Breath-holding ability, and hence dive performance, is a function of on-board oxygen stores, scope for metabolic rate reduction, efficient oxygen utilization, and hypoxia tolerance. Most divers rely on increasing fitness by increasing click to see more capacity. Some use "packing", which increases lung volume beyond normal total lung capacity. One example is the apnea divlng. This consists of a preparation "breathe-up", followed by a short typically 1 minute breath check this out taken at rest.

Without breaking the hold, participants then begin walking as far as possible dving it becomes necessary to breathe again. Free diving thusa can do close to meters in training this way.

The most obvious hazard is lack of access to air for breathing — a necessity for human life.

Free diving thusa hypoxia is a specific hazard of deeper freedives. This effect can cause hypoxic blackout during surfacing.
