Document Summary
Judy"s reaction reached such an extreme that even hearing someone say cut it out! evoked queasiness. Judy experienced a vasovagal syncope, which is a common cause of fainting: when she saw the film, she became mildly distressed, and her heart rate and blood pressure increased accordingly. Then her body took over, immediately compensating by decreasing her vascular resistance, lowering her heart rate and, eventually, lowering her blood pressure. The tendency to overcompensate seems to be inherited, a trait that may account for the high rate of blood injection injury phobia in families. To cause blood injection injury phobia, a complex interaction must occur between behavioral and biological factors. Emotional influences: emotions can affect physiological responses such as blood pressure, heart rate, and respiration, particularly if we know rationally there is nothing to fear, Fortunately, researchers have discovered a way to correct this disorder: change the way the environment interacts with and affects the genetic expression of this disorder.
