Commonly asked questions
Triggers for thalassophobia include exposure to the deep sea or other deep bodies of water, such as lakes or oceans. Media portrayals of sea monsters, traumatic experiences involving water, or hearing stories about accidents at sea can also induce or worsen the fear.
Thalassophobia is often rooted in an intense fear of drowning, being attacked by marine life, or losing control in vast waters. Past traumatic events, such as near-drowning incidents or overwhelming feelings of helplessness in water-related situations, may contribute to the development of this phobia.
