Follow the four phases
- Inhale gently as the circle expands.
- Pause only if it feels comfortable.
- Exhale gently as the circle shrinks.
- Pause again only if it feels comfortable, then repeat.
The on-screen guide shows each phase. You can stop it at any point. If holding your breath feels uncomfortable, breathe normally instead. Never hold your breath underwater.
Breathing exercises cannot remove the risks of cold water exposure. Read the safety guide and leave the water if you feel unwell.
