Triggers can be very subtle. Your nervous system can detect them even when you are not consciously aware of what it noticed.
Triggers can also come from internal experiences, not just things in the environment. For example, someone might notice their heart beating quickly, and that awareness can trigger a panic response.
Another reason triggers can be difficult to identify is that they don’t always directly relate to the traumatic event itself. If you are familiar with Pavlov’s dogs, he discovered that the dogs began to associate the sound of a bell with being fed. Even though the bell itself had nothing to do with the food, hearing it caused the dogs to start salivating.
Trauma triggers can work in a similar way. The nervous system records sensory details that were present during a threatening experience. Later, those same details may signal danger to the body even when you are safe. For example, if a traumatic event happened on an unusually windy day, you might later feel tense or on edge on other very windy days without knowing why.
Because these associations are often outside conscious awareness and may not seem logically connected to the trauma, triggers can be difficult to identify.
