The effect of right, left, and alternate nostril yoga breathing (i.e., RNYB, LNYB, and ANYB, respectively) were compared with breath awareness (BAW) and normal breathing (CTL). Autonomic and respiratory variables were studied in 21 male volunteers with ages between 18 and 45 years and experience in the yoga breathing practices between 3 and 48 months. Subjects were assessed in five experimental sessions on five separate days. The sessions were in fixed possible sequences and subjects were assigned to a sequence randomly. Each session was for 40 min; 30 min for the breathing practice, preceded and followed by 5 min of quiet sitting. Assessments included heart rate variability, skin conductance, finger plethysmogram amplitude, breath rate, and blood pressure. Following RNYB there was a significant increase in systolic, diastolic and mean pressure. In contrast, the systolic and diastolic pressure decreased after ANYB and the systolic and mean pressure were lower after LNYB. Hence, unilateral nostril yoga breathing practices appear to influence the blood pressure in different ways. These effects suggest possible therapeutic applications.
比较了右鼻孔、左鼻孔和交替鼻孔瑜伽呼吸（即分别为右鼻孔瑜伽呼吸、左鼻孔瑜伽呼吸和交替鼻孔瑜伽呼吸）与呼吸觉知（BAW）和正常呼吸（CTL）的效果。对21名年龄在18至45岁之间、有3至48个月瑜伽呼吸练习经验的男性志愿者的自主神经和呼吸变量进行了研究。在五个不同的日子里对受试者进行了五次实验。实验按照固定的可能顺序进行，受试者被随机分配到一个顺序。每个实验持续40分钟；30分钟用于呼吸练习，前后各有5分钟的安静坐姿。评估包括心率变异性、皮肤电导、手指容积描记图幅度、呼吸频率和血压。右鼻孔瑜伽呼吸后，收缩压、舒张压和平均压显著升高。相比之下，交替鼻孔瑜伽呼吸后收缩压和舒张压下降，左鼻孔瑜伽呼吸后收缩压和平均压较低。因此，单侧鼻孔瑜伽呼吸练习似乎以不同方式影响血压。这些影响提示了可能的治疗应用。
