A new study published in the journal BMC Public Health has sparked debate over the potential negative effects of sleeping separately on older couples. The research, conducted by researchers in Taiwan, surveyed 860 elderly heterosexual couples in Northern Taiwan to examine the relationship between sleep arrangements and psychological well-being. The findings suggest that older couples who sleep in separate rooms may experience a decline in their mental well-being, measured by reduced happiness, life satisfaction, and sense of fulfillment compared to couples who share a bed.
The study highlights a growing tension between modern lifestyle trends advocating for sleep separation and traditional views on relationship health. While trends like “sleep divorce” and the Scandinavian sleep method—popularized in Nordic countries—have encouraged the practice of sleeping apart, this latest research challenges the assumption that such practices universally promote happiness and well-being. The researchers emphasize that sleeping arrangements should be considered within the context of a couple’s relationship, rather than as an isolated lifestyle choice.
Wendy Troxel, a sleep expert at the RAND Corporation, noted that while the study shows an association between sleep separation and reduced psychological well-being, it does not establish causation. She pointed out that couples who sleep separately may already face health challenges such as sleep apnea, chronic illness, or insomnia, which could influence both their decision to sleep apart and their mental health. Additionally, the study did not explore the reasons behind the decision to sleep apart, which is often a key factor in determining how such a choice affects the relationship.
Troxel also emphasized the importance of sleep in maintaining emotional and mental health, particularly for older adults, who are more vulnerable to sleep disruptions and mental health issues like depression, anxiety, and loneliness. She cautioned that while sharing a bed can foster closeness and security, the decision to sleep separately should be based on mutual communication and consider the impact on both partners’ well-being. For some, sleep separation may be a beneficial choice for managing sleep disorders or conflicting sleep habits, but the right approach varies depending on individual circumstances.
Despite the potential benefits of physical closeness, such as the release of oxytocin and the reduction of stress hormones, partners may still face challenges like disrupted sleep due to factors such as snoring or differing body temperatures. Experts caution that poor sleep quality can impair emotional regulation and patience, key components of a healthy relationship. Couples sleeping apart can still maintain intimacy through shared routines, such as winding down together before bed, to support emotional connection and long-term well-being.
