CO2 tables build genuine breath hold tolerance over weeks. Hyperventilating beforehand does the opposite of what beginners think it does, and it has killed trained divers.

A breathing machine pressurised to 198 feet of seawater measures the work it takes to pull air through a regulator. Almost nothing you read online involves one, and the difference is the whole review.

The records look impossible until you learn what the body does when the face hits cold water. Most of the gain is physiological adaptation and relaxation, not lung size, and one record category is not comparable to the others.

Two tables, two different adaptations, and a hard rule about where you do them. One trains tolerance to discomfort, the other trains efficiency at low oxygen, and confusing them wastes weeks.

CWT, CNF, FIM, STA, DYN: a plain guide to how competitive freediving is actually judged, discipline by discipline, and why the letters matter more than the depth alone.

Nitrogen narcosis dulls judgment before a diver notices anything is wrong. Here is why depth impairs decision making, and why self-diagnosis often fails.
May 22, 2024
Coughing pink after a deep dive is not something to shrug off. Squeeze happens when tissue cannot keep up with pressure, and the usual causes are tension, forcing equalisation and pushing depth too fast.
Aug 13, 2026
The old assumption was that one breath cannot load enough nitrogen to matter. Repetitive deep dives with short surface intervals disprove it, and the divers it happens to are usually working, not competing.

Almost every fatality report ends with drowning, which tells you nothing. Investigators use a four-part chain instead: trigger, disabling agent, disabling injury, cause of death. Here is how to read one.

Safety divers, counterballast lines and strict medical protocol turned a high risk sport into one of the most closely supervised in the water.

The current constant weight world records, the athletes behind them, and the federations, AIDA and CMAS, that ratify every metre added to the books.

Falling asleep requires your core temperature to drop, which is difficult when the night does not cool. The fixes that work target body temperature rather than room temperature, and cost very little.

Losing the ability to digest lactose in adulthood is the human default rather than a disorder. It is also a dose problem, which is why total avoidance is usually the wrong response.

Heat, sweat, hard water and relentless sun age a wardrobe faster than wear does. Most of the damage is preventable, and almost all of it comes down to washing habits rather than fabric choice.

Cave diving safety rests on a small set of hard rules built from decades of accident analysis. Here is what those rules are and why the sport enforces them so strictly.

Divers Alert Network is not a training agency and issues no certifications. It collects the injury data, then publishes guidance based on it. Here is that guidance, in the order it matters.

One in five people who live through conflict develops a mental health condition. Most of the useful advice is unglamorous: fix sleep, ration news, keep routine, and treat connection as a necessity rather than a nicety.

Overweighting is the most common equipment error in freediving and the one with the worst failure mode. The rule is simple: neutral at ten metres, positive above it, and the surface is where it matters.

Three minutes at five metres is drilled into every diver and explained to almost none of them. It is not decompression, it is not required, and skipping it is not the emergency people assume.
