This is Don again, coming to you from our San Diego offices in beautiful sunny California. I didn’t want to bore you with a bunch of introductory posts, welcoming all you over and over again like I already did before. So in today’s article, I decided we jump into the deep blue waters of diving. Shall we?
So I am going to start by talking about some very basic diving techniques (that you may have heard of) and those are in regards to when you first try and go into the depth of the ocean or pool. As we know, pressure builds up the lower you go from the surface. So that can cause pain and it can be a great annoyance for your nose and for your ears. So when you do decide to dive, you want to keep your nose shut and try to exhale out of your nose. Obviously you don’t want to do that too hard, because you will blow your ears out. But some gentle pressure on that nose is good, to make sure you are keeping all the pressure of the water to a minimum (at least to a point that it doesn’t bother you.)
Another technique for when you are diving, is to spread your arms open before you and simply try and reach in front of you. This will increase your speed during which you go towards the bottom of the surface. If you just try and swim your way to the bottom of the sea, it will take up too much time. If you are waiting for those oxygen canisters to push you to the ground (because of their weight) well…then you probably may need to wait a while and risk running out of oxygen (kidding of course.) The point is however that you need to help yourself down or else you will be floating on top for ever, never making any diving progress.
As soon as you are down there, to keep yourself there, use your body weight and kick water upwards so that you stay down and levitation doesn’t take you up. While down there, make gentle moves to swim across and to partake in any activity and reason for diving. Always make sure you are paying attention to the pressure watches and oxygen meters to make sure you give yourself enough time to float back to the top (when you need to.) The secret about diving is to be as smooth as possible without jerking your moves nor acting in a reckless way. If you make instant moves or panic, it is very possible that you will make some kind of mistake (maybe disrupt the oxygen transfer mechanism) and that will create a domino effect of panic attacks and mistakes. So it’s just like swimming: you want to be calm and steady, having certainty in every move you make, while making sure you keep mistakes to a minimum.
What happens though when you decide that you are done with your dive and you want to now return to the surface? How do you go about reaching the top of the “ocean sealing?” As you probably have been taught in school, if you go up too fast then your lunges don’t have the time to expand properly (since they had been under pressure in the deep waters) and the bronchial can actually collapse and thus kill you. So one very good technique (old fashioned technique – I’m sure there are more synchronized nowadays) is to let some bubbles float to the top and you should follow right behind, not going any faster than those bubbles. If you go to the surface faster than those bubbles of oxygen, you are risking to have pulmonary problems. So make sure you take your time going to the top, and are allowing your lungs and bronchial system to expand appropriately, as the water pressure decreases towards the top of the surface. In the early days, when they didn’t have any idea of the physiology behind the lungs and the pulmonary system, many divers would be found dead on the shores. So please make sure you take that as an example, and are very careful, in the way you dive and come out of the water. Diving is meant to be something fun, let’s not turn it into a tragedy.
So now you have a small taste of some basic diving techniques. As you can probably tell, we are only scratching the surface here and if you do take any scuba diving courses, there are going to be so many more things we are going to talk about. As I’ve mentioned before, the fun thing about diving is that it connects knowledge from so many other places. So you are going to be learning through the courses, so many things about human health and physiology, in order to prepare for techniques similar to the one mentioned above.
Make sure you e-mail me all your questions. I will be happy to respond to all of them (or at least most of them.) It is really important that you get the concepts straight from the very beginning, so that when (if) you do start, it will be much easier for you. The same way you would strive to be a good student in school, you should strive to know as much as possible about diving (if you are interested of course.) There are so many things that can go wrong, and if there is one thing likely to go wrong: make no mistake as it will happen to you. So the more prepared you are, the faster you will go through the courses and the safest time you will have diving.
Appreciate all of you guys!
