The age-old question of whether couples should share a bed or not has garnered new insights. Recent research led by Dr Drews has utilized advanced technology to analyze brain waves, movements, muscle tension, and heart activity of couples to find out if sleeping with partners was beneficial or not. The findings revealed that couples who slept side-by-side experienced increased and less disrupted rapid-eye movement (REM) sleep compared to when they slept separately. REM sleep, known for its association with memory organization, emotional regulation, and problem-solving, plays a critical role in mental well-being. Interestingly, the study also found a correlation between how couples rated their relationships and their sleep synchronization when sharing a bed. Higher relationship satisfaction was linked to better alignment during sleep.However, not all couples reaped the benefits of shared slumber. Furthermore, the research emphasised that partners can disrupt each other’s sleep, particularly if one partner is loud or restless. Dr Patricia Haynes, an associate professor at the University of Arizona, noted that while REM sleep is beneficial, it is not the only crucial aspect of good sleep, slow-wave sleep typically offers more restorative benefits. She highlighted that interrupted REM sleep often correlates with stress-related disorders, suggesting that those accustomed to sleeping with a partner may experience stress when they sleep alone.Complicating the issue, the quality of sleep is subjective and may not always align with the actual quantity or type of sleep one receives. For instance, some studies have indicated that women sleeping with snorers reported decreased sleep quality. Yet, interestingly, the quality of sleep for non-snoring partners didn’t necessarily improve when sleeping alone for one night.Additional factors influencing sleep quality include differences in temperature preferences, work schedules, and bedtime routines. Couples who watch TV or engage in stimulating activities in bed may find their rest impacted negatively.Limb Movements Increased In Couples Sharing The BedDrews's research found that while limb movements increased in couples sharing a bed, these did not necessarily disrupt sleep, indicating that movement alone is not a definitive marker of poor sleep quality. On the other hand, individuals with insomnia may struggle to share a bed, as preoccupations with sleep difficulties can lead to increased disturbances.Ultimately, the decision to sleep with a partner may come down to individual preferences and circumstances. For some, the emotional comfort of sharing a bed enhances sleep quality, while others may find that a good night's rest is best achieved.
