That breathing you do before paddling out — the big rapid inhales to feel “ready” — it’s actually cutting off oxygen to your brain.
Jason Rice has trained WSL pros and big‑wave surfers for decades. He knows exactly what happens when breath work goes wrong in the ocean. And what he explained here stopped me cold.
It’s called the Bohr Effect.
When you hyperventilate, CO2 drops so low that oxygen can’t release from your haemoglobin into your cells.
You feel alert.
You might even feel calm.
But your brain is being starved.
That’s not preparation — that’s impairment.
And there’s a reason has spent years teaching surfers how to avoid this. One of the biggest breathwork brands in the world is facing class‑action lawsuits over ocean‑related deaths. This isn’t fringe. It’s physiology.
If you’re paddling out at the Pass or sitting in the lineup at Brunswick waiting for a set — how you breathe in those minutes matters more than most people realise. Jason breaks down exactly what to do instead.
Free 6‑week surf strength and conditioning program in the bio — because breath, movement and load capacity all talk to each other, and most programs only address one.
Thank you Gio.
