The common term for a fear of spiders is "arachnophobia." This specific phobia affects many individuals, often causing anxiety or panic at the sight of spiders or even at the thought of them. Symptoms can range from mild uneasiness to extreme fear, leading to avoidance behaviors. The origin of arachnophobia may stem from evolutionary responses to potential dangers posed by some spider species, although the degree of fear varies among individuals. Treatment options such as cognitive-behavioral therapy (CBT) and exposure therapy can help individuals manage and overcome their fears, allowing for a better quality of life.
