What Is Scuba Diving?

 Diving is one of the fastest-growing industries, attracting millions of people every year. What attracts every diver to enjoy this free time every day is the adventure, the feeling of exploration, and the variety of colorful corals and other marine life.

We started diving a long time ago. The word diving refers to swimming underwater, and the word diving is short for "scuba," and it has become acceptable to refer to diving as "equipment" or "device." Therefore we understand the word diving as swimming underwater with special equipment.

Many people think that gas divers breathe oxygen while diving. Oxygen is Although the human body needs oxygen to survive, pressurized oxygen can be toxic. The gas used by divers is, therefore, normal compressed air. Air consists of 78.084% nitrogen, 20.946% oxygen, and 1% other gases with little or no effect when compressed air is inhaled.

High-pressure nitrogen can temporarily affect our nervous system and disrupt signal transmission, causing what is known as anesthesia at greater depths (30 to 40 meters or more). Nitrogen has effects similar to alcohol (loss of decision-making ability, loss of concentration, poor judgment, multitasking, and coordination).

The easiest way to avoid nitrogen anesthesia is to have a diver limit the depth of the dives. In the case of anesthesia, the effects disappear almost immediately when you climb to a shallower depth.

In addition to its narcotic effects, nitrogen is another problem. Under pressure, nitrogen dissolves in body tissues and begins to accumulate. This should be kept within limits to prevent nitrogen from leaking out of the solution and forming bubbles in our bodies known as "decompression sickness" or "cornering" when all of the nitrogen's pressure is released to the surface.

To avoid curves, divers should slowly minimize the water pressure on their bodies at the end of each dive. This allows gases trapped in the bloodstream to remove the solution and leave the body gradually. It does this by slowly ascending and making safety stops or decompression stops using dive computers or decompression tables as a guide.

As you can see, when diving, divers are limited in time and depth due to the nitrogen in the air. Thanks to new technologies, we have succeeded in pushing our limits today. Different gas, training, and equipment are required for divers over 40 meters and divers who spend much time underwater.

The depth limit for recreational diving is 30 to 40 meters, but it also depends on the formation and the gases used underwater. Nuno Gomes (South Africa) currently holds the world record for deepest diving with scuba equipment. The 318-meter dive broke the late John Bennet's previous record of 308 meters (confirmed). The total diving time was 12 hours and 20 minutes, while the descent was 14 minutes. The French diver Pascal Bernabé claims to have dived 330 m in July 2005 (unconfirmed). Previous records were set with "recreational" diving. Commercial divers can reach depths above 500 meters using specialized commercial and military diving equipment and support systems.

It is important to remember that underwater has its limits and risks that professional divers like to take. And don't forget that recreational diving is for fun. Dives between 5 and 20 meters can show you the fantastic world once explored by Cousteau. These depths have the advantage of providing divers with better light, colors, and marine life. Also, you breathe less air from the tank during shallow dives, making your dive longer and safer.
