To sleep well, do not sleep alone!

Does sleeping with your partner allow you to sleep well? The question then arises as the majority of adults sleep with them. Researchers at the University of Arizona show in a recent study that people who sleep with their romantic partner have a higher amount and quality of sleep, a reduced risk of sleep apnea, and less severe insomnia. It would also have an effect on mental health. Explanations.

Sleep well, a primary need

We spend almost a third of our lives at to sleep. Sleep plays a crucial role in many biological functions. Yet to date, nearly a third of French people are affected by one sleep disorder. Indeed, 16% of the population suffers frominsomnia chronic and other conditions such as sleep apnea or the restless legs syndrome are added.

However, poor sleep has an impact on overall health. Studies have shown that one poor sleep quality increases the risk of cardiovascular disease,obesity and of diabetes, cancers and accidents of everyday life. These consequences push research to better understand the impacts of biological, psychological, and social mechanisms on sleep quality.

Sleeping with a partner allows you to sleep well

Although many adults do not sleep alone, the link between bed sharing and bedridden sleep quality is poorly known. Thus, a study by researchers at the University of Arizona explores whether sharing a bed impacts the duration and quality of sleep but also, more broadly, sleep quality. mental health.

To conduct this study, the scientists collected questionnaires completed by more than 1,000 adults of working age. They cover:

  • The number of nights spent with someone, be it a love partner, a child, a pet, or another family member;
  • The number of insomnias;
  • The amount of hours of sleep;
  • The duration of sleep;
  • The risk of sleep apnea.

The results of this work, published in the journal Sleepshow that compared to people sleeping alone, sleeping with someone:

  • Decreases the risk of severe insomnia;
  • Reduces fatigue;
  • Allows you to sleep longer.

Specifically, the study reveals that sleeping with a romantic partner has clear benefits over the sleep quality. Indeed, these people report falling asleep faster, having a lower risk of sleep apnea, a reduction in the severity of insomnia, and an overall improvement in sleep quality.

Effects on mental health

In addition, the study shows that sleeping with a partner has a positive effect on mental health. Indeed, participants report lower levels of depression, anxiety, and stress than those who sleep alone. They also report greater social support and overall high satisfaction with their lives and relationships.

When it comes to sleeping with a child, the results are mixed. The results show that parents who sleep with their child suffer from more severe insomnia, loss of quality control of their sleep, and are more exposed to stress.

Very few studies have previously investigated the impact of sleep alone or accompanied on sleep quality. This work suggests that to sleep well, it is best to sleep with your partner.
