(MEDICAL NEWS) – As couples grow old together, their interdependence heightens. Often, they become each other's primary source of physical and emotional support. Long-term marriages have a profound impact on health and well-being, but benefits depend on relationship quality.
A new study from the University of Illinois examines the dynamics of long-term relationships through spatial proximity. The researchers find that when partners are close to each other, their heart rates synchronize in complex patterns of interaction.
"We were looking for more objective ways to measure relationship dynamics, and we know that being around other people has psychological benefits. So, physical proximity seemed liked a strong candidate."
