meaning of life and has its roots in ancient Hawaiian tradition A 2011 study evaluated the use of SITH in pre hypertension and hypertension patients. Blood pressure was measured up to 9 times at separate weekly visits and were analyzed on three occasions. Participants experienced sustained reductions in systolic blood pressure and diastolic blood pressure, with the 2-month post-intervention reductions exceeding the 1-month post-intervention reductions The effect was similar to that of published studies on exercise treatment for hypertension.
The most recent publication that Patient QI found was carried out by a Chinese group in Aug 2013. The group assessed the current clinical evidence of Tai Chi as a treatment for essential hypertension. They concluded that there was some encouraging evidence of Tai Chi as a treatment for hypertension but that generally the quality of the study methods was not good and a better trial should be designed to confirm the evidence.
