The present study aimed to explore dynamic and interactive aspects of cosleep in heterosexual couples. The sample consisted of eight young healthy adults who belonged to four heterosexual couples with a good relationship quality and a history of cosleeping. All individuals underwent simultaneous polysomnography in a sleep laboratory for four nights in which they slept individually and with their partner. Also, a sleep protocol of subjective sleep measures was completed. Statistical analyses included cross recurrence quantification analysis to assess synchronization during sleep. Cosleeping was associated with better subjective sleep quality, increased total sleep time, sleep efficiency, total slow wave sleep, and REM sleep. Sleep stages were more synchronized during cosleep independent of awakenings. Cardiorespiratory measures remained unchanged. The results indicate that young healthy couples in good relationships benefit from cosleeping on a subjective and objective level. Combining simultaneous polysomnography and cross recurrence quantification analysis is a promising method to study dynamic and interactive aspects of cosleep possibly leading to deeper understanding of the role of sleep for sociality, the nature of REM sleep, and the partner as a social zeitgeber. Moreover, clinical implications may arise from these findings.
本研究旨在探索异性恋伴侣同床共眠的动态和交互方面。样本包括八名年轻健康的成年人，他们分属于四对异性恋伴侣，关系质量良好且有同床共眠的经历。所有个体在睡眠实验室进行了四晚的同步多导睡眠监测，期间他们分别独自睡眠以及与伴侣同床共眠。此外，还完成了一份主观睡眠测量的睡眠方案。统计分析包括交叉重现量化分析，以评估睡眠期间的同步性。同床共眠与更好的主观睡眠质量、更长的总睡眠时间、睡眠效率、总慢波睡眠和快速眼动睡眠相关。在同床共眠期间，无论是否醒来，睡眠阶段的同步性都更高。心肺测量结果保持不变。结果表明，关系良好的年轻健康伴侣在主观和客观层面都能从同床共眠中受益。结合同步多导睡眠监测和交叉重现量化分析是一种很有前景的方法，可用于研究同床共眠的动态和交互方面，这可能有助于更深入地理解睡眠对社交的作用、快速眼动睡眠的本质以及伴侣作为社会时间调节器的作用。此外，这些发现可能具有临床意义。
