Threats That Lie In Boston Scuba Snorkeling

By Lora Jones


Nearly two thirds of the earth is submerged underwater. This represents an entirely new and undiscovered world. The aquatic world is filled with plants, animals, physical features and other parts of nature that most land lubbers do not get the chance to see. The underwater vista is beautiful and filled with coral reefs, multicolored fish, fauna and physical features. The only way to experience such beauty and diversity is through Boston Scuba. However, this extreme sport has a couple of associated dangers that lurk in the water.

Nitrogen narcosis is a scientific term used to describe a severe condition that occurs due to long underwater diving exposure. As divers descends into the depths of the sea, the atmospheric pressure on their bodies and gas increases. This means that the gas contained in the tanks becomes dense. As such, every successive inhalation contains more nitrogen molecules. The diver could become intoxicated with nitrogen and oxygen resulting in disorientation. This results in delusion, mental discomfort and even choking. If not quickly handled, nitrogen poisoning could result in death.

Another effect of increasing water pressure is referred to as the bends. It occurs when an individual ascends quickly back to the surface of water. The body contains pressurized air bubbles and sinuses. The quick decrease in pressure results in expansion of the gases causing intense pain to the individual.

Inexperienced snorkelers have the tendency to hold their breath while in water. Rigorous training and certification courses strictly prohibit this habit. Holding in air could result in bursting of lungs as the diver ascends back to the surface. This is attributed to the expansion of oxygen gas in the lungs as pressure declines.

Not much sunlight and heat reaches the bottom borders of an ocean. This means that water in the lower borders of the ocean is very cold. Where the water temperatures are below the body temperature, heat is drawn from the body. This could result in hypothermia and a host of other cold related illnesses.

Some of the animals that exist in aquatic environments are not so hospitable to human beings. Sharks, sting rays, snakes and some species of fish are known to attack human beings in water. This is a potentiality that cannot be overlooked while diving. For this reason, snorkelers swim in groups or couples in order to look out for each other.

Within the skull and bones are millions of tiny air spaces. As snorkelers increase depth, the rise in water pressure creates a feeling of pain. The ear is most affected due to the presence of the ear canal. The mounting ear pressure could be relieved using a variety of methods referred to as equalizing. This entails pinching the nose, chewing or blowing the nose.

Boston Scuba is a truly wonderful experience that opens up the mind of an individual to new parts of the environment. Nevertheless, this extreme sport should be approached with extreme caution. There are hundreds of schools that teach and provide basic certification for diving. Training is necessary to equip the potential aquanaut with skills for survival in water.
