6. Nyctophobia (Fear of the Dark)
Nyctophobia, or fear of the dark, is common among children but can persist into adulthood. It often stems from the fear of the unknown or imagined threats in the dark. Gradual exposure to darkness in a safe environment, along with cognitive therapy, can help reduce this fear. Relaxation techniques, such as deep breathing or progressive muscle relaxation, are also effective in calming anxiety before bed.
