Over time, this response will gradually reduce, but it may take weeks, or even months and there are some things that can get in the way of this natural ‘resetting’ of your fear response.Īvoidance – Sometimes people avoid any reminder of the traumatic situation. This means if you experience certain sensations, such as feeling like you can’t breathe, or have an image go through your mind (or a nightmare) of the ICU, your ‘Fight or Flight’ response may be triggered automatically. Your brain may well have learned an association between certain physical sensations, images, sounds, smells and danger. If you were in hospital the response works in the same way.

These can seem quite strange or frightening, but they all serve a function and provide what could be a life-saving edge if we are faced by physical danger, such as a wild animal. If we really had no fear, we would probably be involved in some kind of accident very quickly.
