Nyctophobia is an age-inappropriate fear of darkness that can prompt someone to limit their activities, avoid certain situations, and experience anxiety in anticipation of there being no light.While being afraid of the dark may be a part of normal development in young children, that is not the case for older children and adults.

It is when the concern crosses over from being an inborn protective mechanism to disrupting everyday life that it is designated a phobia.

What Causes Nyctophobia?

Nyctophobia, also referred to as scotophobia, achluophobia, and lygophobia, may be evolutionary in nature, as many predators hunt at night. The fear may not be related to darkness itself but unknown dangers hidden in the darkness (which is why horror and suspense movies often use darkness as a way to scare viewers).

Lack of security and confidence can play into this as well, especially if you tend to be afraid of the dark more often whilealone.

Somepsychoanalyticwriters believe that fear of the dark may be related to separation anxiety from a primaryattachmentfigure, a phenomenon that is detailed further in a 2014 analysis on attachment and fear arousal published in the journalPsychoanalytic Dialogues.

Genetics, upbringing, experiences, and brain structure differences can also play a role in the onset of specific phobias.

How Is Nyctophobia Diagnosed?

There is no specific test to look for nyctophobia. Instead, a doctor or therapist will ask questions about your medical history and symptoms.

It is also essential to recognize that nyctophobia is not a distinct condition in the “Diagnostic and Statistical Manual of Mental Disorders” (DSM-5-TR). It is instead considered a type ofspecific phobia.
