How many children a woman has—and when she has them—may significantly impact her biological aging and overall lifespan. That is the primary takeaway from a decades-long study of nearly 15,000 twins, which tracked participants from 1975 to the present day to examine the link between family size, pregnancy timing, and longevity.
The researchers found that women with two to three children tended to live the longest. However, the data suggests that timing is just as crucial as the number of children:
Optimal Timing: Pregnancies occurring between the ages of 24 and 38 were linked to more favorable aging patterns.
The Extremes: Women with four or more children showed signs of faster biological aging and shorter lifespans.
The Childless Gap: Unexpectedly, women with no children also appeared to age more quickly. Researchers noted this could be due to underlying health or lifestyle factors that the study was unable to fully control.
To verify these findings, researchers used blood tests to analyze DNA changes and calculate biological age. The results mirrored the mortality data: women at both ends of the spectrum—those with many children and those with none—appeared biologically older than their chronological age.
While the study’s authors emphasize that these findings show correlation rather than causation—and should not dictate personal reproductive choices—the data lands in a complicated social landscape. For many women, the pressure to “have it all” by a certain age creates a heavy psychological burden.
Actress Tracee Ellis Ross, often celebrated for her own graceful aging, has been a vocal critic of the stigma facing single, childless women. Speaking at the New York Times Well Festival last year, Ross shared how societal expectations once limited her own sense of self.
“It undermined my sense of worth and self and joy until I realized it was somebody else’s idea,” Ross said, noting that she still occasionally finds herself caught in those traditional narratives.

Ross also addressed the “trad-wife” movement—a growing trend of young women prioritizing homemaking and large families over careers. While the study might suggest a biological “sweet spot” for childbearing, Ross argues for a broader definition of fulfillment and “mothering.”
“I do believe that I mother all over the place,” Ross explained. “I do believe that I do very valued things in the world and for people that I care about and love.” Her perspective serves as a reminder that while science can track biological markers, it cannot measure the value of a life lived outside traditional benchmarks.

While you can’t change your reproductive history, you can influence how your body ages today. Here are a few ways to support your biological “clock”:
Prioritize “Biological” Rest: Chronic stress accelerates cellular aging. Incorporate mindfulness or deep-breathing exercises to lower cortisol levels.
Focus on Nutrient Density: Regardless of how many people you are cooking for, a diet rich in antioxidants (berries, leafy greens, nuts) helps combat the oxidative stress linked to faster aging.
Build Your “Village”: The study hinted that lifestyle factors impact the longevity of childless women. Combat isolation by investing in a strong social or “chosen family” network, which is proven to increase lifespan.
Stay Physically Active: Regular resistance training helps maintain bone density and muscle mass, two of the most critical markers for aging well in women.
Define Your Own Value: As Tracee Ellis Ross suggests, mental well-being is tied to self-worth. Rejecting societal pressures can reduce the psychological “wear and tear” that contributes to feeling—and looking—older.
