According to a study by the University of Zurich, taking cortisone helps to overcome different types of phobias. Specifically, they have carried out the experiment with people who have too many fears to speak and spiders, and in both cases have seen that cortisone benefits them: before the cause of fear, the heartbeat does not accelerate so much, do not feel so much fear...
In addition, the influence of cortisone lasts quite a lot, and it is believed that it can serve to overcome phobia definitively. In the case of those who had phobia of spiders, they gave cortisone for two weeks and showed that they did not feel phobias after treatment.
Apparently, cortisone influences memory and reduces the fear they have felt in previous experiences, which makes it easier for them to face what generates fear. However, it is still early to be used in anti-phobias therapies, since they have performed the experiment with few people and have not measured well doses, side effects and interactions with other medications.
