Free to use
The breathing tools on Breathing Frequency are free for personal use.
No guarantee
We work to keep the timing correct and the text tied to its sources, published at how it works, but the site is provided as is.
Not medical advice
Breathing Frequency is educational. It does not diagnose, treat or prevent any condition, and nothing on it is medical advice. Slow breathing is not suitable for everyone; the people who should ask a clinician first are listed on every tool page. You use the tools at your own risk, and you should stop if you feel unwell.
The site is not affiliated with any author, publisher, app or device maker named on it. Book links are affiliate links and are marked as such.
