Chronic sensitivity to excessive heat and cold temperatures during breastfeeding is responsible for 17 to 19% of stillbirths. However, these results are based on the minimal data currently available, so expectant mothers should not be concerned; further research is needed. According to environmental scientist Dr. Scott Lieske, the results indicate that women in developed countries will be affected as global temperatures increase.
