Thoughts on improving productivity and creativity.

“Why the f*ck do I feel so unproductive and uncreative?”

It was August 2017 as I wrote these words in my notebook. I was sitting in my quiet room in an old guesthouse in the small town of Zao Onsen, overlooking the mountains of Yamagata Prefecture.

I was on holiday, a slow trip on local trains through rural Japan. I…


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…

We crave connection.

Whether physical or digital, through active interaction with others or by passively observing their lives through news and social media feeds, we want to be connected.

Connection makes us feel like we are part of a community — even more so in times where being part of…


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 —…

On embracing your inner introvert and finding restorative niches in your daily life.

It used to be that character was the highest ideal a person could aspire to.

Actions spoke louder than words.

Being quiet, disciplined, and honorable was seen as good and strong.

But as the late historian Warren Susman remarked, this all changed at the beginning of the 20th century, as…


The Biomechanics of HRV Biofeedback Training and Resonance Breathing

Heart rate variability (HRV) biofeedback training and resonance breathing are based on the fact that our breathing has a direct impact on the rest of our physiology, specifically our heart. In this short article I will outline the mechanisms behind this.

The process begins with the diaphragm.

On the inhale…


Why absolute and hourly income miss the main point

Compensation is one of the main criteria for evaluating a job.

A six-figure income has for a long time been a benchmark of success, and what many people — especially millennials — aspire to.

But while absolute salary is a very alluring metric, it only paints a very limited picture…


Elevating Human Happiness, Performance, and Wellbeing through Creative Technology

Our body and mind are not separate entities.

Many would even argue that there is no strong reason to believe that the mind is anything but a manifestation of the body.

Whether you fall into this group or believe that your mind is more than just an emergent phenomenon of…
