Abstract: Teaching is widely documented as one of the most psychologically and physiologically demanding knowledge-intensive occupations, with chronic exposure to combined intellectual, emotional, and regulatory workloads placing teachers at elevated risk for autonomic dysregulation, cardiovascular strain, cognitive decline, and occupational burnout. A question that occupational health research has not adequately resolved is whether the functional consequences of career-long teaching are driven primarily by biological ageing or by the accumulation of occupationally specific stressor exposure, two processes that are conceptually distinct yet rarely examined separately. We assessed psychophysiological, emotional, and cognitive indicators in 103 female secondary school teachers in Karaganda, Kazakhstan, stratified by age and length of service. The assessment battery included heart rate variability recording, systolic and diastolic blood pressure measurement, the Ruffier physical performance index, the Well-being, Activity, and Mood questionnaire, the Spielberger-Khanin State Anxiety Inventory, the Landolt ring correction test, a digital selective attention test, and three sensorimotor reaction time measures. To allow direct comparison of the explanatory power and predictor composition of the two variables, separate multiple linear regression models were constructed with chronological age and length of professional service as dependent variables, with the full psychophysiological battery serving as independent variables in both. Chronological age and length of service were strongly intercorrelated (r = 0.915; p
