Thalassophobia is a persistent and intense fear of deep bodies of water such as the ocean or sea. What makes this phobia different than aquaphobia — the fear of water in general — is the fact that it centers on vastness, darkness, and depth. People who have this condition are not terrified of getting wet, but rather the might and mystique behind the waves.
While thalassophobia is not recognized as a distinct disorder by the DSM-5, the diagnostic manual of mental disorders used by psychiatrists and other mental health professionals, it's still relatively common. And the subreddit of the same name is a vivid example of that. Created in June 2013, it unites 969,000 thalassophobes, sharing triggers and discussing symptoms.
So, in an attempt to shed some light on this community, we at Bored Panda decided to put together a list of their most popular posts.

Is To Me Or Are Black Tiled Pools Terrifying
Online groups that get this big often suffer from huge streams of content that flood them with questionable pictures and videos, diminishing the overall experience of browsing them, but this subreddit manages to stay clean.
Part of it can be attributed to the clear rules that promote being nice and courteous, and allow no jokes, memes, or cartoons, no reposts, and no gore.
Of course, having an active moderator team that make sure members adhere to these rules helps tremendously as well.

Specific phobias tend to fall into these five categories:
Animal type;
Blood-injection type;
Natural-environment type;
Situational type;
Other.
Thalassophobia is usually considered to belong to the natural-environment type. These fears are experienced more frequently, with some studies also suggesting that water-related phobias are more common among women.

The causes of specific phobias, including thalassophobia, are not entirely understood, and often differ from case to case. But according to a common explanation, it's usually a combination of genetic and environmental factors.
Research shows that certain genes are associated with certain specific phobias, but as of yet no studies have looked at the genetics behind thalassophobia in particular. However, following the Darwinian theory of evolution, there should still be at least some.

Think of it like this: our ancestors also came across deep bodies of water, and those who were cautious of the dangers they possessed may have avoided them, living longer to pass down their genes. This theory is supported by research that indicates that specific phobias are moderately heritable.
Although the exact percentage can vary, it has been found, for example, that for animal phobias, heritability is around 45%.

Thalassophobia could also be caused by traumatic events, such as a childhood near-drowning experience, witnessing a shark attack, never learning to swim, or even being told scary stories of the ocean.
By associating a specific situation, such as being in deep water, with a panic response, over time a phobia of that situation can develop.

Phobias are chronic conditions that can worsen over the course of life and limit one's relationships and activities. The good thing is that they are also highly treatable, although the process isn't always pleasant.
But only about 10-25% of people with a specific phobia ultimately seek help. This is likely due to avoidance behaviors, since treating a specific phobia does often involve confronting the feared stimuli.

There’s Something Particularly Terrifying About The Idea Of Water You Can’t Even Float In
Exposure therapy is a popular and effective choice for treating specific phobias, including fear of the sea. During it, a person faces their feared stimuli in increasing levels of intensity.
For someone with thalassophobia, this might start with looking at photos of the sea on this subreddit, escalate to watching videos of the ocean or deep water, then visiting a big pool and taking a trip to the ocean. Through controlled exposure, the person learns that the feared stimulus itself is not dangerous, and they can begin to associate it with more positive outcomes.
