Dry breath-hold training safety

Updated October 18, 2026

Breath-hold tables are dry training, and done dry, relaxed and within your limits they are a calm way to train. The same exercises done in water, alone or by forcing past your body’s warnings can be dangerous. Please read this before your first table.

Never in or near water

A blackout in water can be fatal within moments, because you can no longer keep your airway out of the water. Tables on breathtable are for dry land only: never in a bath, a pool or the sea — not even shallow water. Breath holding in water belongs in a freediving course, with a trained buddy or instructor watching you.

Don’t train alone

Blackouts can happen without warning, even on dry land, and lying on a bed or mat does not remove that risk. Have someone nearby who knows what you are doing, especially for O2 tables and PB attempts.

Lie down, and never practise standing

Sit or, better, lie somewhere you can’t fall. Never do holds while standing, walking, driving or anywhere a sudden loss of consciousness could hurt you: a standing blackout causes a hard fall.

Don’t hyperventilate

Between holds, breathe at normal volume with long, easy exhales. Fast or deep over-breathing lowers your CO2 and delays the urge to breathe — the early warning that you need air. It makes blacking out without feeling it coming more likely.

Stop at the first warning signs

End the hold and breathe if you notice any of these:

dizziness or light-headedness
tingling in your lips, fingers or face
changes in your vision
your jaw clamping or shoulders tightening
unusual tiredness, confusion, or feeling unwell

Ending a hold early is the right call, not a failure. breathtable’s “Breathe now” button is always on screen during a hold.

Keep sessions short and calm

Steady, moderate sessions work better than intense, irregular ones. Advice on frequency ranges from one table a day to a few sessions a week; either way, don’t stack tables back to back, and give yourself rest days.

Check with a doctor first if it applies to you

This site gives general information, not medical advice. If you have a heart, lung or blood-pressure condition, epilepsy, are pregnant, or take medication that affects breathing or heart rate, talk to a doctor before breath-hold training.

Learn from an instructor

Tables are a supplement to proper training, not a replacement for it. A freediving course from an agency such as AIDA, Molchanovs, SSI or PADI teaches safety, buddy procedures and rescue in person — the things a website can’t.
