Chronic Stress and the Body; What Happens When the Nervous System Remains on Alert?

Stress is not necessarily a negative process. In certain situations it helps us focus, respond quickly and cope with the demands of our environment. When the challenge passes, the body’s regulation mechanisms support recovery.

In chronic stress, by contrast, the demands persist or recur frequently, and the opportunity to recover from them is limited.

It is important to be precise: this does not mean that the sympathetic nervous system operates at maximum intensity without a break. Chronic stress may be expressed in complex changes in the activity patterns of the stress systems, which differ from person to person.

One of the central systems involved in the stress response is the hypothalamic-pituitary-adrenal (HPA) axis. This system takes part in regulating the release of hormones, including cortisol, which helps the body cope with changing demands. Cortisol plays essential roles in regulating metabolism, immune system activity and sleep-wake cycles. In states of chronic stress, changes may appear in its secretion patterns and in the way the body responds to it. At the same time, it is not correct to assume that every person experiencing chronic stress has high cortisol levels. The hormonal response is complex and depends on many factors.

The term allostatic load (Allostatic Load) describes the cumulative cost that may arise when the body’s systems are required to adapt again and again to stressful situations.

Allostasis is a process in which the body maintains stability through physiological adjustments to changing circumstances. When the demands are ongoing, the adaptation processes themselves may carry a biological cost.

Research links chronic stress to changes in markers related to cardiovascular health, metabolism and immune activity. At the same time, allostatic load is a complex research concept, not a diagnosis that can be made on the basis of a feeling of fatigue or a single blood test.

One of the familiar phenomena during periods of stress is a feeling of fatigue accompanied by difficulty falling asleep. A person may get into bed exhausted, yet keep thinking about the day that has passed or about what awaits them tomorrow. Heightened cognitive and physiological arousal may make the transition to sleep harder and impair its quality.

Lack of sleep, in turn, may affect concentration, patience and the ability to cope with emotional demands. In this way a cycle may develop in which strain harms sleep, and poor sleep makes it harder to cope with the strain.

During periods of prolonged strain, people may report forgetfulness, difficulty focusing or a sense that they are struggling to think clearly. One possible reason is that attentional resources are largely directed toward coping with worries and competing demands. In addition, stress may affect brain processes involved in working memory, learning and executive functions. At the same time, difficulties with concentration and memory do not necessarily indicate stress. They may also stem from sleep disorders, medical conditions, medications or other factors.

The source of stress is not always the number of tasks alone. Sometimes the meaning a person gives to responsibility affects the way they cope with it. A person who believes they must not disappoint others may keep taking on commitments even when their capacity is limited. Another may find it hard to delegate because they fear that if they do not do everything themselves, things will not be handled properly.

From a psychotherapeutic perspective, it is important to examine the beliefs and patterns that maintain the strain, rather than settling for a general recommendation to rest more. At the same time, it must be acknowledged that stress sometimes stems from real external conditions, such as occupational strain, financial difficulties or caregiving responsibilities, which cannot be solved through a change in thinking alone.

Coping with chronic stress sometimes requires a combination of changing life circumstances and developing ways of regulation and recovery.

Tailored physical activity, sufficient sleep, supportive social connections and reducing avoidable burdens may contribute to health and emotional well-being. Relaxation, mindfulness and breathing practices may also help some people reduce tension.

Within complementary medicine, massage may contribute to a sense of calm and to temporary relief of muscle tension. At the same time, there is insufficient evidence that massage alone corrects physiological changes related to chronic stress.

From a therapeutic perspective, the goal is not only to create moments of calm, but to examine how the price a person pays over time can be reduced.

When ongoing stress is accompanied by significant sleep disturbances, a decline in functioning, anxiety, depression or physical symptoms, it is important to consider a professional evaluation.

Symptoms such as heart palpitations, severe fatigue or persistent pain should not be automatically attributed to stress, and their medical source should be investigated as needed.

Psychotherapy can help identify stressors, work on coping patterns and develop more effective ways of managing the strain.

Chronic stress is not necessarily expressed as a constant feeling of pressure. Sometimes it becomes such a familiar part of the routine that it is hard to notice its effect.

The integrative psychotherapeutic approach makes it possible to address both the physical effects of the strain and the life circumstances and patterns that maintain it.

Meaningful coping with chronic stress is not measured only by the ability to relax at the end of the day, but also by the possibility of creating a way of life in which the body and mind are not required to operate beyond their resources over time.
