History of Freediving
Freediving, also known as apnea diving, is an ancient practice that dates back thousands of years. It was initially used as a means of catching food, harvesting resources such as sponges and pearls, and reclaiming sunken valuables. The island of Kalymnos was a central center of diving for sponges.
Over the years, freediving has evolved into a competitive sport and a test to see what the human body is capable of. The sport has been gaining popularity worldwide, with countries such as Greece, Italy, and Japan leading the way.
Historically, freediving has been an important livelihood in some cultures. The Bajan people, also known as the “Sea Gypsies of Malaysia,” fish underwater for up to five minutes at a time. During the Peloponnesian War, divers were used to get past enemy blockades to relay messages as well as supplies to allies or troops that were cut off. In 332 BC, during the Siege of Tyre, the city used divers to cut the anchor cables of Alexander’s attacking ships.
Freediving has come a long way since its early days, with techniques and equipment advancing to allow for deeper and longer dives. Today, freediving is a popular recreational activity, with many people taking up the sport to explore the underwater world and push their limits.
Freediving Disciplines
Freediving is a sport that involves diving underwater on a single breath of air. It is a challenging and rewarding activity that requires a high level of skill and training. There are several different disciplines of freediving, each with its own unique set of challenges and requirements.
Static Apnea
Static apnea is a discipline in which the diver holds their breath for as long as possible while remaining motionless in the water. This is typically done in a swimming pool, and the diver will float on the surface or stand on the bottom of the pool with their face submerged. Static apnea is a great method of training for other freediving disciplines and can help improve lung capacity and breath-holding ability.
Dynamic Apnea
Dynamic apnea is a discipline in which the diver swims underwater on a single breath of air. There are two variations of dynamic apnea: with fins and without fins. In both variations, the diver must swim as far as possible before resurfacing.
Constant Weight
Constant weight is a discipline in which the diver descends and ascends using their own power without the use of weights or other devices. The diver must carry all of their equipment with them during the dive, including fins, mask, and wetsuit.
Free Immersion
Free immersion is a discipline in which the diver descends and ascends using a rope or line. The diver pulls themselves down and up the line using their arms and legs. This discipline is typically used for training and can help improve overall diving technique and strength.
Variable Weight
Variable weight is a discipline in which the diver descends using a weighted sled or other device and ascends using their own power. This discipline allows divers to reach greater depths than constant weight diving.
No-Limits Apnea
No-limits apnea is a discipline in which the diver descends using a weighted sled or other device and ascends using a lift bag or other device. This discipline allows divers to reach the greatest depths of any freediving discipline.
Each of these disciplines requires a high level of skill and training, and divers must adhere to strict safety protocols to ensure their safety while diving.
Physiology of Freediving
Freediving is a form of underwater diving that relies on breath-holding until resurfacing rather than the use of breathing apparatus such as scuba gear. The human body is adapted for breath-hold diving in so many miraculous ways that, once you start looking, it’s not hard to believe that this is something we’re absolutely meant to do. In this section, we will explore the physiology of freediving, including the mammalian dive reflex, breath-holding techniques, effects on the body, and equalization techniques.
Mammalian Dive Reflex
The mammalian dive reflex is a phenomenon that occurs in all mammals, including humans, when they are submerged in water. It is an automatic response that helps the body conserve oxygen and survive underwater. When the face is submerged in water, the body’s response is to slow down the heart rate, reduce blood flow to non-essential organs, and constrict blood vessels in the extremities. These responses help to reduce the body’s need for oxygen, allowing the diver to hold their breath for longer periods.
Breath-Holding Techniques
Freedivers use a variety of breath-holding techniques to extend their time underwater. One common technique is to take a series of deep breaths before diving, known as “purging.” This helps to oxygenate the body and remove carbon dioxide, allowing the diver to hold their breath for longer. Another technique is to exhale slowly and steadily during the dive, which helps to reduce the build-up of carbon dioxide in the body.
Effects on the Body
Freediving can have several effects on the body, both positive and negative. One positive effect is that it can help to increase lung capacity and improve overall lung function. It can also help to improve cardiovascular health by strengthening the heart and reducing the risk of heart disease. However, freediving can also be dangerous if not done properly. One of the biggest risks is hypoxia, which occurs when the body does not receive enough oxygen. This can lead to unconsciousness and even death.
Equalization Techniques
As a freediver makes their descent into the sea, the pressure on the outside of the eardrum increases, and as a result, the eardrum is pushed inwards, often painfully. The diver uses “ear pressure equalization” techniques to force air into the middle ear to “equalize” the pressure at both sides of the eardrum. One common technique is the Valsalva maneuver, which involves pinching the nose and blowing gently. Another technique is the Frenzel maneuver, which involves using the back of the tongue to push air into the middle ear.
In conclusion, freediving is a fascinating and challenging sport that requires a deep understanding of the physiology of the human body. From the mammalian dive reflex to equalization techniques, there is a lot to learn about how the body responds to the underwater environment. By understanding these processes, freedivers can stay safe and enjoy the incredible experience of exploring the depths of the ocean.
Freediving Safety and Education
Freediving is a sport that requires a high level of physical and mental preparation, as well as proper safety measures. The following subsections outline the most important aspects of safety in freediving.

A buddy can assist in case of an emergency, and can also monitor the freediver’s vital signs and physical condition. Buddies should be evenly matched and familiar with safety and rescue procedures. The safety diver should watch the dive line for the freediver, who must follow it at all times.
Risk Management
Freedivers must understand and follow proper safety guidelines to minimize risks. One of the most important guidelines is to know one’s limits, particularly when it comes to depth and pressure. Freedivers should also be aware of the risks of hyperventilation, which can lead to shallow water blackout. It is important to always dive conservatively and to never push oneself beyond one’s limits.
Emergency Procedures
Despite taking all necessary precautions, emergencies can still occur during freediving. Freedivers need to be familiar with emergency procedures, including how to perform rescue breaths and how to administer first aid. It is also important to have a plan for contacting emergency services in case of an emergency.
Safety Equipment
Using appropriate safety equipment can also improve safety in freediving. Freedivers should always wear a wetsuit to protect themselves from hypothermia, as well as fins and a weight belt to aid in buoyancy control. A dive computer can also help monitor depth and time and can provide valuable information to help avoid risks.
In conclusion, safety is a top priority in freediving. By following proper safety measures and guidelines, and by using appropriate safety equipment, freedivers can minimize risks and enjoy a safe and enjoyable experience.
