As a result, they often have negative emotions, which in turn may cause the disease depression, manic depression, insomnia and other symptoms after a long time. In the previous studies, meditation and deep breathing exercises can have a significant effect on your physical and mental relaxations .
In this study, we have integrated electrocardiogram (ECG), electromyogram (EMG), and also use Poincare Plot to analyze the emotional responses. Poincare Plot has the advantages of having simplified calculation process and being very suitable for a short time data analysis. By using HRV based on ECG, we can understand the balance of autonomic nervous activity, and EMG can be used to measure the contraction and relaxation of participants’ specific facial muscles. By using the self-designed emotional respose analysis system and applying the Pittsburgh Sleep Quality Index (PSQI) with Life Health Questionnaire (SF-36), we can select the healthy subjects who meets the requirements of our experiments objectively. In our research, we measured the related physiological responses of the subjects by stimulating them with different pictures. We also observe the effects of meditation relaxation exercises and deep breathing on the emotional responses of the subjects.
Finally, we found that the SD2,and SD2/SD1of Poincare Plot show higher outcome when watching more provocative picture. It indicates the increase of sympathetic activity. And after the subjects completing meditation practice or deep breathing exercises, the SD2 is significantly higher than before, and it represents that the emotional responses are not vulnerable to the interference of environmental stimulation.
