Underwater diving is definitely one of the activities sought by such
adventure-seekers as it can be both exciting and dangerous. Snorkeling and
scuba diving are the two varieties of diving available to people and each
comes with its own specialized equipment and necessary training. A wet suit
and an oxygen tank allow expert swimmers to experience the depths of the
sea. Shallow areas such as reefs are accessible to snorkelers, who also must
be great swimmers. Extreme care is necessary for either activity.
The greatest concern is perhaps the loss of oxygen. If a scuba diver's
air tank empties quickly or becomes damaged or lost, that person must return
to the surface promptly to escape drowning. Someone who snorkels likewise
might be cut off from his or her air supply, requiring an emergency return
to the boat or shore. It's important to make sure the air tank works
properly before going underwater and then to monitor its workings while
hooked up. Even something as minute as a kink in the hose can present
danger.
Another possible complication for deep-sea divers is getting the bends.
This is when the person submerges or surfaces too quickly, moving through
several feet of water at a rapid pace. High levels of oxygen can enter the
bloodstream and create problems for the circulatory system. If not treated
promptly, the situation can become life threatening. Always take a partner
and preferably have someone manning the boat while you are underwater, so in
case of emergency, you can get immediate aid.
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.
