Some Interesting Facts About Scuba Diving
The first fact about scuba diving one needs to know is that the word scuba is really nothing but an acronym for the phrase "Self Contained Underwater Breathing Apparatus". Scuba diving is made possible by using high pressure metal tanks that are attached to the back of the diver and air supply is regulated through a regulator breathing device which allows the diver to independently swim in deep waters. There is also special apparel used for scuba diving such as wetsuits, gloves, and hoods in conjunction with supporting equipment like computer watches and buoyancy control.
Another fact about scuba diving is that concerning anyone who wishes to become a scuba diver. There are over one million people who obtain scuba diving certifications worldwide, each and every year.
Scuba diving basically necessitates the diver to put on a heavy tank that is full of compressed air on the back and dive deep into the water and the small rubber tube is the only link that helps keep the diver stay alive, underwater. Another fact about scuba diving is that, to become a scuba diver one should first of all be serious and decide whether to dive in warm water or the more hardcore cold waters or would shipwreck explorations be more interesting. In some instances, there would also not be any need of obtaining prior certification in order to go scuba diving, especially in the resort dives found in the Caribbean, Acapulco as well as Florida Keys. Here they will offer one day crash courses in diving that do not result in certification.
For those who have more interests in diving and need certification they should know all about the physical as well as mental aspects about this sport before proceeding further. The physical considerations that need to be known are swimming ability, breathing ability and equalizing ability.
Your first concern should be whether you feel confident about being physically able to scuba dive. This would mean knowing whether you can swim and in case the answer to this question is negative then scuba diving should not be more than just a hobby for you. Another fact about scuba diving concerns the fact that since scuba diving is tiring, overweight people, or those with diabetes, heart conditions or any other ailments such as predisposition to drowning should consult a doctor before attempting to scuba dive.
One more important fact about scuba diving is that since scuba diving involves breathing through the mouth instead of the nose one should have had enough experience in breathing through the mouth before scuba diving. A more pertinent fact about scuba diving relates to equalizing the pressure within the ears as one goes deeper down into the water. This in effect means knowing how to "pop" the ears just like it is done on an airplane. Since pressure builds when descends deep into the water one needs to be able to pop the ears and for learning how to do so one should consult a doctor or scuba instructor.
