Step 1: Understanding and Managing Dive Anxiety

Diving is an incredible experience, but for many, it can come with a mix of excitement and nervousness. Feeling anxious before or during a dive is completely normal—even experienced divers have moments of doubt. The key is understanding your fears and learning how to manage them, so they don’t hold you back from enjoying the underwater world.

Just as a sudden storm can churn the ocean into a treacherous and chaotic landscape, your thoughts can swiftly transform a pleasant dive into a challenging ordeal.

My First Experience with Diving

Back in 2006, as a college student, I signed up for a study abroad program in The Bahamas. Part of the curriculum required becoming Open Water Scuba Certified. I completed all the confined water skills with minimal issues—though I found mask removal challenging, and learning to control my breathing and relax was more difficult than I had expected.

I had always been a strong swimmer, spending summers in lakes and pools, and even working as a lifeguard throughout high school and college. Water was my second home—or so I thought. But on my first open water dive, anxiety hit me hard. I felt sick to my stomach before we even got in the water. While I didn’t actually get seasick, I was unusually quiet, completely lost in my thoughts.

We geared up and prepared to enter the water.

"Divers on the starboard side ready? Back roll into the water in 3, 2, 1, GO GO GO!"

I hit the water and surfaced, giving the "OK" sign to the boat captain. I took a deep breath and switched to my regulator, ready to descend. But as I looked down into the deep blue, unable to see the bottom, my breathing faltered. My regulator was functioning, but it felt like I couldn't get enough air. I tried to take another breath—nothing. Panic set in. Instinct took over. I bolted to the surface, ripping out my regulator. It was only a five-foot ascent, but it felt like I had just shot up from 100 feet. At the surface, I yanked off my mask, fumbled with my weights, and struggled to inflate my BCD. I was in full panic mode.

I had been so confident that this would be easy. That moment shattered me. I was already thinking about calling home, telling my family that I was giving up, and flying back that night. "I can’t do this. I can’t breathe underwater. I’m done. I quit."

That surface interval was the longest and loneliest of my life. Everyone around me was buzzing with excitement, sharing their first-dive experiences, while I sat in silence, feeling defeated.

Determined to try again, I geared up for dive two. I convinced myself I could push through. "This time will be different," I thought. Safety checks completed, I lined up with the others.

"Divers on the port side, ready? 3, 2, 1, GO! OK, starboard side, your turn! 3, 2, 1, GOOOOOOO!"

One by one, my fellow divers rolled into the water. But I couldn't move. My body refused. I was paralyzed by the fear of not being able to breathe. Instead of joining them, I just sat there, unable to fight the overwhelming anxiety. I had signed up for this adventure, this semester abroad, and I couldn’t even complete the most basic part of the training. It was crushing.

Now, if you know me, you know this isn’t where my story ends. In a later blog, I’ll share how one very important person helped me overcome this fear—changing not only my ability to dive but the entire trajectory of my life and career. Stay tuned!

What Causes Dive Anxiety?

Recognizing where your anxiety comes from is the first step in overcoming it. Dive anxiety can stem from a multitude of sources. The following list is just a few of the ones commonly heard from nervous divers.

• Fear of the unknown – The deep, vast ocean can feel intimidating. The thought of descending into an environment where visibility can be limited may trigger anxiety. Many new divers struggle with the idea of not knowing what’s below them or being unable to see the bottom. Thoughts of marine life and the potential of unpredictable behavior can be a trigger as well (though much of this is made up in our minds due to Hollywood and overactive imaginations). Over time, experience and familiarity help reduce this fear, but it is a common source of anxiety in the beginning.

• Equipment concerns – Worrying about malfunctions or unfamiliar gear. Whether it's a leaking mask, a difficult-to-clear regulator, or concerns about running out of air, equipment-related fears are normal. Many divers feel anxious about whether they’ll remember how to use their gear properly, or if it will work when they need it most. The best way to overcome this is through practice, routine equipment checks, and trusting your training.

• Lack of confidence in skills – Feeling unprepared or inexperienced. Diving requires mastery of various skills, and for beginners, the learning curve can feel overwhelming. If you’re not fully comfortable with skills like mask clearing, buoyancy control, or emergency procedures, self-doubt can creep in. The best way to combat this is by practicing in a controlled environment, such as a pool, until these skills become second nature.

• Claustrophobia or breathing concerns – Managing air supply and depth changes. Some divers feel uneasy about the sensation of breathing through a regulator or the limited space within a wetsuit or drysuit. The idea of descending deeper, where pressure increases and movement feels more restricted, can heighten these feelings. Taking slow, deep breaths and focusing on a relaxed, gradual descent can help ease this discomfort. Choosing dive sites that allow maximum visibility allows you to see in all directions easily and not feel "Trapped" in a situation where you cannot get to the surface or see where you are going.

• Negative past experiences – A previous stressful dive may trigger anxiety. If you’ve had a bad experience—such as a rapid ascent, getting tangled in gear, or struggling with buoyancy control—it can leave a lasting impression. Your brain remembers stress-inducing situations and tries to protect you from them in the future. Addressing past incidents, working through them with an instructor or mentor, and gradually building confidence and skills can help minimize this anxiety.

Techniques to Manage and Overcome Dive Anxiety

1. Deep Breathing Techniques

Controlled breathing is essential for staying calm underwater. Try this before your dive:

• Inhale deeply through your nose for four seconds.

• Hold for four seconds.

• Exhale slowly through your mouth for six seconds.

• This method helps slow your heart rate and keep panic at bay.

  • AND AS A BONUS, Learning slow breathing patterns play a huge role in learning to conserve air while diving!

2. Visualization and Mental Preparation

Ancient Chinese philosopher Lao Tzu once said,

"Watch your thoughts, they become your words; watch your words, they become your actions; watch your actions, they become your habits; watch your habits, they become your character; watch your character, it becomes your destiny.

Before a dive, take a few moments to visualize yourself diving confidently. Picture a smooth descent, relaxed movements, and controlled breathing. This technique helps train your brain for a positive dive experience.

3. Use Positive Affirmations

Your mindset plays a huge role in confidence. Replace negative thoughts like “I can’t do this” with “I am in control and prepared”. Training your brain with positive reinforcement helps shift your perspective.

4. Buddy Communication

Talk to your dive buddy or instructor about your concerns. A supportive team can make all the difference, and having a trusted partner underwater adds reassurance.

6. Trust Your Training

Your training is designed to prepare you for safe and enjoyable dives. Revisit basic skills in a pool or shallow water to remind yourself of what you know and boost confidence.

7. Progressive Exposure

If anxiety is strong, take gradual steps to build comfort:

• Start with shallow dives or confined water practice.

• Focus on one skill at a time (buoyancy control, mask clearing, etc.).

• Progress at your own pace—confidence comes with familiarity.

Your Challenge This Week

• Practice deep breathing every day for a few minutes, be mindful of your breathing patterns, and work on visualizing confidence during your future dives. Our goal will be to work up to at least 5 minutes a day leading up to our next dive vacation.

• Talk to a fellow diver about a fear you’ve had and discuss how to manage it. This allows you to realize all divers experience some version of stress or anxiety and reminds us that these feelings are not unique to only us. If you keep a Dive Log(And you should!) I would encourage you to put a journal entry in your log about the conversation you had with your chosen fellow diver. If you cannot find a fellow diver, reach out to me! I would love to discuss this with you.

Overcoming dive anxiety doesn’t happen overnight, but by applying these techniques, you’ll gradually build confidence and control. You’ve got this! 🌊💪
