“Results show that those who shared a bed with a partner most nights reported less severe insomnia, less fatigue, and more time asleep than those who said they never share a bed with a partner. Those sleeping with a partner also fell asleep faster, stayed asleep longer after falling asleep, and had less risk of sleep apnea. However, those who slept with their child most nights reported greater insomnia severity, greater sleep apnea risk, and less control over their sleep.
Researchers also found that sleeping with a partner was associated with lower depression, anxiety, and stress scores, and greater social support and satisfaction with life and relationships. Sleeping with children was associated with more stress. Sleeping alone was associated with higher depression scores, lower social support, and worse life and relationship satisfaction.”
