It’s science: Babysitting your grandkids helps you live longer 🙌

It's been a long week. You're stressed out from mama duties. You want to take a break over the weekend, but you don't want to burden your parents by asking them to babysit. They don't mind, of course, because they adore your little bundle of joy. But there's another good reason to ask: Science shows grandparents who watch their grandchildren add an average of five years to their lives.

According to a study published in Evolution and Human Behavior, grandparents who babysit or provide some level of care to their grandkids had lower risks of death over a 20-year period than older adults who did not take on caregiving roles. That's according to data analyzed from the Berlin Aging Study, which tracked the health outcomes of more than 500 people ages 70 and older.

Why, exactly, does babysitting have such health benefits for grandparents?

Dr. Ronan Factora of the Cleveland Clinic, who was not involved in the study, says it's because as you age, “You want to stay physically active. You want to stay socially engaged. You want to be cognitively stimulated; and all those things allow you to age well."

This is not the first link made between babysitting and longevity among grandparents: Researchers behind the 2016 study published in Evolution and Human Behavior came to a similar conclusion after analyzing previous data from the Berlin Aging Study. According to that study, grandparents who babysat their grandkids lived five years longer, on average, than those who did not.

The health benefits of babysitting don't only apply to grandparents

The Evolution and Human Behavior study also found that older adults who helped care for unrelated children also had years added to their lives. Same goes for people without children: According to researchers, childless adults who provided childcare lived an average of three years longer.

That doesn't mean you should give your children over to your parents full-time, though. Although moderate caregiving has its health benefits, previous studies have found that informal caregivers can feel physical and psychological stress from heavy involvement. In turn, they experience negative health outcomes—especially if the caregiver has a history of depression or anxiety.

In other words, it's all about striking the right balance. As Ralph Hertwig, author of the 2016 study, puts it: “Helping shouldn't be misunderstood as a panacea for a longer life."

Daytime naps might last just a few short hours, but they can affect all 24 hours of a child's day. Naps can improve a child's mood and reduce fussiness, crying, whining and tantrums. Studies show that children who nap daily also get sick less often, grow taller and are less likely to be obese when they grow up. Naps enhance attention span and brain development.

Naps can also help make up for any shortage in nighttime sleep. Even a one hour shortage in overall sleep hours can have a negative effect on a child—compromising alertness and brain function and increasing fussiness and fatigue.


There are many ideas for helping a child to take a nap, but the best idea in the world may not work for you if the solution doesn't address the reason that your child won't nap. There is not just one reason that babies and young children refuse to nap—there are hundreds of different reasons.
