Thalassophobia is an intense and irrational fear of the sea or deep water.
Individuals with thalassophobia may experience anxiety, panic attacks, or extreme discomfort when they are in or near large bodies of water, especially when they cannot see the bottom or when the water is murky or deep.
This fear can stem from various factors, including the fear of the unknown, the vastness of the ocean, the potential for drowning, or fear of the creatures that inhabit the depths.
Thalassophobia can vary in severity from mild unease to debilitating terror and may interfere with a person's ability to enjoy activities involving water or coastal areas.
Treatment options for thalassophobia may include therapy, cognitive-behavioral techniques, exposure therapy, and relaxation exercises.
