A recent study shows that auditory stimuli and narratives have a clear and reproducible effect on our heart rate — No one will be too surprised to hear that certain aspects of stories — say a surprise scare in a horror movie — can influence our physiology, specifically our heart rate. What is however more interesting is the result of a recent study published in Cell Reports which showed that…

Yudemon’s first soundscape is now available — Last week I published the results of a self-study using different soundscapes during HRV training. The full soundscape I developed for this purpose, and specifically designed for my resonance frequency, showed an HRV increase of over 20% compared to silence. You can find the full details of this study —…

A self-study, and initial considerations on sound design for resonance breathing — [TLDR: I designed soundscapes specifically for resonance breathing, and tested them on myself, showing on average a 25% increase in HRV compared to silence. I have also released the soundscapes for a range of different breathing frequencies on all major music platforms.] Sounds and music can have a profound impact…

Introducing the Idea of a “Resonance Ratio.” — It is well established that breathing at a certain frequency, known as the resonance frequency, triggers a strong cardiovascular response that maximizes heart rate variability (HRV). Determining this frequency, which varies from person to person, usually forms the starting point for HRV biofeedback training. What is however less often considered…

A detailed study to determine the optimal breathing frequency that maximizes HRV response for biofeedback training — Heart rate variability (HRV) biofeedback training promises to strengthen the response of the autonomic nervous system (ANS) and increase adaptability and resilience, physiologically as well as mentally. It relies on the strong coupling between breath and heart, and more specifically the fact that slow breathing at a certain frequency —…
