Single vs couple. Who sleeps better?

Adults who share a bed with couples have less insomnia, less fatigue, and more sleep time, according to a study.

Researchers at the University of Arizona in the U.S. studied about 1,000 adults to find out the sleep and mental health conditions of people sleeping alone or with someone. Through the survey, the researchers collected information on who the participants shared their beds over the past month and how often they were. Insomnia severity index, fatigue severity scale, and sleep duration were used to measure sleep quality, and PHQ9 depression score and GAD7 anxiety score were used for research analysis to evaluate mental health.

As a result, people who slept in the same bed with adult partners had less insomnia, less fatigue, and more sleep time than those who slept alone. The stronger the trust with the partner, the higher the quality of sleep. In addition, they had low levels of stress, depression, and anxiety. Sleeping with someone also helped mental health. But when someone was a child, they had conflicting results. Participants who slept with their children showed more insomnia and stress.

“In the past, humans have tended to sleep in groups around fires, so people may feel safer when they are in bed with someone,” study author Michael Granner said. “This trend seems to have been reflected in the research results.”

The study was recently published in the journal SLEEP and presented at a meeting of the Associated Professional Sleep Societies. Single vs couple
