You can’t fake it in freediving: if you’re nervous, agitated or emotional then your body’s organs will consume more oxygen - especially the brain, which consumes 20% of our oxygen at the best of times. When you only have one lungful of air, and that air is only 1/5th oxygen, every molecule counts! That’s why being in control over thoughts, emotions and everything that happens internally in the body and mind is paramount. These same techniques can be applied in everyday situations, to maintain equanimity in the face of the greatest obstacles that life throws at us. Follow the link in my bio for more info.
