Mothers who choose to breastfeed may be giving themselves a lasting gift that extends far beyond their baby's early months. An encouraging new study published in BMJ Open suggests that breastfeeding could protect mothers from depression and anxiety for up to a full decade after pregnancy, offering hope and validation for nursing mothers everywhere.

Researchers in Ireland followed 168 second-time mothers over 10 years, tracking their breastfeeding experiences and mental health through regular check-ups when their children were 3 months, 6 months, 2 years, 5 years, and 10 years old. By the end of the study, when the mothers averaged 42 years of age, the results painted an optimistic picture for those who had breastfed.

Nearly three quarters of the women, about 122 mothers, had breastfed at some point. The study found that these mothers showed lower rates of depression and anxiety compared to those who hadn't breastfed. Even more encouraging, the benefits appeared to increase with time spent breastfeeding. For every additional week of exclusive breastfeeding throughout a mother's lifetime, researchers observed a 2% lower likelihood of experiencing depression and anxiety.

More than a third of the participating mothers had breastfed for cumulative periods totaling at least 12 months across their children, and these women showed particularly positive mental health outcomes. The average exclusive breastfeeding period lasted about 5.5 weeks, while any breastfeeding lasted around 30.5 weeks.

The Bright Side

While this study adds to growing evidence that breastfeeding offers mental health benefits during the immediate postpartum period, the truly exciting discovery is that these benefits may persist much longer than previously thought. This research suggests that the positive effects of breastfeeding on maternal mental health could extend through a child's entire elementary school years and beyond.

The researchers believe the relationship between breastfeeding and long-term mental health is complex and multifaceted, influenced by various socioeconomic and cultural factors. Successful breastfeeding experiences may provide an early foundation of confidence and well-being that helps protect mothers' mental health for years to come.

The study's authors emphasize that these findings strengthen the case for better breastfeeding support systems. They note that improving breastfeeding rates and duration already improves lifetime health outcomes for both mothers and babies, reduces disease burden across populations, and results in significant healthcare savings. The potential for breastfeeding to also reduce the enormous burden of depression on individuals, families, healthcare systems, and economies makes the argument for robust breastfeeding support even more compelling.

For mothers who are currently breastfeeding or considering it, this research offers an uplifting perspective. The benefits you're providing go beyond nutrition, extending to your own mental wellness for years into the future. And for policymakers and healthcare providers, it's a powerful reminder of why investing in lactation support, education, and resources matters so much for the long-term health of families and communities.
