Scuba diving is undoubtedly a world-renowned recreational sport. Eerie shipwrecks and beautiful coral reefs across the globe have become huge tourist attractions. However, you should nev3er forget that scuba diving is also considered an extreme sport, requiring hours of training and a scuba diving license. It comes with life-threatening hazards and peculiar injuries. Most scuba diving dangers come from the increase in water pressure, but you will also find danger through faulty equipment and sea life.
This is caused by an increase in water pressure that occurs on the air pocket within the middle ear. Although divers can equalise their ears by pinching their nose and blowing, by swallowing or by chewing to provide more air to the middle ear, there is still a possibility to cause injury or severe pain when descending too rapidly.
This is caused by an increase in water pressure which causes the tissues of the body to absorb more nitrogen. Once the pressure is rapidly reduced, the extra nitrogen can potentially form harmful bubbles. You will need to return to the surface in various stages, often following the air bubbles around you. Decompression sickness can range from a skin rash or aching joints to paralysis and even death.
The extra nitrogen in your body can also cause danger while scuba diving. Those that had nitrous-oxide gas while visiting the dentist will already be familiar with this. Nitrogen narcosis can impair sensory perception and judgement.
This is usually a danger for those that decide to dive below 135 feet. Similar to nitrogen, your body will absorb additional oxygen due to an increase in water pressure. This is not a problem for most, but when you dive at extreme depths, you’ll absorb so much additional oxygen that becomes toxic. The dangers include seizures, loss of consciousness, twitching, nausea, and tunnel vision.
This is another risk a diver faces when ascending to the surface too quickly. The increase of water pressure will result in the gas your breath becoming denser due to the fact that gas is essentially crammed into the same space while under pressure. Your lungs will expand due to the gas it holds at the same rate the body pressure is reduced, so an ascent at a rapid pace will cause your lungs to either swell or pop. Ensure you make slow and controlled ascents and to never hold your breath.
Scuba diving is basically entering an untamed environment. While most sea life is not considered aggressive, incidents to occur and you can’t afford to forget that you’ll be surrounded by wild animals. Steve Irwin, the famous television wildlife host, was killed by a stingray when he was stung through his chest, and this is usually a harmless sea creature that you’ll frequently encounter. Therefore, its best that you never touch an animal undersea and this includes coral as well. This will protect both you and the sea life you are admiring while diving.
