For many people, one of the major attractions of Freediving is its technical aspects. The human body is adapted for breath-hold diving in so many miraculous ways that, once you start looking, it's not hard to believe that this is something we're absolutely meant to do. Freediving physiology is a fascinating subject, and a growing area of interest amongst the scientific community. More importantly, a solid understanding of mechanisms like the mammalian dive reflex, Boyle's Law and Archimedes' principle is essential for anyone interested in improving their breath-hold and freediving ability. Here at Freedive-Earth we take contributions from medical professionals and scientists which are freely available to you.
