Wim Hof-style breathing commonly involves: 1. 30-40 deep breaths 2. Breath hold on empty lungs (1-3 minutes) 3. Recovery breath (15 seconds) 4. Repeat 3-4 rounds People use this style of guided breathwork for meditation, focus, and structured breathing practice. Individual experiences vary, and the app does not make medical outcome guarantees. ## Safety and scope Deep Breathe is a guidance and timing tool, not a medical device or healthcare service. Breath-hold exercises should be practised seated or lying down in a safe place, never in water or while driving. People who are pregnant or have a medical condition should ask a qualified clinician whether this type of breathwork is appropriate for them.
