For many, breathing is an essential component in their method for remaining calm. But how do you keep composed when deep underwater with no oxygen, for up to seven minutes? How do you push yourself to your limit without going too far?
Freediving is a form of diving without the use of any breathing apparatus. Competitors can specialise in a range of disciplines in both deep diving and pool diving. I caught up with five British freedivers to find out why they chose this underwater sport and learn how they value safety in the sport.
