About this listen
Pregnancy isn’t just about a baby bump—it’s also a massive hormonal and physiological shift, including how the body regulates temperature.
In this episode of Mommy Brain Revisited, I’m joined by Dr. Rosie Brown, a Senior Lecturer and Group Leader at the University of Otago in New Zealand. We dive into the hormone prolactin—its role in motherhood and the brain—and explore her team’s groundbreaking research on how prolactin helps regulate body temperature during pregnancy. Tune in for a fascinating conversation on all things prolactin and parenting!
