Regularly caring for grandchildren may reduce the risk of developing dementia in older adults. This conclusion was reached by Chinese scientists after analyzing data from over 10,000 individuals aged 50 to 79. According to a study published in JAMA Network Open, those who looked after their grandchildren for up to 39 hours per week were 24 percent less likely to face dementia compared to those who did not provide such care at all.
The research indicated that grandparents who regularly assisted with childcare tended to use mobile phones and the internet more often and reported feeling less lonely. These three factors – digital activity and social connections – partially explain the observed reduction in risk. Together, they accounted for nearly 37 percent of the protective effect.
However, constant involvement in grandparenting, equivalent to a full-time work week, did not show a noticeable impact on cognitive health. The scientists suggest that an excessive workload could lead to stress and fatigue, potentially neutralizing any possible benefits.
The authors emphasize that maintaining social connections and learning to use digital technologies can be an accessible strategy for preventing dementia. They highlight regular interaction with grandchildren as an important resource for preserving mental clarity and vitality in older age.
Separately, scientists have previously established that a healthy diet can be a powerful weapon against dementia. A diet rich in vegetables, fish, and whole grains has been shown to reduce the risk of the disease by 28 percent.
