W-O-140 SLEEP CHARACTERISTICS OF CHINESE RURAL POPULATION BY PSQI

Abstract

Introduction and Objectives: Despite a long history of interest in emotion regulation as well as in the mechanisms that regulate sleep, the relationship between emotion regulation and sleep is not well described. Materials and Methods: To get insight in this relationship, we examined the effects of pre-sleep painful emotion (i.e., a failure-experience), moderating effects of induced emotion regulation in the recovery from the experience and the effects in shaping sleep physiology assessed by polysomnography (EEG). Results: As hypothesized, results indicate that participants who received experiential emotion regulation showed less fragmentation of sleep by a longer Total Sleep Time, higher Sleep Efficiency with more % REM sleep and Slow Wave Sleep than participants who received analytical emotion regulation. For the group of participants who received experiential emotion regulation, due to its regulatory effect, sleep parameters did not differ between the baseline and the failure night. By contrast, analytical emotion regulation was associated with more Awakenings, more % Time Awake, more Waso (Awake after Sleep Onset), and a longer Latency to Slow Wave-Sleep in comparison with experiential emotion regulation. Conclusion: In the recovery of a painful experience, a beneficial effect of experiential emotion regulation has been observed on sleep physiology, compared to cognitive analytical emotion regulation.
