Freediving Breathwork
Before you learn to dive, you learn to breathe. Proper breathwork is the foundation of every breath-hold — and the thing most beginners get wrong.
The Science
Why Breathing Technique Matters
Understanding what's actually happening in your body changes how you train.
The urge to breathe is CO₂, not O₂
Most people assume they need to breathe when oxygen runs out. In reality, the urge is triggered by rising CO₂ levels in the blood. You almost always have more oxygen left than you think — your body is reacting to CO₂ before O₂ becomes critical.
Relaxation extends your dive
Tension burns oxygen. Every unnecessary muscle contraction shortens your breath-hold. The goal of breathwork is to train your nervous system to stay calm — so your body consumes oxygen as slowly as possible.
Slow breathing activates the dive reflex
Long, slow exhalations activate the parasympathetic nervous system. This lowers heart rate and blood pressure before you enter the water — priming your body for the mammalian dive reflex that kicks in on descent.
Techniques
The Three Essentials
Every freediving session involves these three phases. Get them right and everything else becomes easier.
Diaphragmatic Breathing
Breathing from the belly rather than the chest. The diaphragm — the large muscle below your lungs — should do most of the work. Place a hand on your stomach: it should rise on the inhale, fall on the exhale. Chest movement should be minimal.
How to practice
- Sit or lie comfortably with one hand on your belly
- Inhale slowly through your nose — belly rises first, then chest
- Exhale slowly and completely — belly falls, chest follows
- Aim for a slow, unforced rhythm — no straining
The Breathe-Up
The breathe-up is the calm breathing you do before a breath-hold. The goal is to relax your body and mind — not to take in extra oxygen. It should feel easy and slow. Most beginners make it too intense.
How to practice
- Breathe diaphragmatically for 2–3 minutes before your dive
- Keep the rhythm slow: roughly 6–8 breaths per minute
- Extend the exhale slightly longer than the inhale
- Stop when you feel calm — not when you feel "ready"
Safety
Never hyperventilate before a breath-hold. Rapid deep breathing flushes CO₂ and delays the urge to breathe, which can cause loss of consciousness with no warning. It is prohibited in all freediving training.
Recovery Breaths
What you do in the first few seconds after surfacing is as important as the dive itself. A structured recovery sequence restores blood oxygen and prevents shallow-water blackout.
How to practice
- Surface and tilt your head back to open the airway
- Take 3 large, deliberate breaths before doing anything else
- Do not speak, remove equipment, or swim away until after those 3 breaths
- Signal "OK" to your buddy only after completing them
Practice
Dry Exercises
Choose an exercise and follow the circle. Can be done anywhere — on land, before a session, or as a daily practice.
What it is
Four equal phases — inhale, hold, exhale, hold — each 4 seconds. The symmetry gives the nervous system a steady, predictable rhythm to settle into.
Why it helps
The equal hold phases are the key. They train your body to stay calm during the pause between breaths — the same skill you need when holding your breath underwater. Regular practice lowers resting heart rate and CO₂ sensitivity over time.

Common Mistakes
What to avoid
Mistake
"Hyperventilating before a dive"
Fix
Slow down and breathe normally. The breathe-up should feel calm, not intense. If you feel light-headed, you are overbrreathing.
Mistake
"Breathing from the chest"
Fix
Place a hand on your belly. If it doesn't rise on the inhale, shift your focus downward. Chest-dominant breathing is shallower and more tense.
Mistake
"Rushing the recovery breath"
Fix
After surfacing, many divers immediately talk or move. Always complete 3 full recovery breaths first — every time, without exception.
Mistake
"Practising breath-holds alone"
Fix
Never practise breath-holds in water without a trained buddy present. Shallow-water blackout can occur with no warning. This rule has no exceptions.
