Overview
Arachnophobia is a specific phobia brought about by the irrational fear of spiders and other arachnids such as scorpions and ticks. The word Arachnophobia comes from the Greek words arachne and phobia.
Signs and symptoms
People with arachnophobia tend to feel uneasy in any area they believe could harbour spiders or that has visible signs of their presence, such as webs. If arachnophobes see a spider, they may not enter the general vicinity until they have overcome the panic attack that is often associated with their phobia. Some people scream, cry, have emotional outbursts, experience trouble breathing, sweat and experience increased heart rates when they come in contact with an area near spiders or their webs. In some extreme cases, even a picture, a toy, or a realistic drawing of a spider can trigger intense fear.
Reasons
Arachnophobia may be an exaggerated form of an instinctive response that helped early humans to survive or a cultural phenomenon that is most common in predominantly European societies.
