Does working out affect breast milk supply?

The Relationship Between Exercise and Breast Milk Supply
For new mothers, the journey of breastfeeding often comes with a myriad of questions, particularly regarding lifestyle choices like exercise. One common concern is whether working out can affect breast milk supply. The good news is that research and expert opinions suggest that moderate exercise does not negatively impact milk production.
Exercise and Milk Production
Numerous studies and expert analyses indicate that engaging in regular physical activity does not diminish breast milk supply. According to the American College of Obstetricians and Gynecologists (ACOG), regular aerobic exercise during lactation has no adverse effects on milk production, composition, or the growth of infants. In fact, it can enhance maternal cardiovascular health, which is beneficial for both mother and baby.
Moreover, historical evidence supports the idea that many women have successfully breastfed while engaging in physically demanding work. This suggests that the body is capable of balancing the demands of exercise and lactation.
Moderation is Key
While the consensus leans towards exercise being safe for breastfeeding mothers, experts recommend sticking to moderate forms of exercise. Activities such as walking, strength training, and cycling are encouraged, as they allow mothers to maintain fitness without overexerting themselves. Intense workouts may lead to temporary increases in lactic acid levels in breast milk, but this change is typically not noticeable to infants, who often nurse without any issues.
Hydration and Nutrition
It’s crucial for breastfeeding mothers to stay hydrated and meet their increased nutritional needs, which can range from 330 to 400 additional calories per day depending on the stage of lactation. Failing to do so can potentially impact milk supply, but this is more related to overall energy balance rather than exercise itself. Stress and dehydration are known factors that can decrease milk supply, underscoring the importance of a well-rounded approach to health during this period.
Conclusion
In summary, working out does not adversely affect breast milk supply, and many mothers can safely incorporate exercise into their routines. The key lies in moderation and ensuring that nutritional and hydration needs are met. As mothers navigate the challenges of breastfeeding, they can feel confident that staying active is not only permissible but can also contribute positively to their overall well-being.
