Volunteering Linked to Slower Biological Aging and Better Health in Older Adults

New research highlights that volunteering significantly contributes to slower biological aging and improved health among older adults. According to a study reported by Real Simple, older adults who volunteer show healthier cells and reduced biological aging, even after accounting for factors like health status, education, economic standing, and physical activity. Cal Halvorsen from Washington University explains that the benefits of volunteering may stem from social interaction, structured routines, and a strengthened sense of purpose derived from such engagement.

The study measured biological aging through epigenetic age, which analyzes chemical markers in DNA to assess how the body ages. Volunteers contributing between 50 and 199 hours per year, roughly 1 to 4 hours weekly, exhibited the most pronounced health improvements. Additionally, even smaller amounts of volunteering seem to confer benefits.

Volunteering may enhance health by promoting physical activity, reducing feelings of loneliness, and providing mental stimulation, which can help maintain cognitive sharpness as people age. These findings suggest that even a modest commitment to volunteer work could be a practical and effective way for older adults to support their overall well-being and slow the aging process.
