[Various subjective and objective indicators of intellectual and emotional stress in air traffic controllers during different work shifts].

The purpose of the study was to examine air-traffic controllers attending the automated air-traffic management system called Start. The data revealed that during the night shift air-traffic controllers experienced significant changes in body functioning in comparison with morning and day shifts (deterioration of self-appraisal indices and elevation of catecholamin excretion). The correlation analysis demonstrated that activation of sympathoardrenal chains (primarily of the mediator chain) had a negative influence on the indices of health state, activity and attitude of mind of air-traffic controllers.
