Interactions between co-sleeping, sleep quality, and relationship health: The benefits and challenges of shared sleep environments

Sleep quality and marital satisfaction are closely linked, with co-sleeping dynamics playing a significant role in this relationship. This narrative review explores the complex interactions between co-sleeping, sleep disorders, and relationship health, highlighting both the benefits and challenges of shared sleep environments. While co-sleeping can enhance emotional intimacy and improve sleep synchronization, it can also exacerbate sleep disturbances, particularly in the presence of sleep disorders, such as insomnia or obstructive sleep apnea. The concept of "sleep divorce," in which partners sleep separately to optimize sleep quality, is discussed as a potential strategy to balance these challenges. Future research should focus on personalized interventions that consider the unique needs of couples, the impact of sleep disorders on co-sleeping, and the long-term effects of different sleeping arrangements on relationship satisfaction and overall well-being.
