New Research Suggests Giving Birth Actually Reverses Biological Aging

The study, conducted by a team of researchers and led by Dr. Kieran O'Donnell from Yale University, delves into the complex relationship between pregnancy and biological age. For those unfamiliar with the concept of biological age, it’s a measure of how well our bodies are aging internally.

Dr. Mark Hyman, a renowned functional medicine expert, discusses biological age often, offering insights into its potential implications for our health and longevity and how we can measure it with a combination of biomarkers and health indicators such as inflammation, insulin sensitivity, cardiovascular health, and even cognitive function.

You can read more about biological age here, but by tracking over a hundred women through their pregnancies and postpartum periods, the researchers made a fascinating discovery: While pregnancy temporarily accelerates biological aging, the postpartum period holds the key to a remarkable reversal.

Throughout pregnancy, the physiological stress experienced by women was found to accelerate their biological age by several years, but within just three months postpartum, researchers observed a significant decrease in biological age, with some individuals experiencing a reversal of up to eight years.

Despite the challenges and changes that pregnancy brings, it appears to bestow mothers with yet another gift: the potential for turning back the biological clock.

What's even more intriguing is the role that breastfeeding plays in this process. Women who breastfed after delivery exhibited an even greater reversal in biological age, highlighting the potential benefits of breastfeeding beyond infant nutrition.

However, not all factors contribute equally to this reversal. A higher body-mass index was found to impede the process, indicating that metabolic health also plays a crucial role in harnessing the rejuvenating effects of pregnancy.

Dr. O'Donnell emphasizes that while these findings are promising, there are still many unanswered questions. It remains unclear whether pregnancy offers a net benefit in terms of biological age or if the postpartum recovery merely restores the body to its pre-pregnancy state. Moreover, the long-term implications of these effects on maternal health and whether they accumulate over successive pregnancies warrant further investigation.

Nevertheless, in a cultural moment where motherhood is often postponed for various reasons, this study serves as a reminder of the many natural, positive, and healthy aspects of becoming a mother. Many in the industrial-pharmaceutical complex and their media allies like The Washington Post will continue to push the narrative that pregnancy is too demanding or dangerous for women, but the truth is that we are far more capable than we realize, and our bodies can do amazing things.
