The common term for the fear of spiders is arachnophobia. This specific phobia is characterized by intense fear or anxiety when encountering spiders, even when they pose no real threat. People with arachnophobia may experience panic attacks, sweating, and a racing heart when they see a spider or even think about one. This fear can stem from evolutionary factors, as some spiders are venomous, or from cultural influences. Treatment options for arachnophobia include psychotherapy, such as cognitive-behavioral therapy, and exposure therapy, which helps individuals confront their fears in a controlled environment.
