Fear of the dark, also known as nyctophobia or scotophobia, is a common anxiety that many people experience. It often stems from the unknown, as darkness can obscure familiar surroundings and create feelings of vulnerability. This fear can manifest in both children and adults, leading to anxiety, restlessness, or avoidance of dark places. In children, fear of the dark is a normal developmental phase, often linked to their imagination and inability to distinguish between reality and fantasy. For some, this fear may persist into adulthood, potentially affecting their daily lives. Various treatments, including cognitive-behavioral therapy and gradual exposure, can help individuals manage and overcome this fear.
