The term for the fear of darkness is "nyctophobia" or "scotophobia." This anxiety disorder manifests as an intense fear of the dark or nighttime situations, often leading individuals to avoid going out or engaging in activities that may occur in dimly lit environments. Those suffering from nyctophobia may experience panic attacks, elevated heart rates, and feelings of helplessness when confronted with darkness. Treatment often includes therapy approaches, such as cognitive-behavioral therapy (CBT), to help individuals confront their fears gradually. Understanding this phobia is important for providing support and guidance to those who struggle with it, ensuring they can manage their fears effectively.
