The common name for the fear of spiders is arachnophobia. This specific phobia affects a significant number of people and can range from mild discomfort to severe anxiety at the thought or sight of a spider. Symptoms may include panic attacks, sweating, rapid heartbeat, and avoidance of situations where spiders might be present. Arachnophobia is thought to have evolutionary roots, as some spiders can be venomous. Treatment options include cognitive-behavioral therapy, exposure therapy, and mindfulness techniques to help individuals manage their fears. It is one of the most common phobias in the world today.
