A new study has found that older adults who play an active role in their grandchildren's lives live, on average, about five years longer than those who don't. Experts say the physical, emotional, and sense of purpose that comes from caring for grandchildren can have a powerful impact on longevity and overall well-being.

Why it matters

As the population continues to age, understanding the factors that contribute to healthy longevity is increasingly important. This research suggests that strengthening intergenerational bonds and providing older adults with a sense of purpose through grandparenting could be an effective way to support healthy aging.

The details

The study found that the benefits of spending time with grandchildren go beyond just emotional connection. Keeping up with grandchildren keeps older adults physically active, which improves blood flow and overall health. Additionally, having tasks, being involved in the family, and knowing someone depends on you can provide a powerful sense of purpose and belonging that positively impacts mental and emotional well-being.

  • The study was published in April 2026.
