Self-control or social control - what determines sleep hygiene in bed-sharing couples?

Area of Science:

• Sleep Science
• Behavioral Psychology
• Relationship Dynamics

Background:

• Sleep hygiene is crucial for overall health and well-being.
• The impact of intimate partners on sleep patterns is an under-researched area, particularly concerning the duration of shared sleeping arrangements.
• Understanding factors influencing sleep hygiene can inform interventions for sleep disturbances.

Purpose of the Study:

• To examine how intimate partners influence sleep hygiene.
• To investigate the temporal aspects of co-sleeping on sleep hygiene.
• To identify differential predictors of sleep hygiene in co-sleeping versus individual sleeping arrangements.

Main Methods:

• A cross-sectional study involving 102 participants (co-sleepers and individual sleepers).
• Data collected via in-lab, digital self-report surveys.
• Assessed sleep hygiene, sleeping arrangement duration, self-control, depressiveness, and sociodemographics.

Main Results:

• The positive impact of co-sleeping on sleep hygiene demonstrates a time-dependent relationship, plateauing after approximately one year.
• Individuals in co-sleeping arrangements for over one year exhibited significantly better sleep hygiene compared to shorter-term co-sleepers or individual sleepers.
• Continuity of the sleeping arrangement for over one year was a strong predictor of sleep hygiene in co-sleepers, while self-control was the primary predictor for individual sleepers.

Conclusions:

• Habitual sleeping arrangements, especially long-term co-sleeping, significantly influence sleep hygiene.
• Insomnia treatment strategies could be enhanced by considering patients' sleeping arrangements.
• Consistent co-sleeping routines may promote better sleep hygiene over time.
