스와라 호흡(svara prāṇāyāma)과 스트레스의 상관성에 대한 연구

Abstract

Stress is often called the source of all kind of diseases. Yoga has many therapeutic techniques. Today, first of all, āsanas are most popular yogic therapeutic skills and, secondly, meditations are second popular ones. With meditations, attention of yogic breathing techniques have been also increased gradually. In this study, through svara prāṇāyāma(one nostril breathing), we make effort to be in search of possibilities of improving stages of stress. In the post-classical yoga traditions, theory of subtle body has been exquisitely developed. The same are Haṭha yoga and Svara yoga. In this paper, we focus on the theory which was appeared in the the Śiva-Svarodaya and Svara Chintamani. Iḍā nāḍī and piṅgalā nāḍī, one of the core idea of this theory, are connected to the streams of left nostril breathing and right nostril breathing. And both nāḍīs are frequently considered as corresponding to sympathetic and parasympathetic nerves of the autonomic nervous system in modern medical theory of body. Stress has a direct and great influence on the autonomous nervous system which does detailed inner control function necessary for maintaining proper inner circumstance of body. It is known to researchers that measuring the effects of stress by HRV is very efficient and objective. First of all, in this research, autonomous nervous system is effected by svara prāṇāyāma based on correlations of nāḍīs and symathetic･parasympathetic nerves. And then changes of stress stages are measured. 48 Pharmaceutical salesmen as subjects of the experiment are practiced svara prāṇāyāma. HRV measurement results of before and after the breathing show us conclusions which the breathing technique has clearly influence on autonomous nervous system and decreasing stress stages partly.
