Interesting Facts You Might Not Know About Diving
Diving is one of those past times that for those who fall in love with it, can never seem to get enough! Any diver knows that it is not just about what you see when you take the plunge into the depths. It’s about the sense of freedom, like the weight of the world has been lifted. Every time is like the first time and many can agree that diving is without a doubt an addictive adventure.
Each diving destination, whether it is in South Africa, Mozambique, Australia or anywhere else in the world, has its own uniquely interesting facts and tremendously exciting things to see. But the act of diving itself is also quite fascinating.
Facts about Diving
- When divers reach a depth of 10 meters and below, it becomes next to impossible to see the colours red or yellow. This means that if you were to somehow cut yourself while at this depth, your blood would look quite blue.
- The word “scuba” is not something made up with no meaning. Instead, it stands for “Self-Contained Underwater Breathing Apparatus”.
- There is such a thing as feeling drunk while diving. It is called oxygen narcosis and it has been known to affect most divers at some stage of their diving. It will generally happen when Nitrogen is breathed in at depths below 25 meters.
- Sound actually travels quickly when submerged. In fact, it can travel 5 times faster than when above waters. This makes it just about impossible to determine exactly where the sound is coming from which is why sound is not something divers can safely rely on.
- Each year, between 8 and 12 people will be killed by sharks. This sounds quite alarming right? Well actually, it is a drop in the ocean, pardon the pun, when you consider that humans are responsible for killing well over 30 million sharks annually.
- When under pressure, oxygen can become toxic. For this reason, if divers are going down to distances of more than 42m, they will use special gases with lower concentrations of oxygen.
- Diving injuries, although quite rare, do happen. When officially recorded, they are called “barotraumatic injuries” but these generally refer to broken noses or fingers. Often, these injuries don’t even happen in the water, instead they happen while getting into or out of boats and tanks or weights connect with a diver.
- The intense colours of the underwater world, as seen in documentaries or underwater photographs are not always a real representation of what is to be expected. This distinct lack of colour is due to the fact that water quite quickly absorbs light and the one colour that disappears the fastest is red. Professional photographers and documentary film makers will often use filters to counteract the effects of the light, giving viewers a distorted idea of what the underwater world looks like.
- Scuba diving is listed as a risky sport but the facts show that only 1 in 211 864 dives will result in a death.
