Last but not least, our study suffers from limitations. First, the marital quality, work status, and menopausal status were not assessed, all of which have been reported to affect sleep (48–50). Second, the present work compares married individuals to never married individuals which means that the actual sleeping arrangement (bed-sharing vs. individual sleep) remains unknown. This could be seen as impairing comparability with the aforementioned studies on co-sleeping that directly manipulate the sleeping arrangement (13, 14, 33). Yet, it is of note that there is a high correlation between the marital statuses and sleeping arrangement: In the US ?87% of the married individuals share a bed with their partner (18) (this number might be lower in elderly couples) and <5% of the elderly population (aged 50 and above, which is comparable to the present sample) are cohabiting (and co-sleeping) while not being married (17). Therefore, it seems rather unlikely that a significant number of neither never married but still bed-sharing individuals nor married but separately sleeping individuals confounds the results and interpretation of the present study.
Nonetheless, upcoming knowledge also needs to are a group of lovers which can be habitually myself sleep to raised distinguish between your results of being inside the a romance (personal means) to bed-setting-particular outcomes. A 3rd extremely important restrict of the establish data is the get across-sectional design which precludes defining impression advice. While the early in the day interventional knowledge demonstrably indicate an effect of the brand new sleep plan to the REM sleep (thirteen, 14, 33) in the current studies both rules is actually-theoretically-you can easily, i.e., REM sleep you’ll increase the likelihood of getting married otherwise vice versa. Actually, this new hypothesized viewpoints cycle from REM bed and you will sociality would expect one both information carry out can be found.
The point that this might be revealed from inside the an inside-victims framework in comparison with https://datingranking.net/pl/smore-recenzja/ (predominantly) constantly in person sleeping never partnered anybody complements early in the day education and you will represents an important not sufficient status into the examining an optimistic feedback circle from REM bed and you may sociality along with REM-bed venture given that apparatus by which relationships benefit psychological state-both of that needs to be treated in the future degree.
