Difficulty: Moderately Challenging
Step1
Find clear water to swim in. Start out in shallows or closed waterways where you can see what's around you, and feel confident that nothing is lurking nearby. A good set of goggles for underwater vision is also a good idea.
Step2
Get assurance from others. Let people without a shark phobia "talk you down" a little. They can reasonably explain to you what your real chances of shark attacks are, regardless of how many times you've just seen somebody get torn apart on-screen.
Step3
Push your boundaries gradually, by going to larger pools or bodies of water, or spending time wading and reflecting on your fears and insecurities. This time can be therapeutic in many ways, letting you think about your shark phobia and whatever else comes to mind.
Step4
Don't force yourself. Try to avoid being persuaded by a "tough-love" philosophy or the idea that fear is to be overcome by sudden immersion. Although in rare cases, you can emerge dripping with adrenaline, this tactic will probably backfire.
Step5
Be reasonable. One of the best ways not to be afraid of sharks is to take all reasonable precautions listed by safety personnel or in guide books. Know your waterways and where to avoid attracting the deep-sea predators. Armed with information, you can float easy, knowing you are not in a "shark zone."
