Sleep quality shapes jealousy in insecure relationships

Summary: A new study reveals that poor sleep quality is linked to an increase in jealousy in people with high anxiety for relationships. The anxious attachment, marked by insecurity and low self -esteem in relationships, was associated with the worst quality of sleep.

It is important to note that the link between poor dream and jealousy only remained true for people with high levels of attachment anxiety. These findings suggest that a person’s attachment style can influence how sleepy affects emotional responses.

Key facts:

A new study that will be presented at the annual meeting Sleep 2025 found that poor sleep quality is related to the insecurity of the relationship, which moderates the effect of sleep quality on daily feelings of jealousy.

The results show that anxious attachment, which implies difficulties with trust and low self -esteem in relationships, was related to poor sleep quality. The study also found that the poor quality of sleep was associated with more daily feelings of jealousy, but this effect was only significant for those with high levels of attachment anxiety.

“Interestingly, the poor dream was not uniformly related to all the negative socio -emotional results,” said Giovanni Alvarado, principal author and doctorate candidate at Montana State University in Bozeman, Montana.

“This suggests that the attachment style could shape the emotions most affected by sleep quality.”

According to the American Academy of Sleep Medicine, sleep is essential for health. The AASM recommends that adults sleep 7 or more hours per night regularly to promote optimal health. In addition to the appropriate duration, healthy sleep requires good quality, appropriate time and regularity, and the absence of sleep disorders or disorders.

The study involved 68 young adults who completed questionnaires about sleep and relationships. They also completed daily self -reports capturing experiences of emotions and social behaviors for a period of two weeks.

According to Alvarado, the study underlines the complex link between sleep and relationships.

“People with anxious attachment, or those who fight with insecurity in relationships, can be especially vulnerable to feelings of envy and jealousy when they are deprived of sleep,” said Alvarado.

“This helps us understand why some people may have more difficulty navigating in social situations when they are tired and can inform more specific interventions that consider an individual’s relationship style when addressing sleep problems.”
