In today's fast-paced world, many people don't realize they are in a state of chronic stress. The body continues to "work," but gradually depletes its resources. Regular exercise stress level test allows you to timely detect critical changes in the functioning of the nervous, endocrine and cardiovascular systems. This is not just a diagnosis of the emotional state, but a real prevention of psychosomatic and metabolic disorders.

What is stress and how is it measured?

Stress is the body's physiological response to external or internal stimuli that disrupt homeostasis. The level of stress is complex indicator, which encompasses subjective perception (emotions, behavior), neurohumoral changes (hormones) and physiological response (heart rate, sweating, blood pressure).

It can be assessed in three main ways:

  1. Psychological tests

  2. Biomarkers in blood or saliva

  3. Functional tests of nervous regulation

Testing methods: structure, application, accuracy

MethodType of studyScope of applicationInformativeness / Accuracy
Perception of Stress Scale (PSS)Psychological testInitial evaluation by a psychologist or therapistSubjective, average accuracy
Cortisol in saliva or bloodBiochemical analysisEndocrinology, psychosomaticsHigh, but depends on circadian rhythm
Alpha-amylase in salivaStress biomarkerSports medicine, psychophysiologyHigh during acute stress
Heart rate variability (HRV)Functional testCardiology, psychophysiologyObjective, medium-high
DAS scale (depression–anxiety–stress)Psychological questionnaireClinical psychology, psychiatryHigh for prolonged distress
Skin conductivityPhysiological reactionNeurophysiology, biofeedbackSensitive to short-term changes

Stress hormones: what biochemistry shows

The main stress hormone is cortisol — a product of the adrenal cortex. In short-term stress, it mobilizes strength, but in chronic stress, its excess causes sleep disturbances, decreased immunity, accumulation of visceral fat, and even destruction of muscle tissue.

Other indicators:

  • Adrenalin, noradrenaline — rapid response to danger;

  • DHEA — cortisol antagonist, indicates adaptive reserve;

  • Chromogranin A — a marker of neuroendocrine arousal, especially in patients with hypertension.

HRV measures the difference in intervals between heartbeats. Low variability indicates reduced activity of the parasympathetic nervous system, that is, the body's weak ability to recover. It is this test that is reliable predictor of mortality in cardiology and an indicator of chronic overload.

How to prepare for the test

For the most accurate results:

  • avoid coffee, physical activity and emotional stress for 12 hours;

  • for biochemical tests, donate blood in the morning on an empty stomach;

  • before the psychological test, be in familiar conditions, without stimuli;

  • Do not take adaptogens or hormonal drugs without consulting your doctor.

Self-diagnosis: when a test is necessary

  • if you wake up tired, even after a full night's sleep;

  • if you have sudden mood swings for no reason;

  • if you often have headaches or memory problems;

  • if weight, appetite or blood pressure have become unstable;

  • if performance decreases and habitual activities cause fatigue.

In such cases simple psychological or biochemical test can prevent the development of emotional burnout, neurosis, depression, or somatic complications.

How to interpret the results

Cortisol:
– normal in the morning — 138–690 nmol/l
– too high values may indicate chronic stress or Cushing's syndrome
– too low — adrenal insufficiency or depletion of reserves

HRV:
– low SDNN or RMSSD value is a sign of overload or prolonged sympathetic excitation
– high HRV is a good indicator of recovery and adaptation

PSS > 20 points — requires clinical intervention
DAS > 14 — high probability of distress or depression

A comprehensive interpretation should always take into account the clinical picture and associated factors (age, chronic diseases, lifestyle).
