Breastfeeding is not only beneficial for childs but also benefit for moms hearts.

Studies have long touted the benefits of breastfeeding for infants, including stronger immune systems and lower risk for asthma, obesity and type 2 diabetes.

But babies aren't the only ones benefiting: Nursing also appears to provide health benefits for moms.

Research suggests women who breastfeed have a lower risk of breast and ovarian cancers. The longer women nurse, whether with one child or over the course of several, the lower their risk.

Release of oxytocin

More recently, studies have found that breastfeeding also helps the mother's heart – beyond nurturing its bond with baby, that is.

Breastfeeding has been associated with a lower risk of developing diabetes, high cholesterol, high blood pressure and heart disease.

But the mechanics behind how that might happen is up for debate.

It's possibly linked to the release of the hormone oxytocin, which relaxes blood vessels, said Dr Nieca Goldberg, medical director of the Joan H. Tisch Center for Women's Health at New York University.

"It may also very well be that many breastfeeding mothers have a healthier lifestyle overall," she said.

These women may eat healthier, exercise regularly and "they make healthier choices in general, not only for their babies but themselves," she said.
