Thalassophobia is an intense and often irrational fear of the ocean or large bodies of water. Unlike a general discomfort around water, thalassophobia can cause severe anxiety and avoidance behaviors that interfere with daily life. In this article, we’ll explore what thalassophobia is, its symptoms, causes, and treatment options to help those affected manage their fear.
What Is Thalassophobia?
Thalassophobia is a specific phobia characterized by an overwhelming fear of the sea or deep, open water. This fear often extends to large lakes, rivers, or even swimming pools. People with thalassophobia may feel anxious about what lies beneath the water’s surface, such as sea creatures, shipwrecks, or the vast, unknown depths.
While it’s normal to feel cautious around large bodies of water, thalassophobia goes beyond typical caution and can lead to panic attacks or avoidance behaviors.

1. Traumatic Experiences
- A past negative experience involving water, such as a near-drowning incident or witnessing a water-related accident.
2. Evolutionary Factors
- Some researchers believe that fear of deep water may be an evolutionary survival mechanism, as humans are not naturally equipped to survive in large bodies of water.
3. Media Influence
- Movies, documentaries, or stories about ocean dangers (e.g., sharks, shipwrecks) can amplify fears.
4. Genetics and Environment
- A family history of anxiety disorders or phobias may increase the likelihood of developing thalassophobia.
