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.
