Well the first thing you must be aware of are the dangers of breath hold diving (free diving).

Basically the more efficiently you use your oxygen (O2), the longer it will last. The fitter you are, the more efficiently your body will use its O2 supply. The more relaxed you are and the less energy you use, the slower your heart will beat, so again, less O2 used. Yoga is good for this and teaches you breathing excercises.

There's also a psychological aspect - can you resist the urge to gasp for air when your body tells you to? This is caused by hightened levels of Carbon Dioxode (CO2) in your body. Although you can ignore this urge, it is a natural defence to stop you asphyxiating.

You may hear talk of hyperventilating before a free dive - but do this too much, and you will lower your CO2 levels so much that when you need O2, your body won't have enough CO2 to tell you! This can lead to death!

I would suggest if you want to take this seriously, you take an intro into free diving with a registered free diving school.

Above all, dive safe and don't dive alone!
