The growing popularity of application-based meditation has driven the development of new technological features in this field such as the use of cardiac biofeedback, aimed at helping users train their attention to interoceptive stimuli while meditating. However, despite the innovativeness of this approach, the effectiveness of cardiac biofeedback-assisted meditation in enhancing interoception...
Recent advancements in virtual reality (VR)-enhanced mindfulness training have demonstrated efficacy in reducing anxiety, particularly among novice practitioners and university students. However, existing VR mindfulness interventions predominantly rely on static natural environments without incorporating interactive elements, limiting their capacity to engage users dynamically. To address this...
Many studies have examined the effects of meditation practice focused on the normal breath on vagal tone with mixed results. Heart Rhythm Meditation (HRM) is a unique meditation form that engages in the deep slow full breath, and puts the focus of attention on the heart. This form of breathing likely stimulates the vagus nerve with greater intensity. The purpose of this study was (a) to examine...
Slow paced breathing has been demonstrated to provide significant health benefits for a person’s health, and, during breathing sessions, it is desirable to monitor that a person is actually compliant with the breath pacer. We explore the potential use of pulse rate variability to monitor compliance with a breath pacer during meditation sessions. The study involved 6 human subjects each...
