Static Apnea and Diving Reflexes

Goran Čolak set a Guinness World Record in 2014 by holding his breath for 23 minutes using static apnea, a technique where one holds their breath underwater without moving. This feat involves overcoming the discomfort caused by excess carbon dioxide rather than a lack of oxygen. Čolak uses visualization techniques, oxygen saturation, and cardio training to prepare. The mammalian diving reflex, which slows the heart rate and conserves oxygen, plays a crucial role. However, attempting such feats without understanding one's limits can be dangerous.
