Scuba diving is slowly becoming one of the most popular adventure sports. There are two reasons behind this. First, it will make your introduction to the underworld, the whole new world below the sea surface and secondly, you don’t have to be a swimming expert to be a diver. Millions of people make their introduction to scuba diving every year to get their diving license done.
The Technical points of scuba diving:
Humans are always attracted by the unattainable. It’s human nature to know the unknown, be it space or the undersea world; the areas which are not entirely in our control. As we are not able to breathe underwater, Scuba diving gives us a brief opportunity to explore the world under the sea.
Scuba is the abbreviation for Self Contained Underwater Breathing Apparatus, which means equipment to help breathe underwater. To dive underwater, the diver has to dive with a tank of compressed air which contains a mixture of nitrogen, oxygen and some other gases as well.
Some people believe the air tank contains pure oxygen, which is not true. If we breathe pure oxygen, our body will suffer from oxygen toxicity. As the compressed air contains nitrogen, the divers should be very careful about the depth and should keep a track of the time elapsed while diving underwater as breathing from the compressed air containing nitrogen may lead to nitrogen narcosis.
Apart from nitrogen narcosis, another serious condition called decompression sickness or Caisson’s disease can develop. In this condition, nitrogenous bubbles are formed within the diver’s body. It can be fatal when the diver returns to the normal air pressure at the surface.
Know what to do and what not to do while diving:
1. Don’t touch anything while diving. It may be tempting to touch a coral or pick up shells but avoid the temptation to do that. Be a responsible diver.
2. One skill that every diver should master is the buoyancy skill. To be safe from nitrogen toxicity a diver should be able to go up and down in the water. To master the buoyancy skill, all one has to do is practice and practice a lot.
3. Learn to control your fins as moving the fins in an improper way can disturb the underwater habitat. If you hit something with the fins, look at it, and try to take a hand stroke to move away. Spend some time practicing your finning techniques to be a good diver.
4. Most important of all, never forget to monitor your air and do it as often as you can. Watching over your tank will buy you more diving time if you do it properly.
5. Be relaxed while you are underwater. The more uncomfortable you are, the more air you will use. So be relaxed and hold still and use your fins to move forward. Use big and moderate fin kicks to spend as less energy as possible. And you will find yourself buying more time underwater.
6. Don’t wear unnecessary diving accessories. Carrying the extra load would only drag you down and will increase the air consumption.
7. It is very tempting to go deeper. But never exceed your limit. Go as deep as your body could permit. Challenging your limit could cause you to suffer from depression sickness or Caisson’s disease, which in turn could be fatal.
8. Be confident about the dive and never follow peer pressure. Only you could know what is right for you and always try to follow your brain.
9. Watch where you are in the water. If you are following someone or someone is following you, don’t get too close, as you both can get hurt by each other.
10. Be choosy about your diving gears and never forget to take care of it. As these are the types of equipment that are going to save your life. If possible, think about the environment and choose the kind of gear which has minimized effect on the environment. Nowadays many dive watches are available which has a futuristic battery-less operation as they get charged by light or movement.
11. Follow every word of your diving instructor like the Bible. If you are not paying attention to your guide, you can end up getting lost.
12. Some diving instructors follow a rule to keep the ocean as clean as they can do. The rule goes by the name of “one dive, one piece of debris”. With every dive, everyone going underwater has to pick up a piece of garbage found underwater. If every diver follows the rule, the garbage island in the Pacific Ocean will clear up very soon.

Be aware and pay attention to where you are in the water. The more you dive, the more you would get comfortable under water: and the more you get comfortable, the lesser air you use. Act in the very way you want others to act. Be a good change to the environment and step up to become a responsible and sustainable diver. Take care of your safety measure and experience at the fullest.
