Stress / Stressor / Stressful Event

Stress describes the experience a person has while being impacted by one or more stressors, often characterized by psychological distress and physiological changes (e.g., increased heart rate, shallow breathing, muscle tension).
Stress is a common experience and some stress can be a good thing if the stress leads to growth and adaptation; however, stress can result in psychological trauma.
A stressor is a physical, radiological, biological, socioeconomic, or psychological force that acts upon a person during events such as a motor vehicle accident, loss of an important relationship, loss of employment, confronting an attacker, dealing with financial loss, or adverse childhood experiences.
A psychologically stressful event is an episode in time during which a stressor operates on a person and causes an emotional experience accompanied by predictable biochemical, physiological, and behavioural changes.
Confusingly, the word stress is often used synonymously, sometimes mistakenly, when people are referring to traumatic stress, psychological trauma, a mental health condition, or a mental disorder associated with experiencing a stressful event.
Stress, stressor, and stressful event are often used interchangeably to refer to a potentially psychologically traumatic event or an adverse childhood experience.
