Breathing Frequency is a free resonance frequency breathing test and a paced breathing timer. It exists because the test in Leah Lagos's Heart Breath Mind and in the Lehrer and Vaschillo research needs a pacer that steps through the rates and asks the right question after each one, and the pacers online either do not do that or hide it behind an app subscription. Here the protocol is on the page, the sources are listed, and the tool runs in your browser.
Who runs it
Breathing Frequency is written and published by Adrian Hall, through Galena Hall, a small independent publisher of reference and tool websites. Adrian built the site after running Leah Lagos's ten-week programme from Heart Breath Mind and finding that the pacers online either skip the test that the programme starts with, or put it behind an app subscription. He writes every page here and answers the contact address himself.
He is not a doctor, a physiotherapist or a breathing coach, and the site does not pretend otherwise. What that means in practice: nothing here is medical advice, every factual claim names the study it comes from so you can read the source rather than trust us, and the people who should speak to a clinician before slow-breathing practice are listed on every tool page. Corrections go to the contact page and are made in public.
How it is funded
The tools are free and carry no advertising while you are breathing. The rest screens between test rates and the article pages may carry advertising in future. The books page uses Amazon affiliate links, marked as such. We have no relationship with any app, device or course, and take no payment for placement.
Accuracy
Every factual statement on the site names its source, and the timing code is public with automated tests. If a source is misread, a number is wrong, or a claim goes beyond what its study supports, tell us and we will fix it.
