Thalassophobia and a fear of swimming are not necessarily the same. Thalassophobia specifically refers to a fear of the ocean or large bodies of water, while a fear of swimming, known as aquaphobia, is a broader fear of water in general. Aquaphobia can encompass fear of pools, lakes, or even small bodies of water. While Thalassophobia can include a fear of swimming in the ocean, it can extend beyond swimming and encompass fears related to the vastness, depth, creatures, or unknown aspects of the ocean. Understanding the specific fear can help in developing targeted treatment approaches for individuals with Thalassophobia or aquaphobia.
