Temperature-Changing Breasts

A woman's breast changes temperature in response to the temperature of anything touching it. Something cool will make the skin warm up, and something warm will make the skin cool down. This is a useful response to an fevered infant or a baby with a chill. All a mother has to do is hold her baby to her chest and her body will automatically adjust to keep the baby's temperature around 36.9 ºC (98.4 ºF). So, boobs are pretty cool. Or warm, depending on what you need.
