Freediving was practiced in ancient cultures to gather food, harvest resources such as sponge and pearl, reclaim sunken valuables, and to help aid military campaigns. The divers faced the same problems as divers today, such as decompression sickness and blacking out during a breath hold. In ancient times freediving without the aid of mechanical devices was the only possibility, with the exception of the occasional use of reeds and leather breathing bladders.

There are also a range of "competitive apnea" disciplines in which competitors attempt to attain great depths, times, or distances on a single breath. Underwater diving without breathing apparatus A freediver on the ocean floorįreediving, free-diving, free diving, breath-hold diving, or skin diving is a form of underwater diving that relies on breath-holding until resurfacing rather than the use of breathing apparatus such as scuba gear.īesides the limits of breath-hold, immersion in water and exposure to high ambient pressure also have physiological effects that limit the depths and duration possible in freediving.Įxamples of freediving activities are traditional fishing techniques, competitive and non-competitive freediving, competitive and non-competitive spearfishing and freediving photography, synchronised swimming, underwater football, underwater rugby, underwater hockey, underwater target shooting and snorkeling. ![]()
