Becoming a Grandparent Can Boost Physical and Mental Health, Experts Say

When a new baby joins a family, the effects ripple beyond the parents: clinicians and medical literature say becoming an involved grandparent can yield measurable health benefits for older adults.

Geriatric specialists say the transition to grandparenting often brings more physical movement, social engagement and a renewed sense of purpose—factors long associated with healthier aging. "Being an involved, active, supportive, storytelling grandparent has potential healthy aging benefits," said Dr. Maria Carney, chief of geriatric and palliative medicine at Northwell Health and co-author of The Aging Revolution: The History of Geriatric Health Care and What Really Matters to Older Adults. Carney, who has worked with older patients for nearly 30 years, said both published studies and her clinical experience point to common themes: feeling purposeful, staying active and practicing gratitude.

Health experts say the practical activities of grandparenting—playing on the floor, chasing toddlers, helping with childcare and sharing stories—can increase daily movement and social contact in ways that reduce isolation and stimulate cognition. Those changes align with established recommendations for healthy aging, which emphasize physical activity, meaningful social ties and cognitive engagement.

Researchers who study aging note that the quality and intensity of grandparent involvement influence outcomes. Active, supportive roles that foster positive interactions and storytelling appear most likely to confer benefits, according to Carney and a review of the literature. The experience may also promote emotional well-being; many older adults report joy, renewed energy and a strengthened sense of purpose after becoming grandparents, phenomena sometimes described cross-culturally as "keeping you young."

Clinicians caution that not all grandparenting experiences are the same. The potential advantages described by Carney and others are associated with engagement that is voluntary and positive. Heavy caregiving responsibilities, strained family relationships or high stress levels can blunt or reverse potential benefits, according to geriatric care specialists.

The physician perspective echoes findings in gerontology that link purposeful activity and social connection to longer-term health outcomes. Interventions that increase social participation and regular physical movement are commonly recommended in geriatric practice, and family roles that facilitate those behaviors are seen as one way older adults may maintain function and emotional health.

As populations age and family structures evolve, clinicians say recognizing the role of intergenerational ties could inform broader public health strategies. Encouraging supportive grandparenting, facilitating safe opportunities for older adults to engage with grandchildren and addressing barriers to involvement—such as mobility limitations or geographic distance—are among approaches experts suggest for harnessing the potential benefits.

For many older adults, the arrival of a grandchild marks a visible change in daily life: less time on the couch, more play and storytelling, and renewed social connection. Medical experts say that, when the role is active and supportive, those changes can contribute to healthier aging by promoting movement, reducing isolation and fostering emotional well-being.
