Blood phobia
Blood phobia (also, AE: Hemophobia, BE: Haemophobia, from Greek αἷμα - haima, "blood"[1] and φόβος - phobos, "fear"[2]) is the extreme and irrational fear of blood. Acute cases of this fear can cause physical reactions that are uncommon in most other fears, specifically vasovagal syncope (fainting).[3] Similar reactions can also occur with trypanophobia and traumatophobia. For this reason, these phobias are categorized as "blood-injection-injury phobia" by the DSM-IV.[4] Some early texts refer to this category as "blood-injury-illness phobia."[5]
Etiology
Blood phobia is often caused by direct or vicarious trauma in childhood or adolescence.[5] Though some have suggested a possible genetic link, a study of twins suggests that social learning and traumatic events, rather than genetics, is the primary problem.[6]
Treatment
The standard approach to treatment is the same as with other phobias - cognitive-behavioral therapy, desensitization, and possibly medications to help with the anxiety and discomfort. In recent years, the technique known as applied tension, applying tension to the muscles in an effort to increase blood pressure, has increasingly gained favor as an often effective treatment for blood phobia associated with drops in blood pressure and fainting.[7][8][9] [10]
