Mothers experience major metabolic adaptations during pregnancy and lactation to support the development and growth of the new life. Although many metabolic changes have been studied, body temperature regulation and environmental temperature preference during and after pregnancy remain poorly understood. Researchers at Baylor College of Medicine and collaborating institutions show in the journal Molecular Metabolism that postpartum female mice develop new environmental temperature preferences and reveal brain changes mediating these changes. In both humans and mice, body temperature increases during early pregnancy, drops to normal temperature during late pregnancy and then goes up again during lactation."
