Experiment reveals sleep duration impacts autonomic nervous system and sympathetic activity in healthy women during exercise.

The study aims to investigate how sleep duration impacts brain and autonomic responses to exercise.
Random assignment of 40 healthy female students to sleep restriction or normal sleep groups.
Measurement of EEG-derived indices, heart rate, and PPG-derived autonomic nervous system indices pre- and post-exercise.
Analysis of group × time interaction effects using two-way mixed-design ANOVA.
TBR and SEF-90 indices differed significantly post-exercise between sleep groups.
HRV index decreased and sympathetic activity increased significantly in the sleep restriction group.
Heart rate and rating of perceived exertion were significantly higher in the sleep restriction group.

Jung et al. (2026) studied this question.
