“…In other studies, in undergraduate samples, acting with awareness and non-judgement were associated with higher sleep quality on the PSQI, while observing had negative effects. 18 , 74 Recent work in an undergraduate student sample found that the associations between observing and sleep health were moderated by non-reactivity : observing was associated with worse sleep at lower levels of non-reactivity , but better sleep health at higher levels of non-reactivity . 28 …”

Objective Poor sleep among young adults is prevalent, yet the mediating variables are largely understudied, and there is limited relevant work utilizing objective sleep measures. The present study investigated the mediating effects of perceived stress and rumination in the relationship between trait mindfulness and subjective and objective sleep quality in young adults. Methods A total of 170 healthy adults (aged 18–37, M = 20.8, SD = 2.9) self-reported on trait mindfulness, perceived stress, and rumination. The primary ( N = 140) and secondary ( N = 30) samples both completed the Pittsburgh Sleep Quality Index (PSQI) to assess subjective sleep quality. The secondary sample ( N = 30) additionally provided sleep diaries, as well as wrist-worn actigraphy data for assessing objective sleep quality. A mediation analysis was conducted to assess the effect of trait mindfulness on sleep quality with perceived stress and rumination as mediators. Results Trait mindfulness was positively associated with better subjective sleep quality; this was fully mediated by perceived stress, b = −0.08, 95% CI [−.12, −0.06]. Rumination was negatively associated with subjective sleep quality but did not mediate the relationship between trait mindfulness and sleep quality, b = −0.01, 95% CI [−.03, 0.02]. Only trait mindfulness was correlated with diary-based sleep ratings, and none of the measures were associated with actigraphy-based sleep quality. Conclusion This study indicates that perceived stress is an important mediator in the relationship between trait mindfulness and subjective sleep quality among young adults, rather than rumination. These findings have implications for mindfulness-based therapeutic approaches to address the high prevalence of sleep disorders among young adults, adding mechanistic detail to the literature.

“…The authors further investigated objective sleep parameters—measured via actigraphy—and found no significant association with trait mindfulness. However, recently, it was shown that a sleep health score, as quantified by six domains including two subjective measures and four actigraphy-based measures of sleep, namely sleep regularity, duration, timing, and efficiency, was positively associated with trait mindfulness [ 19 ]. While actigraphy offers a convenient method for tracking sleep patterns, the more reliable gold standard to measure objective sleep is polysomnography, which depends on electroencephalographic (EEG) measures of brain waves.…”

Study Objectives Mindfulness describes the ability to focus on the presence, including one’s thoughts and feelings. Trait mindfulness – a person’s inherent tendency to be mindful – has been connected to increased subjective sleep quality, but evidence from objective EEG-based sleep measures is lacking. Here, we investigate whether objective EEG-based sleep parameters explain interindividual differences in trait mindfulness. Methods Whole-night polysomnographic data were gathered from 52 healthy adults (27 females; agemean = 21.5 (SE = 0.28)) in their home using a portable high-density EEG-device. Trait mindfulness was assessed using the Five Facet Mindfulness Questionnaire short form (FFMQ-SF). Results Trait mindfulness was positively correlated at trend-level with the percentage of REM, but not N1, N2 or SWS. Additionally, those exhibiting less REM beta/gamma power and NREM beta power displayed higher trait mindfulness and vice versa. Lastly, we replicated findings connecting higher trait mindfulness to better subjective sleep quality. Conclusions REM sleep is pivotal for emotional processing. Decreased REM high-frequency activity was suggested to reflect adrenergic reduction that defuses affective experiences. Increased NREM high-frequency activity is a marker for cognitive hyperarousal in insomnia. We speculate that differences in trait mindfulness might be explained by differences in REM- and NREM-sleep functions that promote ideal emotional regulation and prevent hyperarousal.
