Chavasana in hypertension
In 1975, a prominent cardiologist Dr. Bombay Datey and his colleague Dr. Bhagat conducted a study of the impact of Shavasana on patients with hypertension. 86 patients, 68 men and 18 women aged from 22 to 64 years. Starting systolic pressure lies in the range from 160 to 270 mm Hg, and the initial diastolic pressure – from 90 to 145 mm Hg The average value of the pressure was 186/115 mm Hg These patients were divided into three groups: (1) – 15 people, did not receive any treatment except for placebo for a month before starting the Shavasana ; (2) – 45 as a result of reception of medicines reduce the pressure to near normal levels; most of them have taken the drug for more than two years and had a stable demand for drugs. Some have tried to reduce the dose of medication, resulting in increased pressure; (3) – 26 people who took drugs in various combinations, but did not reduce the pressure to a normal level.
Before the course Shavasana and during it at regular intervals were performed physical measurements, chest X-ray, ECG and removal of various blood tests. During shavasana patients studied phrenic slow rhythmic breathing with a short delay after each breath (1 sec) and the short delay after each exhalation (2 seconds). After the establishment of the rate they were asked to feel the coolness of the inhaled and exhaled air through the heat nostrils. This procedure was to save patients achieved a state of relaxation, but at the same time maintain mental focus and not let them fall asleep. Patients were also asked to feel the weight in different parts of the body for a more complete muscle relaxation. Savasana held to 30 minutes each day. Evaluation of patients are able to produce three, six, nine and twelve months. If after three months the patient has been no improvement, this technique is recognized as not suitable for him.
As a result, the practice Shavasana almost all patients there was a significant improvement, symptoms such as headache, dizziness, nervousness, irritability and sleep disorders, most patients have disappeared, while others have weakened. In all groups, there was an objective improvement in health status. In the first group, 9 people there was a significant reduction in blood pressure in 6 people have not seen. In the second group, where patients were able to control the pressure with medication, we decided to find out whether it is possible, by practicing Shavasana , reduce or discontinue medication intake. The need for medicines was reduced by one-third in 27 patients (60%); it was not possible to achieve this in 18 patients. In the third group, significant improvement occurred in 10 people; the state of the remaining 16 did not change. Thus, of the 86 patients in 46 (53%) Practice Shavasana caused improvement.
