Physiology of Freediving

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.

I know I know, it’s been such a very long time since you heard from guru of freediving physiology and darling of riverbank critters, the world-famous Dr Otter.

The mammalian diving reflex is a unique set of evolutionary adaptations that are left over from the time when all life developed in the oceans.

Breathing is a multistage biological process that is designed to move air in (inhalation) and out (exhalation) of the lungs.

A wise man once told me “there are two kinds of divers in this world: those who pee in their wetsuits, and those who lie about it…” but is this actually true?

So far, competition organisers have responded to the tragic death of Nicholas Mevoli in 2013 by looking for ways to exclude divers who seem to be at ri
