Abstract

Pranayama (breathing exercise), one of the yogic techniques can produce different physiological responses in healthy individuals. The responses of Alternate Nostril Breathing (ANB) the Nadisudhi Pranayama on some cardio-respiratory functions were investigated in healthy young adults. The subjects performed ANB exercise (15 minutes everyday in the morning) for four weeks. Cardio-respiratory parameters were recorded before and after 4-weeks training period. A significant increment in Peak expiratory flow rate (PEFR L/min) and Pulse pressure (PP) was noted. Although Systolic blood pressure (SBP) was decreased insignificantly, the decrease in pulse rate (PR), respiratory rate (RR), diastolic blood pressure (DBP) were significant. Results indicate that regular practice of ANB (Nadisudhi) increases parasympathetic activity.

Objective This interventional randomized controlled study aimed to evaluate the immediate hemodynamic effects of slow uninostril and alternate nostril breathing (ANB) patterns in normotensive adults. Methods A total of 132 normotensive adults aged 25–50 years were randomly allocated into one of four groups: Chandra anulom vilom (CAV), Surya anulom vilom (SAV), Anuloma viloma /ANB, or control. Hemodynamic parameters including systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and pulse rate were measured at baseline, once in between two prāṇāyāma rounds, postintervention, and 5 min after intervention completed. Results The study showed a significant decrease in SBP and DBP postintervention in the CAV and ANB groups compared to the SAV group. Furthermore, MAP was significantly lower in the ANB group relative to the control group. These results suggest that different types of prāṇāyāma can induce immediate changes in hemodynamic parameters even in nonpractitioners of yoga . Conclusion The study provides insights into the potential benefits of specific prāṇāyāma techniques on hemodynamic changes in normotensive individuals, indicating that such techniques could be beneficial in managing BP and overall hemodynamic status.

Background: Chandra Nadi Shuddhi Pranayama is a type of alternate nostril breathing which is the control-positive inhalation and exhalation process. Alternate nostril breathing technique shows the best result in health improvement especially in controlling the blood pressure. It activates the parasympathetic nervous system which dilates blood vessels, decreases the heart rate which leads to reduce blood pressure. Many studies have been done to see effects of breathing exercises on cardiovascular system however, no such studies were done to see specific and immediate effect of Chandra Nadi Shuddhi on cardiovascular system. In this article, we will look how Chandra Nadi Shuddhi improves blood pressure, heart rate, and rate pressure product. Methods: Ethical clearance and participant consent was taken. Study design was experimental study. The 80 subjects were taken by convenient sampling. Participants were asked to perform 27 rounds of the Chandra Nadi Shuddhi Pranayama and outcome measures were assessed before and immediately after performing Chandra Nadi Shuddhi. The normality of the data was assessed using parametric paired t test. Results: Immediate effect of Chandra Nadi Shuddhi Pranayama showed that there was statistically significant decrease in blood pressure, heart rate and rate pressure product (p=0.0001, 0.0045, 0.0001 respectively) Conclusions: There is immediate effects of Chandra Nadi Shuddhi Pranayama on individuals with normal blood pressure.These results suggest a possible role for this technique in helping to control hypertension, lower anxiety and depression, improve breathing and immunity.
... the affect-adaptive system can also reduce elevated arousal. in this case, it is crucial to distinguish whether the heightened arousal is caused by high task demand or other factors, so the system can either adjust the task demand or address other sources of concern, such as by playing soothing noises like ocean sounds (cheng and tsai 2016) tranquil music (Nilsson et al. 2005), or guided breathing exercises (Dhungel et al. 2008). additional methods to decrease arousal include providing an anti-stress ball for kneading (srivarsan et al. 2021), if the task can be performed with one hand, or equipping the operator's seat with technologies that promote relaxation and mitigate discomfort, such as massage programs or a heating or cooling function. ...

Extensive evaluations exist concerning the linkage between objective task demands and subsequent effects on user performance. However, the human user also experiences a range of emotions related to external task demands. Problematically, little is known about the associations between emotional valence, and arousal associated with the task demand-performance axis. In this paper, we advance a theoretical model concerning such interactive influences using three dimensions: (1) emotional valence, (2) arousal, and (3) task demand. The model evaluates the impact of these dimensions on user performance. It also identifies critical emotional user states, particularly those resulting in negative performance effects, as well as non-critical emotional states that can positively impact performance. Finally, we discuss the implications for affect-adaptive systems that can mitigate the impact of critical emotional states while leveraging the benefits of non-critical ones.
... [6] Four weeks of Nadishodhan pranayama showed significant decrease in heart rate, diastolic blood pressure, systolic blood pressure besides significant increase in pulse pressure. [7] During 'OM recitation' meditation, amongst the treatment group, there was a significant reduction in heart rate as compared to the control group in which non-targeted thinking (dhyana, as per Ashtang Yoga) was encouraged. [8,9].All these studies reported the effects of individual pranayama or meditation practice for minimum of 4 weeks to 6 months. ...

Relaxation Music (RM), Mindfulness Meditation (MM) and Relaxation Techniques (RTs) are widely used in healthcare contexts and these interventions have been investigated for integrated healthcare, psychotherapy treatment and collaborative and multidisciplinary approaches. However, the information exchange between healthcare practitioners in the UK and South Korea has so far been limited and cross-cultural comparisons of RM, MM and RTs within the healthcare context of the UK and Korea have previously been unexplored. The aim of this paper is to present a summary of the key aspects from an unpublished PhD study (Hwang, 2018). The focus of this paper is to explore the similarities and differences in understanding the use of RM, MM and RTs between practitioners in the UK and Korea. A qualitative case study methodology was used and data were collected through semi-structured interviews with six Korean and six UK healthcare practitioners in three professional areas: medical practice, meditation, and music therapy. Similarities (in outlooks and purposes, methods, interests and concerns, responses and approaches) and differences (in historical and traditional influences, behavioural patterns and particular emphases) were identified. The value of cross-cultural and multidisciplinary research is increasingly recognised and the use of RM, MM and RTs as mind-body-spirit interventions are considered to be useful integrated treatments. This paper contributes to cross-cultural qualitative research between South Korea and the UK and integrating theory and practice with respect to RM, MM and RTs.

Pranayama, an ancient Indian breathing exercise technique, regulates the length, frequency, and timing of breaths. Pranayama releases the breath and allows prana also facilitates the flow of life force throughout the body, helping it to heal, relax, and become more energized. Cardiovascular endurance, also known as aerobic fitness. Benefits of cardiovascular endurance include lowering blood pressure and cholesterol, reducing the risk of heart and blood vessel problems, strengthening the heart and lungs, enhancing mental performance and improving the overall quality of life. Nose is the primary system for inhalation and exhalation in many breathing exercises. This technique is based on the extraordinary sensitivity of our lungs, optimizing the air we breathe for entry into the respiratory system, where the air's temperature and humidity are adjusted. This chapter will explain how Pranayama enhances airflow into the body, generating both physical and subtle heat that ignites the internal fires of the body and mind and that improves cardio-pulmonary health by enhancing the circulation.

Objectives: Lung function and functional capacity gradually decline even in asymptomatic individual with age. Alternate nostril breathing (ANB) is a breathing exercise used to modulate the pace of breathing. The present study aimed to evaluate the efficacy of ANB on pulmonary function and physical functional capacity in normal adults across different age groups. Methods: 48 participants aged 20-50 years were stratified based on age and were assigned into young (experimental and control group) and old age strata (experimental and control group) for this randomized controlled trial. Pulmonary function (FEV₁, FVC, FEV₁/FVC, PIFR, and PEFR) and physical functional capacity (6MWD) were assessed before and after the test. Experimental groups practiced ANB for 15 minutes for 4 weeks (6 days/week) in front of primary researcher. No intervention was given to control groups. Between groups analysis was done by Mann Whitney U test whereas, Wilcoxon signed rank test was used for within group analysis. Results: Significant differences were found in median values of FEV₁ (2.21-2.47, p=.002), FVC (2.39-2.77, p=.003), PEFR (5.30-6.45, p=.002), and PIFR (3.85-4.22, p=.05) between total experimental and total control groups, but not in FEV₁/FVC ( p=.41 )and PIFR (p=20). Post treatment analysis of total experimental group showed significant improvement in FEV₁ (p= .0001), FVC (p=.0001), PEFR (p= .0001), PIFR (p= .002) and 6MWD (p= .0001), while total control group had no significant improvement in any component (p˃.05). Conclusion: Alternate nostril breathing can be used as a maneuver to improve age related lung function decrement.

The heart rate variability (HRV) is an indicator of the cardiac autonomic control. Two spectral components are usually recorded, viz. high frequency (0.15-0.50 Hz), which is due to vagal efferent activity and a low frequency component (0.05-0.15 Hz), due to sympathetic activity. The present study was conducted to study the HRV in two yoga practices which have been previously reported to have opposite effects, viz, sympathetic stimulation (kapalabhati, breathing at high frequency, i.e., 2.0 Hz) and reduced sympathetic activity (nadisuddhi, alternate nostril breathing). Twelve male volunteers (age range, 21 to 33 years) were assessed before and after each practice on separate days. The electrocardiogram (lead I) was digitized on-line and off-line analysis was done. The results showed a significant increase in low frequency (LF) power and LF/HF ratio while high frequency (HF) power was significantly lower following kapalabhati. There were no significant changes following nadisuddhi. The results suggest that kapalabhati modifies the autonomic status by increasing sympathetic activity with reduced vagal activity. The study also suggests that HRV is a more useful psychophysiological measure than heart rate alone.

We planned to undertake a comparative study of the effect of short term (three weeks) training in savitri (slow breathing) and bhastrika (fast breathing) pranayams on respiratory pressures and endurance, reaction time, blood pressure, heart rate, rate-pressure product and double product. Thirty student volunteers were divided into two groups of fifteen each. Group I was given training in savitri pranayam that involves slow, rhythmic, and deep breathing. Group II was given training in bhastrika pranayam, which is bellows-type rapid and deep breathing. Parameters were measured before and after three week training period. Savitri pranayam produced a significant increase in respiratory pressures and respiratory endurance. In both the groups, there was an appreciable but statistically insignificant shortening of reaction time. Heart rate, rate-pressure product and double product decreased in savitri pranayam group but increased significantly in bhastrika group. It is concluded that different types of pranayams produce different physiological responses in normal young volunteers.

Responses from inflation of 1 lung with different pressures were studied using relatively intact dogs, dogs with denervated aortic baroreceptors and a controlled pressure to the carotid baroreceptors, and dogs with open chests and the inflated lung artificially perfused. Reflex tachycardia usually resulted from inflation of normally perfused lungs with 10 to 20 cm H2O pressure. Reflex bradycardia usually occurred during inflation of normally perfused lungs with pressure of 30 to 40 cm H2O provided arterial baroreceptor input was controlled, inflation with 20 cm H2O immediately following hyperinflation, and inflation with 10 to 40 cm H2O of an artificially perfused lung. Hindlimb vascular resistance usually showed a small increase during inflation at the lower pressures. At the higher inflation pressures vasomotor responses were variable and vasodilatation sometimes occurred. Although the mechanisms responsible are not known, these experiments define the conditions favoring different responses and help to explain the differing reports of previous investigators.

1. A maintained inflation of the lungs caused a reflex reduction in total systemic vascular resistance in anaesthetized dogs under conditions in which the systemic circulation was perfused at constant blood flow and the arterial blood P O 2 and P CO 2 were maintained constant. 2. The fall in systemic arterial perfusion pressure evoked by inflation of the lungs was accompanied by an increase in blood flow to the lower limbs and a reduction in their calculated vascular resistance. Since the fall in resistance occurred when the limb was perfused either at constant pressure or at constant blood flow, it must be due to vasodilatation. 3. Lung inflation caused vasodilatation in skin, muscle, and in the splanchnic vascular bed. The responses in vertebral circulation were, however, small and variable. 4. The vasodilator responses in the vascular territories studied were reflex in nature, being abolished by cutting the cervical vagosympathetic nerves, in which run the afferent fibres, or by interrupting the sympathetic pathways to the blood vessels. 5. In the intact limb, muscle, skin and splanchnic vascular bed, the vasodilator responses to lung inflation were unaffected by atropine or propranolol, but were abolished by hexamethonium, dibenyline and bretylium tosylate, indicating that they were due predominantly to a reduction in the activity in sympathetic adrenergic vasoconstrictor fibres.

Practice of breathing exercises like pranayama is known to improve autonomic function by changing sympathetic or parasympathetic activity. Therefore, in the present study the effect of breathing exercises on autonomic functions was performed in young volunteers in the age group of 17-19 yr. A total of 60 male undergraduate medical students were randomly divided into two groups: slow breathing group (that practiced slow breathing exercise) and the fast breathing group (that practiced fast breathing exercise). The breathing exercises were practiced for a period of three months. Autonomic function tests were performed before and after the practice of breathing exercises. The increased parasympathetic activity and decreased sympathetic activity were observed in slow breathing group, whereas no significant change in autonomic functions was observed in the fast breathing group. The findings of the present study show that regular practice of slow breathing exercise for three months improves autonomic functions, while practice of fast breathing exercise for the same duration does not affect the autonomic functions.

The modern living lifestyle is known to produce various physical and psychological stresses and subject the individual to produce oxidative stresses as well. The aim of this study has been to assess the effect of yogic breathing exercises (pranayama) on the oxidatives stress. The study group consisted of 30 young male volunteers, trained for the purpose of this study and an equal number of controls were used. The free radicals and Super oxide dismutase levels were measured before the study and at the end of the study. The free radicals were decreased significantly in the study group but the SOD was increased insignificantly as compared to the control group. Yogic breathing exercises not only help in relieving the stresses of life but also improve the antioxidant status of the individual. An improvement in the antioxidant status is helpful in preventing many pathological processes that are known with impaired antioxidant system of body.

Alternate nostril breathing (ANB) may modulate cardio-respiratory and autonomic functions. However, the studies are scarce and results highly conflicting. The present study was conducted in healthy young volunteers comprising of males (n=20) and females (n=20) in range of 17-22 years. In both groups respiratory rate (RR/min), heart rate (HR/ min), systolic blood pressure (SBP; mm Hg), diastolic blood pressure (DBP; mm Hg), peak expiratory flow rate (PEFR; L/min) and galvanic skin resistance (GSR; microV) were recorded thrice; once as control and then after 15 min (acute exposure) and following 8 wks of training in ANB (15 min daily). In males the control RR was 16.60 +/- 2.01, HR 75.75 +/- 11.07, SBP-115.9 +/- 7.33, DBP 70.4 +/- 6.28 and PEFR 550.00 +/- 51.50. After 15 min of ANB-RR (14.75 +/- 1.41, P<0.001), HR (68.45 +/- 12.41, P<0.01) and SBP (113.6 +/- 6.04, P<0.05) fell significantly. After 8 wks of ANB training RR (12.35 +/- 1.35, P<0.0001), HR (63.20 +/- 11.11, P<0.001), SBP (109.5 +/- 5.61, P<0.001), declined to much greater extent and PEFR (571.50 +/- 46.26, P<0.01) rose significantly. In females the control RR was 17.25 +/- 1.89, HR-74.90 +/- 12.85, SBP-106.70 +/- 6.91, DBP-68.70 +/- 5.52 and PEFR-394.50 +/- 44.89. After 15 min of ANB RR (15.05 +/- 1.54, P<0.001) and HR (64.75 +/- 9.80, P<0.001) showed significant decline with concomitant rise in PEFR (407.00 +/- 2.31, P<0.05). Following 8 wks training the decrement in RR (12.60 +/-1.50, P<0.0001) and HR (63.30 +/- 8.65, P<0.001) was maintained. SBP (103.10 +/- 4.92, P<0.001) and DBP (65.8 +/- 5.54, P<0.001) decreased further and PEFR (421.00 +/- 38.51 P<0.001) rose, GSR was unaffected by ANB in both males and females. These results suggest that in general there is a tilt towards parasympathetic dominance by alternate nostril breathing. This breathing may be a useful adjuvant to medical therapy of hypertension and COPD.
