Wim Hof Breathing Timer

A visual breathing timer for the Wim Hof Method. Follow the breath count, hold through retention, then the recovery breath. Works entirely in your browser.

How the Wim Hof Method Works

The Wim Hof Method uses three phases: deep controlled breaths (30–40), breath retention on empty lungs, then a recovery breath held on full lungs. The rapid breathing lowers blood CO₂, which is what lets you hold the retention longer — but it also means this is a stressor, not a relaxation exercise. For the full step-by-step protocol and safety limits, read our Wim Hof breathing guide.

⚠️ Safety

• Never practice this in or near water — shallow water blackout can drown you.
• Always do it seated or lying down on dry land.
• Stop if you feel faint, confused, or experience chest pain.
• Not for people with heart disease, high blood pressure, epilepsy, or who are pregnant.
