Arachnophobia is an intense fear of spiders and other arachnids, such as scorpions. People with this phobia often experience anxiety, panic attacks, or distress when they see a spider or even think about one. This fear can be so overwhelming that it interferes with daily life and activities. The causes of arachnophobia can vary, including negative experiences with spiders, learned behaviors from family, or even evolutionary factors. Treatment options include therapy, such as cognitive-behavioral therapy (CBT), which helps individuals confront and manage their fear in a controlled environment.
