A simple definition
A stressor is anything that triggers a stress reaction in your mind and body.
This reaction is experienced through thoughts, emotions, and physical sensations.
Stressors are often identified as external events such as workload, conflict, or uncertainty. However, these situations only become stressful when they activate an internal response.
Common examples of stressors
Stressors in everyday life often include:
- Work deadlines or pressure
- Relationship conflict
- Financial concerns
- Health worries
- Major changes or uncertainty
- Feeling judged, evaluated, or not good enough
These are external situations that commonly coincide with stress reactions.
The missing layer: internal stressors
The same situation can feel completely different depending on the person experiencing it.
This is because stress is also shaped by internal activation such as:
- Memories
- Beliefs
- Imagined outcomes
These are experienced as mental imagery — internal sensory representations of experience.
The internal layer: Mental imagery
In this article, mental imagery refers to the sensory representations through which we experience memories, beliefs, expectations, and imagined events. These representations may include visual images, sounds, bodily sensations, and other forms of internal sensory experience.
How stress is generated
A stressor is something that triggers a stress reaction.
In everyday understanding, stressors are seen as external events. However, these events only become stressful when they activate internal sensory representations (mental imagery).
These internal representations — experienced as memories, beliefs, expectations, or imagined outcomes — trigger the stress reaction in the form of thoughts, emotions, and physical sensations.
The key point is this:
Stress is not caused by events alone, but by the activation of internal representations associated with those events.
Expanding the definition: eliminating the trigger
When we understand stress in this way, the focus shifts.
Instead of asking:
“How do I manage or remove the stressor?”
We can begin to ask:
“What memory or belief is being activated right now?”
Logosynthesis perspective
Logosynthesis® offers a powerful model to guide this work. You may start with the distressing thoughts, emotions and physical sensations or at times, the mental imagery is vivid and present. Using a simple, guided process, you can identify and shift the stressor so it loses its activating impact. The stress reaction naturally changes or subsides.
This is what is meant by eliminating the trigger: not removing life events, but releasing the memory or beliefs they activate.
A simple reflection
When stress arises, it can help to shift attention from external situations to internal experience:
- What thoughts are active right now?
- What emotions am I experiencing?
- What is happening in my body?
- What am I imagining or remembering?
From this awareness, the triggering internal patterns become visible. When these patterns shift, the stress reaction also shifts. In this sense, internal stressors lose their activating power, and external stressors lose their intensity.
Bringing it together
A stressor can be understood in two complementary ways:
- External view: a situation that triggers stress
- Experiential view: an external situation that activates sensory representations or mental imagery, which generate the stress reaction
Both describe the same phenomenon at different levels of depth.
The experiential view provides greater agency to change how stress is experienced without needing to change external circumstances.
If you want to go further
This perspective opens the possibility of transforming how you respond to life’s challenges, rather than only managing external conditions.
