Becoming a grandparent may bring more than joy and laughter—it could also improve physical and mental health, according to medical experts who say the transition offers a renewed sense of purpose and vitality for older adults.
“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. Carney, who has treated older adults for nearly three decades, said both research and her own clinical experience highlight the importance of purpose, activity, and gratitude in aging well.
The positive impact of grandparenting is seen across cultures. “Many people say becoming a grandparent can ‘keep you young,’” said Dr. Kanramon Watthanasuntorn, medical director at the Center for Better Aging at St. Bernard Hospital in Chicago. “The joy, energy, and renewed sense of purpose grandchildren bring can be especially meaningful for aging populations.”
Grandparenting has been linked to better self-reported health, lower rates of loneliness, and greater happiness, according to studies cited by Dr. William Hung of Mount Sinai’s Icahn School of Medicine. “Some of my patients beam with pride when talking about their close relationship with a grandchild,” he said, noting that the benefits are most pronounced when caregiving remains supportive rather than stressful.
On a biological level, interactions with grandchildren stimulate the release of hormones such as oxytocin and endorphins, which reduce stress and promote well-being. The responsibilities of caring for or playing with children also encourage physical activity, whether through walks to the park or active play. Research suggests that grandparents engaged in childcare are more physically active and less sedentary than their peers, contributing to better long-term health outcomes.
The mental benefits are equally significant. Engaging in storytelling, helping with homework, or navigating new technology with grandchildren challenges the brain and may sharpen cognitive function. Studies indicate that grandparents, particularly women, often perform better on cognitive measures when actively involved in childcare.
Social connections formed through grandparenting also play a role in longevity. Building bonds with grandchildren often leads to stronger family ties and greater community involvement. “The social-support network is vital for health and longevity,” Carney said, adding that staying socially engaged reduces risks of isolation and cognitive decline.
For older adults without grandchildren, similar benefits can be achieved through intergenerational community programs, mentoring, or volunteering. Activities that provide purpose and connection—whether tutoring, mentoring, or caring for relatives’ children—help reduce loneliness and foster well-being.
Ultimately, experts say the role of a grandparent is not only about caring for children but also about modeling healthy behaviors. “Grandparenting is an opportunity to show younger generations the value of healthy eating, physical activity, and lifelong learning,” Carney said. “In doing so, grandparents strengthen their own health while leaving a legacy of love and guidance.”
