Causes and Types of Stress

Core Concepts

Types of stressors

• Physical stressors directly threaten the body: illness, injury, surgery, pain, infection, fever, sleep deprivation, heat or cold extremes.
• Psychological stressors come from the mind: fear, worry, uncertainty about a diagnosis, loss of independence, a frightening prognosis.
• Social stressors involve relationships and roles: conflict, isolation, financial strain, caregiving burden, loss of a loved one.
• Environmental stressors come from the surroundings: noise, bright lights, crowding, an unfamiliar unit.
• Developmental and situational stressors arise from life transitions — a move, a new diagnosis, retirement, pregnancy, hospitalization itself — maturational (life stage) or situational (unexpected event).

Most patients face combinations — a postoperative patient deals with pain (physical), fear of the pathology report (psychological), worry about bills (social), and a noisy unit at night (environmental).

Acute versus chronic stress

Acute stress is the response to a short-lived stressor: time-limited, intense, and — within reason — adaptive. The body mobilizes energy, the person rises to the occasion, and when the stressor ends, the response subsides. Chronic stress is the response to a stressor persisting for weeks, months, or years — ongoing pain, a long illness, caregiving, poverty, chronic conflict. The same hormones that protect during an acute stressor become corrosive when they never switch off: sleep suffers, blood pressure and glucose stay elevated, immune function is altered. This is how chronic stress contributes to disease — which is why assessing the duration of stress is clinically important.

Eustress versus distress

Not all stress is bad. Eustress is positive stress — the kind that comes with challenge and excitement, like a wedding or a promotion. It still activates the stress response, but the person experiences it as energizing. Distress is stress experienced as overwhelming or harmful — the feeling of being stretched beyond one's capacity. The same event can be eustress for one person and distress for another; the difference is largely in appraisal and resources.

Appraisal: why the same event stresses one person and not another

The transactional model of stress (associated with psychologist Richard Lazarus) proposes that stress depends on how a person appraises an event:

• Primary appraisal: "Is this a threat, a challenge, or irrelevant to me?"
• Secondary appraisal: "Do I have the resources to cope?" — health, skills, money, time, information, support.

If an event is appraised as threatening and coping resources seem inadequate, the stress response is strong; appraised as a manageable challenge, it is milder or even positive. This is why information, preparation, and support are powerful nursing interventions — they change the secondary appraisal.

Coping: problem-focused and emotion-focused

Coping is the effort to manage stress, in two broad styles:

• Problem-focused coping changes the situation itself — gathering information, making a plan, asking for help. Works best when the stressor is changeable.
• Emotion-focused coping changes how the person feels — seeking comfort, talking it through, relaxing, reappraising the event's meaning. Essential when the stressor cannot be changed (a terminal diagnosis, a loss).

Healthy coping usually mixes both; unhelpful coping — avoidance, substance use, withdrawal — may reduce distress in the moment but increases it over time.

Vulnerability, protective factors, and nursing assessment

The same stressor hits people differently depending on vulnerability factors (age, health problems, limited support, previous trauma) and protective factors (strong relationships, good health, stable resources). The nursing assessment of stress therefore goes beyond "Are you stressed?": what are the stressors, how long have they been present, how does the patient perceive them, what resources exist, how has the patient coped before, and how does stress show up physically? The plan of care then targets the identified stressors.
