All year round, diving is a popular activity. It is basically defined as the act of entering the water and stay below the surface to explore, work, than just simply have fun. Diving There are several famous dive sites around the world. The diving is not limited to the oceans, however. Many divers submerge in other forms water such as lakes, ponds and rivers.
Scuba refers to the tank containing the air that divers carry with them so they can breathe underwater. Diving word means "autonomous underwater-breathing apparatus.
For centuries, people have been fascinated by the life found underwater. In fact, there are an estimated six million active divers worldwide. Commercial, cave, ruin and military diving are just some purposes for diving. The most popular of which is sport or scuba diving.
However, before going to dive, there are several issues to consider. Scuba diving is potentially dangerous sport. Therefore, it is necessary to observe some their physiological concepts to help familiarize.
Scuba diving requires special training, especially if you intend to go over 130 feet below surface. Because the water pressure, which is suffering from decompression sickness and air embolism.
It would also be useful to know that a person tends to consume more air that goes deeper underwater. It follows that, with the same amount of air, the divers to a depth last longer. In addition, the air consumption varies for each person, depending on your dive experience, general relaxation and fitness. Furthermore, those who have a style healthy living, which means less consumption of alcohol and snuff, expected to last longer under water.
The dangers in diving risks arise primarily from physiological. Unlike aquatic animals have gills to extract oxygen from water, human beings need external devices to breathe underwater. Thus, is important strictly follow the procedures learned during the certification process of scuba diving. You should never try to dive beyond their skills and experience.
To breathe comfortably underwater, it takes more than good air supply. You need to consider the water pressure in the chest and lungs. That means that you should be able to exert enough pressure to inhale to meet the temperature, or otherwise not be able to inflate safely to his lungs.
Fortunately, there are modern devices such as regulators of the valve to ensure that the diver can breathe naturally and almost effortlessly under the water regardless of depth. You will not use your nose to inhale, as it is often encapsulated in a diving mask. However, no need to worry because the inhalation of the mouthpiece of the regulator will come spontaneously.
It is also important to ascend or descend slowly, to give your body enough time to equalize pressure. Sudden changes in water pressure can be very harmful. A significant difference in pressure and outside the diver can cause serious injury, called barotrauma.
Elbows or decompression sickness is caused by staying too long at great depths, then rise rapidly. The deepest diving submarine, the denser the air we breathe, allowing it to breathe nitrogen than the safe amount. The nitrogen forms tiny bubbles in the bloodstream and tissues. If these bubbles are trapped inside your body, which can explode and cause extreme pain.
Other fatal injuries related to the pressure is air embolism. When it gets too fast, the blood gas forms a large bubble size that can impede blood flow to his brain. To allow the excess air to escape from the body, a diver must ascend slowly enough.
To avoid these risks, you should be able to calculate how long it can remain safely at a given depth and time to be diving again. Of course, there is also the risk of running out of air and breathing polluted air when underwater. Scuba certification courses to be taught how to avoid these and what to do if an experience diver companions of those problems.
So before you explore the underwater world, make sure you have passed a certified diver. This will allow to dive without supervision, to fill their air tanks and buy scuba diving equipment. Of course, when you go scuba diving, make sure you have someone with you who can help if something goes wrong.
