Infographic illustrating the physiological process of humming and deep breathing activating the vagus nerve, leading to relaxation and stress reduction.

Create a clear, scientifically sound infographic in landscape format explaining the physiological connection between humming-assisted breathing and stress regulation. The graphic should illustrate step-by-step: conscious breathing with humming → activation of the vagus nerve as part of the parasympathetic nervous system → physiological calming responses such as slowed breathing and reduced heart rate → subjective experience of relaxation and improved self-regulation. Use a clear, minimalist style with neutral colors, simple symbols, and easily legible labels. The graphic should be scientifically understandable, factual, and suitable for adult education, without childish illustrations or decorative elements. No esoteric depictions, no excessive detail, focus on clarity and scientific rigor. In German and in color. See more
