Hyper ventilating and breathing?

[Clover]

What sort of techniques and methods are used for hyperventilating to increase the time you can hold your breath.

How do you achieve this, what sort of things should i be looking out for, i.e. heart rate lung capacity? are there any apparent dangers?

Any advice would be good.

Hello Clover,

Welcome to the forum. Hyperventilation, is definitely the killer number one of recreational freedivers, and spearos, and is to be aovided by all means. The two main risks of hyperventilation is that it suppresses the urge to breath, while in the same time decreasing the hypoxic tolerance, which means that you blackout sooner than you would normally, and in plus without seeing it coming. Please look up more details in the archive - it is a frequently discusse topic, so you can find much more detailed information in the archive. For example here:
