The potentially lasting implications of day-to-day couple conflict on physical and mental well-being are revealed in a study published today in the journal Personal Relationships (June 17, 2011). The study found that all participants across the sample as a whole experienced sleep disruption after conflict. Conflict was also found to have repercussions for next-day mood. The results of this study have significant implications for the greater understanding of how routine relationship experiences influence emotional and physical health over time. “We already know from prior research that people in stable, happy marriages experience better overall health than do those in more conflicted relationships,” said Professor Hicks. “We can now further conclude from our current research that individuals who are in insecure relationships are more vulnerable to longer-term health risks from conflict than are others.”
