Adventure, thrill, and courage — these are the things that define scuba diving. Scuba stands for Self-Contained Underwater Breathing Apparatus. This this kind of diving is the act of swimming under water with the use of self-contained breathing equipment and oxygen tanks. By carrying a source of compressed air, a scuba diver is able to stay underwater for longer periodsof time using simple breath-holding techniques. Scuba diving enables individuals to explore deeper undersea, rather than a few meters under the surface. However, this form of diving also carries with it the risks that other sporting activities possess. Recent studies show that the chance of dying while scuba diving is somewhat higher than boxing and is almost 40 times higher than playing football or water-skiing.
Many of the dangers that this activity posses are associated with pressure. A condition called decompression sickness usually occurs among scuba divers. As a diver breathes air into his lungs at the pressure that resembles that of the depth of water, pressure on his body also increases. The pressure increases rapidly underwater with the pressure doubling every 30 feet. After inhaling from a...
