The Dangers of Diving

People with a hunger for excitement are often taking on one
adventure or other. Be it rock climbing or shooting down
the rapids in a canoe along some river, they constantly
seek out physically demanding activities and even danger.
Most of the potential dangers may be averted through
adequate preparation and training.

One of the most alluring and potentially frightening
activities sought out by many is underwater diving. This
can take the form of scuba diving or snorkeling, each of
which requires its own set of equipment and instructions.
Scuba diving can take top-notch swimmers into the depths of
the sea by equipping them with oxygen tanks and a wet
suit. Snorkeling allows competent swimmers to explore more
shallow areas, such as a reef. In either case, extreme
caution is required.

The loss of oxygen is probably the biggest danger because
should a scuba diver become damaged or even lost in the
sea, a race to the surface is the only means of avoiding
drowning. Snorkelers also must worry about an unexpected
loss of air supply and need to make a made dash to a boat
or shore. Making certain that the tank functions properly
and constantly monitoring it while submerged are vital for
scuba divers because a simple kink in the air line can
spell disaster while under water.

Another danger to be careful of for divers is the bends.
Submerging or surfacing too rapidly are the cause of this
condition in which higher-than-normal levels of oxygen
enter into the bloodstream and wreak havoc on the
circulatory system. The bends can be deadly if they are
not properly tended to immediately. Always bring a diving
buddy along and it would also be a good idea to keep
someone in the boat above while diving so they can get help
in the event of an emergency.

Some consider the biggest threat, if not physically then at
least mentally, to be the presence of man-consuming sharks
like the feared Great White. With several recorded at
lengths exceeding 20 feet and a history of attacking people
and causing dismemberment, severe bleeding, and even death,
it is no wonder why they are so feared in the diving
community. This is why it is a very good idea to stay away
from known feeding grounds of sharks. There are other
creatures whose defensive sting is something to be avoided
such as that of the jellyfish or eel.
