Undoubtedly, scuba diving is a popular sport across the globe, attracting people of all ages and walks. The beautiful coral reefs, incredible marines plus the eerie shipwrecks are indeed major attraction. As with any adventure sports, scuba diving has a distinctive set of injuries and hazards. In essence, humans are not designed to breath underwater, this implies that each time a diver dives into the water for underwater explorations or scuba diving, then he or she is completely dependent on his equipment and skills for survival. I know, this may sound frightening however the reality is that most perils in underwater explorations stem from dangers posed by faulty equipment plus increased water pressure from the undersea world. Nonetheless, this should not discourage prospective divers into the sport; on the contrary, divers should cautiously approach the sport taking certain safety and health precautions.
One dangerous element of diving is ambient pressure changes known as barotrauma. Barotrauma is usually as result of underwater pressure on the air pockets that are found on the middle ear. In essence, rapid descents may at times be too much to even overcome a diver’s capability to equalize on pressure thus cause pain and injury into the middle ear. Ordinarily, divers attempt to equalize this pressure by deploying a number of tactics all aimed at pushing air from the middle ear. On the other hand, a rapid ascends onto the surface may result in pulmonary embolism. Pulmonary embolism occurs as a result of increased pressure from the undersea environment that results in denser air in the oxygen tank. The resultant effect is that the gas in the lungs expands at equal rate, thus reducing the body’s pressure. As such, a rapid ascent can led to swelling of the lungs. Scuba divers and underwater explorers guide against the same by making slow and controlled ascents while not holding their breath. Decompression sickness is also yet another imminent danger of scuba diving and underwater explorations. Decompression sickness or bends is as a result of increased underwater pressure that results in the body’s tissues absorbing more nitrogen. If the pressure suddenly decreases, then the extra nitrogen forms potential harmful bubbles that may result in skin rash, aching joints, paralysis and even death. Divers, carefully ascent to the surface in controlled movements to ensure that the nitrogen absorbed is released.
Another nitrogen related danger is nitrogen narcosis; this is the consequence of extra nitrogen gas in the body. Extra nitrogen gas in the body is actually hazardous since it cripples sensory judgment as well as perception. Like nitrogen, too much oxygen is also toxic; divers who dive below 135 feet are likely to absorb extra oxygen that may result in nausea, loss of consciousness, seizures and tunnel visions. Apart from increased pressure and air-related problems. Scuba divers are also at a risk of untamed sea life. Sharks are often close to the banks at certain periods, though rare, scuba divers are also at risk of the same. Therefore scuba divers as well as under water explorers should treat sea life with a lot of caution. For the most part, casual scuba divers, unlike other professional underwater explorers, rely on rented equipment from scuba diving operators. A faulty regulator may cause drowning while a damaged depth gauge could cause decompression sickness. Therefore, a scuba diver should at all-time thoroughly check diving equipment either rented or personally owned to avoid potential dangers. Similarly, the risk of hypothermia is also a potential danger of scuba diving, the best way to prevent hypothermia is to utilize proper equipment especially appropriate wetsuits for cold waters.
