What factor can negatively influence milk production due to pressure on the milk-making cells?

Excessive pressure in the breast can negatively influence milk production because the milk-making cells, or alveoli, require a certain level of space and pressure to function optimally. When there is inappropriate external pressure, such as from tight clothing or undergarments, it can restrict blood flow and lymphatic drainage, which are essential for maintaining healthy breast tissue and facilitating milk production. This pressure can lead to decreased hormone signaling necessary for stimulating milk synthesis and may even cause discomfort or pain for the breastfeeding individual, further complicating the lactation process.

In contrast, long feeding durations, frequent feedings, and properly fitting bras typically support healthy milk production by promoting milk removal and preventing issues like engorgement or blocked ducts. Frequent feedings, for instance, help establish and maintain milk supply by signaling the body to produce more milk in response to demand. Therefore, managing pressure in the breast is crucial for optimal lactation.
