 note = {application/pdf, Subjective psychological evaluation and objective measurement of autonomic nerve activity were used to evaluate whether mindfulness breathing meditation and yoga therapy are effective in improving stress and depression in college students. Nine students （3 females, 6 males, 21 years ± 1.2 years old） participated in this study as voluntary subjects. Subjects did mindfulness breathing meditation （approximately 2 minutes） or yoga therapy （approximately 10 minutes） watching assigned video once or twice daily for 8 weeks. Measurement of autonomic nerve function was performed by wearing a portable electrocardiogram, and from the obtained time-series data, the R wave interval and the power value of each frequency band from ECG, LF: 0.04－0.15 Hz and HF: 0.15－0.4 Hz was used as indexes of autonomic nerve activity. A random number generation task was presented while autonomic nerve activity was measured, and changes in autonomic nerve activity were tracked. Psychological test items are POMS （mood scale）, STAI （anxiety scale）, Japanese Mindful Attention Awareness Scale （MAAS, mindfulness scale）, Rosenberg self-esteem scale, and GHQ28. As a result, 8 weeks of practice significantly increased POMS ‘vitality’ （p＝0.03） and significantly decreased ‘fatigue’ （t＝0.02）. There was also a significant increase in Rosenberg’s self-esteem （p＝0.049）. There were no significant changes in other rating scales. For MAAS, we also examined the rate of change before and after practice. The ratio of score after practice/score before practice decreased after treatment （p＝0.039, r＝－0.77）. The average values   of HR, LF, and HF did not change before and after practice. However, focusing on the change at the time of event switching, we calculated the rate of change of HR and HRV for 20 seconds before and after the start of the random number generation task and the end of the task. As a result, in HF fluctuations （parasympathetic index） the rate of change in the 20 seconds before and after the start of the random number generation task decreased significantly after the practice compared to that of before （p＝0.038）. A reduction in HF fluctuations, which is also the stress response of HRV, may indicate a reduction in psychological tension in the face of stress. In addition, in this study, an interesting change was observed in that people were normalized to an appropriate state of mindfulness, suggesting that a high score on the mindfulness scale does not necessarily indicate psychological adaptation.},
