What is Scotophobia?

Scotophobia, also known as Achluophobia, Nychtophobia, Lygophobia, Nyctiphobia, Nyktosophobia, or Myctophobia, is the irrational and intense fear of darkness. It is a specific phobia and all these terms are used interchangeably. This might be thought of as a “primal” fear of the unknown or what might be “hiding in the dark”, such as monsters, criminals, etc. Phobias of this type are also often related to a fear of losing control.

Scotophobia is believed to be more prevalent in children, though many adults admit to having it.

It derives from the Greek word 'scoto' meaning 'darkness' or 'blindness' and the word 'phobia' comes from the Greek word ‘phóbos’ meaning 'fear.'

Causes of Scotophobia

Scotophobia is a specific (or “isolated”) phobia, centered on non-social key factors. Isolated phobias tend to have some previous trauma (often in childhood and often physically injurious) as a root cause; a fear of bees may stem from an injury in childhood, for instance.

Upbringing can also play a role, such as parental warnings about a direct threat (such as “snakes can bite and kill you”) which is especially notable in cases where a threat is more imminent. (An allergy to bees or peanut butter, for instance, would naturally reinforce a real medical concern.)

It is thought that genetics and hereditary factors may play a role in specific phobias, especially those related to a danger of injury. (A primal “fight or flight” reflex may be more easily triggered in those with a genetic predisposition, for instance.)

By contrast, social phobias (like a fear of body odor or touch) are less well-understood, are driven by social anxiety, and are broadly labeled as “social anxiety disorder”.

In all kinds of phobias, external experiences and / or reports can further reinforce or develop the fear, such as seeing a family member or friend who is affected. In extreme cases, indirect exposures can be as remote as overhearing a reference in conversation, seeing something in the news, on TV, or in the movies.

Scotophobia, like most phobias, stems from a subconscious overprotection mechanism, and as with many phobias can also be rooted in an unresolved emotional conflict.

Scotophobia has been associated with evolutionary causes.
