Although there are many quantitative studies in the international literature on yoga, the number of qualitative studies showing the experience of yoga practice is insufficient. An accurate demonstration of yoga participents experiences, opinions, and judgments on this subject requires a qualitative, rather than a quantitative approach.</p><p><strong>Purpose: </strong>This study was to explore the benefit perceived by adults who have practiced yoga for a long time.</p><p><strong>Design and method: </strong>This qualitative study is based on a hermeneutic-phenomenological approach. The research sample consisted of 18 adults who volunteered to participate in the research and regularly joined yoga practice. The study data were collected through individual and focus group interviews with the participants who practise yoga and analyzed by content analysis method.</p><p><strong>Results: </strong>We created five themes. Themes coded by researchers: meaning of the concept of yoga (theme 1), physical, mental, and social state before starting yoga (theme 2), reasons for practising yoga (theme 3), the participants' experiences related to their physical and mental health and social relationships (theme 4), and difficulties of doing yoga (theme 5).

The positive experiences of the participants in the study included decrease in pain and flexibility, increase in sleep quality, development of positive personality traits, increase in self-esteem, and coping with anxiety and stress more effectively.

The two types of SFA, the observer perspective and self-focus on body sensation, increase anxiety in individuals with high levels of social anxiety. However, the triggers of each SFA remain unclear. This study used ecological momentary assessment to identify the factors that elicit SFA in real-life social scenarios.</p><p><strong>Methods: </strong>The study obtained 316 samples from 22 Japanese university students (4 male:18 female) with high social anxiety who completed momentary measures of stimulus perception and two types of SFA for 10 days. Links to online questionnaires were sent to the participants via e-mails 3 times a day. First, multilevel single regression analyses were used to identify the stimuli that induced the two types of SFA.

Next, for the variables that were significantly predictive in these analyses, multilevel multiple regression analyses were conducted with fear of each stimulus as a control variable.</p><p><strong>Results: </strong>Perception of gaze, evaluation, and authority predicted SFA from the observer perspective. Perception of gaze also predicted self-focus on body sensation. In addition, the perception of positive response and that of stranger predicted self-focus on body sensation depended on gender, implying that the positive response perception of female participants predicted self-focus on body sensation.
