Postpartum recovery window may play a critical role in maternal aging and long-term health

In many studies, it appears that women who have more children have a higher risk of heart disease and a shorter life span, but this effect is inconsistent across populations and no good explanation for it exists. Against this backdrop, new tools to assess biological age—the age reflected by one's biological state, rather than simply the number of years they have been alive—have revealed that pregnancy temporarily elevates biological age, while postpartum recovery can return it closer to baseline.
