Polysomnographic recordings were obtained in 16 healthy male subjects in order to evaluate temporal interrelationships between concentrations of plasma cortisol and sleep at night. The pattern of nocturnal cortisol secretion appeared to be synchronized with the periodicity of sleep: rapid eye movement (REM) sleep was found to be primarily present when cortisol concentrations were decreasing, indicating a diminished or absent secretory activity of the adrenals at that time; wakefulness and Stage 1 sleep, by contrast, were associated with increasing plasma cortisol concentrations. Furthermore, the enhanced adrenal secretory activity usually preceded the occurrence of light sleep or wakefulness, which is in accord with a wakening effect of plasma cortisol. Just prior to the onset of the first pronounced rise in plasma cortisol during sleep, episodes of slow wave sleep (SWS) became more frequent. This suggests that the offset of episodes of SWS may act as a trigger for the first pronounced nocturnal rise in plasma cortisol.
