During freediving, a diver must breathe through his or her mouth without having air in their lungs. In addition, a diver must be able to swim several meters underwater without pre-existing conditions.
Freediving is a very competitive sport. The competitive freediving community has a very low death rate. This is because the competitions are well-organized and the people involved are highly professional.
Freedivers must be trained to stay safe and avoid mistakes. They must also have a diving buddy. If they cannot resurface, their buddy will bring them to the surface.
Freedivers who go alone are at a high risk for death. They should not freedive without a buddy. Having an experienced partner is the best way to avoid deaths.
A freediver is at risk for brain damage if he or she does not know how to dive or how to track depth. Most freedivers do not know this. They may have a blackout while diving. However, most blackouts can be handled. Most blackouts occur in the top 15 feet of the water column.
One of the biggest risks is low oxygen levels. The body’s oxygen level must fall below a certain level to trigger a blackout. The body’s lungs try to compensate for the low oxygen levels by diverting blood from the extremities to the vital organs. The body does this by slowing down its metabolism.
A freediver may also suffer decompression sickness, which can be very painful. This condition can occur when a diver dives deeper than 85 feet.
