There are people who like swimming in seas but are not content with doing only this and they want to dive deep underneath. This enables them to see various beautiful corals and sea animals living there personally instead of just through images or videos. Having this experience is like discovering many things that most people cannot see.
There are many places you could dive which offers spectacular views to those capable enough to do so. Examples of these are the areas considered as top diving in the Keys where it also has some ship wrecks aside from the usual things you can see underwater. There are different choices depending on your expertise and how deep you are able to go.
If you want to try this and know if ever you have what it takes for this activity then attend some scuba diving classes available in resorts. The equipment necessary would be provided by them and you will be taught how to use them properly including some basic skills. After you may go to the ocean for a test dive together with an instructor.
Be sure you are healthy and does not have breathing problems, sinus infection and other significant condition or illness which compromises your health. If you unfortunately do then postponing your first undersea adventure is best until you feel better for this. Having issues in your sinus could place enough pressure in your ears which is uncomfortable even in twenty to thirty feet deep.
Only go when you feel healthy and you must be in a reasonable condition as well as feel comfortable to be in open and wide bodies of water. You should be capable to swim physically obviously and if you have sea sickness, take medication starting at least twelve hours before the boat trip. This enables the medication to get inside the blood stream and be more effective.
Relax and do not let the adrenaline of going into alien environment, wearing a rubber suits and handling strange hardware get you. An experienced, licensed and trained diver will lead you who has dived there many times than you might count. You breathe more quickly when you are over excited or anxious which makes your trip short due to your oxygen supply being used rapidly.
Holding your breath on the other hand would also make you use more oxygen instead so do not do it. Breathe deeply and slowly using your diaphragm and completely fill your lungs then slowly exhale after. Pause for a while before you start to inhale and exhale again.
Doing this lets more gas to get exchanged in your lungs and helps in conserving oxygen. Another way to reduce the use of breathable air supply is to move gently and slowly to limit exertion. Arm movement should be minimized and keep the kicking of your fins within the slipstream for reducing the drag.
Be safe by avoiding to dive under the influence of alcohol or drugs. Carefully listen to the instructor and follow all directions and advice astutely. Stay hydrated while on surface by drinking fluids.
