title: [Sleep stages after psychoemotional exposure: individuality-dependent changes].
abstract: Sleep stages were studied in healthy subjects with the aid of a battery of tests involving questionnaires, psycho-tests, motor tests, polysomnography, and cardiomonitoring. An induced psychoemotional tension was shown to change the 1st sleep stage, to decrease percentage of the 2nd stage of the slow-wave sleep, to redistribute the delta-sleep, and to suppress the REM sleep mechanism. The cerebro-visceral function of increasing the heart rate and its variability in night sleep was also affected. Patterns of the sleep structure changes depended on personality characteristics of the subjects. Thereupon, individual programs should be used in studies of psychoemotional stress effects upon the sleep pattern.
