2.4. Neurofeedback and Heart Rhythm (Biofeedback) Regulation

The following studies further support the integration of heart rate variability (HRV) alongside EEG signals as a strong approach in neurofeedback and biofeedback applications, from enhancing sleep and reducing stress to improving mental health and boosting performance across various domains. Enhanced Neurofeedback and heart rhythm is an approach that combines brainwave training (neurofeedback) with heart rate variability (HRV) biofeedback to help individuals improve their mental and physical well-being. Neurofeedback trains the brain to achieve healthier patterns, while HRV biofeedback helps regulate the autonomic nervous system by promoting calm, balanced heart rhythms.
