Cooler environments after birth: new brain research sheds light for Thai mothers
A new study from a leading medical research center explains why many new mothers may prefer cooler surroundings after childbirth. Although conducted in mice, the research offers insight into how pregnancy and birth can alter temperature regulation. The findings could deepen understanding of maternal physiology for Thai readers and beyond.
Published in Molecular Metabolism, the study shows postpartum female mice develop a clear preference for cooler settings for more than four weeks after weaning. The researchers pinpoint neural changes in estrogen receptor alpha (ERα) neurons in the brain’s preoptic area as key drivers of this shift. In postpartum mice, these neurons become less responsive to warmth and more responsive to cold, reshaping environmental preferences.
