Women’s Breasts Keep Babies Warm Even When Rooms Turn Cold, Study Finds — 5ch Fires Back: ‘Hard to Buy the Evolution Angle When They Sagged Long Before Bras’

The story

Research from Finland’s University of Oulu and colleagues found that during lactation, women’s breasts have a “cooling resistance” that keeps their temperature from dropping much even as room temperature falls. Even when the room was cooled from 32°C to 27°C, and further down to 18°C, the breast surface temperature dropped by only about 0.1°C on average. Reacting to this Nazology article, 5ch’s Science News+ board saw a mix of responses — some simply accepted it as “a mother’s function,” while others raised the evolutionary question of how breast fullness could be explained from an era before bras existed — before the back half of the thread drifted into the usual raunchy jokes and song references.

The fullness of women’s breasts may have evolved to keep babies warm

Research conducted at Finland’s University of Oulu and other institutions has revealed that during the breastfeeding period, women’s breasts have a strong “cooling resistance” — an ability to hold their temperature even as the room gets cold.

The study showed that even when the room temperature was dropped 5°C, from 32°C to 27°C, the breasts of breastfeeding women fell by only 0.1°C on average, and that this ability still held even at a much colder 18°C.
