Adults who sleep with a partner or spouse tend to sleep better than those who sleep alone. In a new study published in the journal Sleep, researchers at the University of Arizona collected data from over 1,000 adults. They found that people who slept next to their partner most nights reported less fatigue, less severe insomnia, and more time asleep than those who said they never share a bed with a partner. They fell asleep faster and stayed asleep longer after falling asleep. Sleeping with a partner was linked to lower depression, anxiety, stress, and greater social support and satisfaction with life and relationships. On the other hand, adults who slept with their child most nights reported greater insomnia severity, experienced more stress, and had less control over their sleep.
