[deep thinker]

Easy dont breathe . On the serious side, Ive always hyperventilated, allthough I didnt know it at the time and then before I go under pack as much air into my lungs as possible not knowing either of these could be dangerous untill I did a freediving coarse and got taught how to pack should I so wish and also got warned against hyperventilation. Now what I do before a dive is lay completely motionless on the surface while breathing like I would normally in a relaxed environment and before I go down breathe out one last time and breathe in normally and just hold it, I never really think about it and never feel dizzy or hypoxic after I come up. I also find it difficult to put my breathe up pattern into words because of the amount of thought I spend on it, so maybe a good idea would be to do a freediving coarse where you can experiment with different techniques under professional supervision
