People with a blood phobia have a stronger family component than any other type of phobia.


The blood phobia is often caused by a traumatic experience in childhood or adolescence.

Some people with hematophobia also have phobias to doctors or dentists, as they can associate the field of medicine with the blood, particularly by television and movies.

In addition, it can be associated with hypochondria (believing that you are suffering from a disease) and nosophobia (exaggerated fear of contracting diseases).


The approach to treatment is similar to that of other phobias:

Cognitive-behavioral therapy: Be aware of thought patterns that create fear of blood. Negative thoughts are replaced by positive ones. Other aspects that can be included are journal writing and relaxation techniques. Although this therapy is less harsh than desensitization, it is less effective.

Systematic desensitization: learn to cope with the negative emotions associated with the sight of the blood.

Exposure: it is about exposing the person to blood so that he learns to control his fear.

Possibility of medication to help with anxiety and discomfort.

Exercises of muscular tension.

To prevent hematophobia from becoming a major problem, treat it when it is detected.

It is advisable that the treatment be established and guided by a specialist.

Also, surgeries and visits to the dentist can be avoided. On the other hand, parents with hematophobia may find it difficult to heal wounds of children or their children.
