Latest findings unveil that people who help care for others tend to live longer than those who do not. The researchers found that grandparents who take care of their grandchildren, on average, lived longer, compared to grandparents who did not. The researchers conducted survival analysis of over 500 people over the age of 70.
The findings of the study reveal that this type of caring had positive effects on the seniors, giving them more years of living. Half of the grandparents who cared for their grandchildren were still alive 10 years after the initial study interview, which took place in 1990. The same findings were seen among seniors who did not have any grandchildren but helped their own children. Caregiving benefits were not limited to the family – seniors who provided emotional support for friends and others also had a longer life.
“It seems plausible that the development of parents’ and grandparents’ prosocial behavior toward their kin left its imprint on the human body in terms of a neural and hormonal system that subsequently laid the foundation for the evolution of cooperation and altruistic behavior towards non-kin,” concluded first author Sonja Hilbrand.
