Yoga: intuition, preventive medicine, and treatment.

Mind-body fitness programs use a combination of muscular activity and mindful focus on awareness of the self, breath, and energy to promote health. The ancient discipline of yoga includes physical postures and breathing and meditation techniques. Scientific evidence exists about the physiologic effects of yoga. Mind-body fitness programs may offer therapeutic effects different from those offered by traditional body fitness programs.

Yoga for anxiety: a systematic review of the research evidence.

Between March and June 2004, a systematic review was carried out of the research evidence on the effectiveness of yoga for the treatment of anxiety and anxiety disorders. Eight studies were reviewed. They reported positive results, although there were many methodological inadequacies. Owing to the diversity of conditions treated and poor quality of most of the studies, it is not possible to say that yoga is effective in treating anxiety or anxiety disorders in general. However, there are encouraging results, particularly with obsessive compulsive disorder. Further well conducted research is necessary which may be most productive if focused on specific anxiety disorders.

Adjunct treatment with yoga in chronic severe airways obstruction.

Eleven patients with severe chronic airways obstruction were given training in yogic breathing exercises and postures. A matched group of 11 patients were given physiotherapy breathing exercises. Both groups of patients were followed up at monthly intervals for nine months with pulmonary function tests, tests of exercise tolerance, and inquiry into their symptoms. After training in yoga the mean maximum work increased significantly by 60.55 kpm; whereas no such rise occurred after training in physiotherapy. This objective improvement was associated with symptomatic improvement in a significantly higher number of patients given training in yoga.

Yoga as a preventive health care program for white and black elders: an exploratory study.

A ten-week yoga program was implemented with sixty-one white and forty-five low-income black elders at two community sites, along with a pretest-posttest control group research design with random assignment at each site. White elders attended class regularly, practiced yoga on their own on a daily basis, improved psychological well-being, and lowered their systolic blood pressure level, in comparison to a control group. Black elders, on the other hand, attended the once-a-week class regularly but did not practice on their own on a daily basis. Thus, they did not improve psychological well-being nor reduce blood pressure level in comparison to a control group. Social analysts suggest that low-income minority elders need more frequent contact with structured leadership in order to adhere to a daily routine that may lead to psychological and physical change. Other directions for controlled follow-up studies are suggested.

Effect of yoga-based and forced uninostril breathing on the autonomic nervous system.

Some reports have described the effects of forced uninostril breathing on autonomic activity as sex-specific, while other reports described selective effects of breathing through a specific nostril on the two divisions of the autonomic nervous system, irrespective of sex. There are also yoga breathing techniques which involve voluntary uninostril breathing. These techniques also influenced the autonomic activity based on the patent nostril rather than sex. These descriptions were in line with experiential observations of the ancient sages described in classical yoga texts. This paper summarizes these perspectives on uninostril breathing.

Yoga breathing through a particular nostril increases spatial memory scores without lateralized effects.

Uninostril breathing facilitates the performance on spatial and verbal cognitive tasks, said to be right and left brain functions, respectively. Since hemispheric memory functions are also known to be lateralized, the present study assessed the effects of uninostril breathing on the performance in verbal and spatial memory tests. School children (N = 108 whose ages ranged from 10 to 17 years) were randomly assigned to four groups. Each group practiced a specific yoga breathing technique: (i) right nostril breathing, (ii) left nostril breathing, (iii) alternate nostril breathing, or (iv) breath awareness without manipulation of nostrils. These techniques were practiced for 10 days. Verbal and spatial memory was assessed initially and after 10 days. An age-matched control group of 27 were similarly assessed. All 4 trained groups showed a significant increase in spatial test scores at retest, but the control group showed no change. Average increase in spatial memory scores for the trained groups was 84%. It appears yoga breathing increases spatial rather than verbal scores, without a lateralized effect.

Yoga-based guided relaxation reduces sympathetic activity judged from baseline levels.

35 male volunteers whose ages ranged from 20 to 46 years were studied in two sessions of yoga-based guided relaxation and supine rest. Assessments of autonomic variables were made for 15 subjects, before, during, and after the practices, whereas oxygen consumption and breath volume were recorded for 25 subjects before and after both types of relaxation. A significant decrease in oxygen consumption and increase in breath volume were recorded after guided relaxation (paired t test). There were comparable reductions in heart rate and skin conductance during both types of relaxation. During guided relaxation the power of the low frequency component of the heart-rate variability spectrum reduced, whereas the power of the high frequency component increased, suggesting reduced sympathetic activity. Also, subjects with a baseline ratio of LF/HF > 0.5 showed a significant decrease in the ratio after guided relaxation, while subjects with a ratio < or = 0.5 at baseline showed no such change. The results suggest that sympathetic activity decreased after guided relaxation based on yoga, depending on the baseline levels.

Asthma: The yoga perspective. Part I. The somatopsychic imbalance in asthma: towards a holistic therapy.

While the standard physiological and even certain psychological characteristics of asthmatic patients are well known, the current diagnostic and therapeutic approach to asthma remains inadequate, as it neglects certain interrelated somatopsychic factors vital to an optimal diagnostic-therapeutic programme. These include the role of skeletal muscle tension and posture, the role of the 'voluntary' respiratory musculature, especially the diaphragm, as well as anxiety, emotional suppression and excessive self-consciousness, all of which may be precipitants rather than the outcome of the onset of asthma. On the basis of these neglected factors and others, implications for an optimally effective therapy are discussed. The physical medicine or physiotherapeutic, as well as other recent therapeutic approaches, are reviewed and evaluated. It is concluded that all of these therapies are too "specific," and that a more holistic approach is necessary (which is provided in 'Asthma: The Yoga Perspective,' Part II-"Yoga Therapy in the Treatment of Asthma").

Muscle power, dexterity skill and visual perception in community home girls trained in yoga or sports and in regular school girls.

The present study was conducted to compare critical flicker fusion frequency (CFF), degree of optical illusion ("di"), dexterity scores, and grip strength in three groups of subjects, viz community home girls who had learned yoga for 6 months (CHY), age-matched community home girls who had physical activity training for 6 months (CHP), and girls who were attending a regular school (SCH). There were equal numbers in each group for each of the 4 assessment (range 11 to 30 subjects) and age range was 12 to 16 years of age. The CHP group had significantly lower CFF and "di" was significantly higher (one factor ANOVA, t test for unpaired data) in the CHP group, both compared to CHY and SCH groups. Right hand grip strength was also significantly less in the CHP group compared to SCH. The results were explained by previous reports of high levels of anxiety and aggression in community-home groups, which is known to influence the four parameters described here. The better performance of the CHY group compared to CHP, suggested that yoga practice has a beneficial effect in these subjects.

Health status of nurses and yoga. I. Baseline data.

In this ongoing ICMR project on "Effect of Yoga on the Health of Nurses", some baseline data on the health of nurses of Nehru Hospital, P.G.I., Chandigarh are reported. This was obtained before the start of yoga therapy in selected cases and collected with the help of six psychological tools. Out of a total of 501 nurses, 452 (90.2%) could be contacted and studied. Mean age was 30.43 years and mean years of service 9.93 years. Mean scores on the psychological tests indicated poor health status of nurses, average neuroticism, depressive tendencies and role stress. Sense of Well-Being was high in them. The data is discussed in the light of researches in this area. This is the first of a series of three articles to be published in the Journal.

Treatment of essential hypertension with yoga relaxation therapy in a USAF aviator: a case report.

A 46-year-old Caucasian male USAF aviator with a 6-year history of mild essential hypertension (medical waiver for flight duty) under unsuccessful treatment with hydrochlorothiazide, dietary modification, and exercise, was subsequently trained in yoga relaxation. After 6 weeks, medication had been discontinued, and his diastolic blood pressure remained within normal levels. The patient was subsequently returned to full flight status without recurrence of diastolic hypertension at followup 6 months later. Relaxation training, of which yoga is one type, has been reported in the medical literature to have wide clinical application. It should be considered as a nonpharmacological therapy adjunct or alternative for medical disorders among personnel in occupations (e.g., aviation) where the side effects from medications are of great concern and could be disqualifying from those duties.

Effect of short term yoga practice on ventilatory function tests.

Twentyfive normal male volunteers undergoing a ten weeks course in the practice of yoga have been studied by some parameters of ventilatory functions tests. The observations recorded at the end of ten weeks of the course have shown improved ventilatory functions in the form of lowered respiratory rate, increased forced vital capacity, FEV1, maximum breathing capacity and breath holding time, while tidal volume and %FEV1, did not reveal any significant change. Thus, a combined practice of yoga seems to be beneficial on respiratory efficiency.

Role of yoga in management of essential hypertension.

Twenty five patients of essential hypertension were studied. Of these, 20 patients were not given any antihypertensive drug treatment (Group A); other 5 had to be put on antihypertensive drugs before including them in the study (Group B). These patients were demonstrated "Shavasana" and trained to perform it correctly. Shavasana therapy was continued for six months. There was a statistically significant fall in both mean systolic and diastolic pressure of both groups. Further, there was a significant reduction in doses of antihypertensive drugs, being given to patients of group B. In 65% patients of group A, blood pressure could be controlled with Shavasana only and no drug was needed in them at all. Blood pressure rose significantly to pre-Shavasana levels in patients who left practising yoga. Thus, with use of yoga (Shavasana) in therapy of hypertension, requirement of antihypertensive drugs may be significantly decreased and in some cases may be totally dispensed with and it may be an useful adjunct in treatment of hypertension.

Plasticity of motor control systems demonstrated by yoga training.

The static motor performance was tested in two groups with 20 subjects in each (age range 17 to 22 years, and 5 females in each group). Tests were carried out at the beginning and end of a 10 day period. The test required being able to insert and hold a metal stylus within holes of varying sizes for 15 sec. Accidental contacts between the stylus and the sides of the holes, were registered on a counter as errors. During the 10 days one group (the yoga group) practised asanas (physical postures), pranayama (voluntary regulation of breathing), meditation, devotional sessions, and tratakas (visual focussing exercises). The control group followed their usual routine. At the end of 10 days the yoga group showed a significant reduction in number of errors (Wilcoxon paired signed ranks test), while the control group did not change. Our earlier study showed a similar improvement in children (9-13 years). It was interesting to note the same degree of plasticity in motor control systems in young adults. The implications for rehabilitation programmes have been discussed.

Postnatal development and reproductive performance of F1 progeny exposed in utero to an ayurvedic contraceptive: Pippaliyadi yoga.

Pippaliyadi yoga or pippaliyadi vati is an ayurvedic contraceptive used in India since ancient times. It is a combination of powdered fruit berries of Embelia ribes Burm.f. (Myrsinaceae), Piper longum L. (Piperaceae) and borax in equal proportion. Though the contraceptive potential is known since ancient times, no systematic developmental toxicity studies have been carried out. The present study was carried out to evaluate the postnatal developmental toxicity and the reproductive performance of the progeny exposed in utero to pippaliyadi. Pippaliyadi yoga was obtained from National Institute for Pharmaceutical Education and Research (NIPER), India and the developmental toxicity was studied by administering three doses, viz. 140, 300 and 700 mg/(kg day) to gravid females from day 6 to day 16 of gestation. Pippaliyadi did not have any adverse developmental effects with low doses, however, with the five times higher dose, a decrease in body weight of the pups was observed. The reproductive performance of the progeny born to mothers treated with pippaliyadi was not significantly affected. The present study suggests that in utero exposure to pippaliyadi does not have any adverse effect on the postnatal development and reproductive performance of the F(1) progeny.

Psychophysiological correlates of the practice of Tantric Yoga meditation.

Autonomic and electroencephalographic (EEG) correlates of Tantric Yoga meditation were studied in three groups of subjects as they progressed from normal consciousness into meditation. Groups differed in their level of meditation proficiency. Measures of skin resistance, heart rate, respiration, autonomic orienting responses, resting EEG, EEG alpha and theta frequencies, sleep-scored EEG, averaged evoked responses, and subjective experience were employed. Unlike most previously reported meditation studies, proficient meditators demonstrated increased autonomic activation during meditation while unexperienced meditators demonstrated autonomic relaxation. During meditation, proficient meditators demonstrated increased alpha and theta power, minimal evidence of EEG-defined sleep, and decreased autonomic orienting to external stimulation. An episode of sudden autonomic activation was observed that was characterized by the meditator as an approach to the Yogic ecstatic state of intense concentration. These findings challenge the current "relaxation" model of meditative states.
