Freediving is often described as a conversation with your body — and breath control is the vocabulary you need to speak it fluently.
Most beginners arrive at their first session trying to "hold" their breath by tensing up. This is the single biggest mistake. Tension consumes oxygen rapidly and triggers the urge to breathe long before your body actually needs to surface. The goal is the opposite: complete relaxation.
The Diaphragmatic Breath Before you even think about the water, practice breathing from your diaphragm rather than your chest. Place one hand on your belly and one on your chest. Inhale slowly through the nose — your belly should rise first and your chest barely move. Exhale fully, letting the belly fall. Practice this for five minutes every morning.
The Pre-Dive Breath The final breath before a dive is not about inhaling as much air as possible. Our coaches teach a technique called "breathing to 80%" — a calm, full breath that fills the lungs without straining the chest. A forced maximal inhale creates tension in the intercostal muscles that actually shortens your dive time.
Packing: A Skill to Learn Later You may have heard of "lung packing," where divers use the throat to push extra air into already-full lungs. This is an advanced technique that carries real risks — throat barotrauma and blackout — if practised without proper coaching. We do not teach it at the beginner level and recommend against self-learning.
The First Sign to Surface Our most important rule: when you feel the first strong urge to breathe, you should already be ascending. That urge is caused by rising CO₂ in your blood, not by lack of oxygen. With practice, you will learn to distinguish the early signal from the later diaphragm contractions — and you will use the former as your cue to end the dive while you still have plenty of oxygen left.
