What is free diving? A beginners guide to the sport

Free diving is a type of underwater diving in which the diver holds their breath instead of using a breathing apparatus, such as scuba equipment. It is a unique and challenging activity that requires a high level of physical and mental fitness, as well as specialized training and equipment.

Free diving can be divided into several categories based on the depth and duration of the dive. The most common categories are:

  1. Static apnea: In this category, the diver holds their breath while floating motionless on the surface of the water. The goal is to hold your breath for as long as possible.
  2. Dynamic apnea: In this category, the diver swims horizontally underwater while holding their breath. The goal is to cover as much distance as possible before resurfacing.
  3. Constant weight: In this category, the diver descends and ascends using only their own muscle power, without the aid of weights or fins. The goal is to reach a specific depth and return to the surface.
  4. Free immersion: In this category, the diver descends and ascends using a rope or line, without the aid of weights or fins. The goal is to reach a specific depth and return to the surface.
  5. Variable weight: In this category, the diver descends using a weighted sled or other devices, and ascends using their own muscle power. The goal is to reach a specific depth and return to the surface.

Free diving requires a high level of physical fitness, especially in terms of lung capacity and oxygen efficiency. To prepare for a dive, free divers typically perform breathing exercises and stretching to improve their lung capacity and flexibility. They also practice specific techniques to control their heart rate and conserve oxygen during the dive.

In addition to physical preparation, free divers must also be mentally prepared for the challenges of diving without a breathing apparatus. They must be able to remain calm and focused underwater, even in challenging or stressful situations. Mental preparation often involves visualization and meditation techniques to help the diver remain centered and focused.

Free diving equipment includes a wetsuit to protect the diver from the cold water, a weight belt to help the diver descend, and fins to help the diver swim efficiently. Some free divers also use nose clips to prevent water from entering their nose and goggles to improve visibility underwater.

Free diving can be a dangerous activity, especially at deeper depths. Risks include hypoxia (lack of oxygen), hyperventilation, nitrogen narcosis, and blackout (loss of consciousness due to lack of oxygen). For this reason, it is important for freedivers to receive specialized training and follow safety guidelines to minimize the risks of injury or death.
