DEEP BREATHING EXERCISES
About
Deep Breathing Exercises is a free breathing visualizer and a set of evidence-informed guides for calm, focus, and sleep.
What this is
This site provides simple, guided breathing sessions (box breathing, 4-7-8, coherent breathing for HRV, and the physiological sigh) plus short guides explaining when to use each technique.
What this is not
This is not medical treatment. If you have a cardiopulmonary condition, are pregnant, or have a history of fainting, keep breathing gentle, avoid long breath holds, and consult a clinician for personalized advice.
Who built this
Deep Breathing Exercises is built by Abi Abiassi, founder, photographer, and breathwork practitioner. He built it as a free visualizer for the techniques he uses daily.
Editorial approach
Each technique page names the practitioner or tradition it comes from, links out to the peer-reviewed research that informs the claims, and shows when it was last updated. Where evidence is weak, we say so.
