Heat extremes seen raising incidence of congenital abnormalities
- Projections for 2025-2035 indicated that incidence of congenital heart defects could more than double in the Midwest, where the frequency of "extreme heat events" in summer was predicted to rise more than three-fold

The word VITAMIN does not occur once in the study
VitaminDWiki hypothesis
Extreme Heat events ==> pregnant women stay indoors ==> less vitamin D ==> increased incidence of many birth defects, such as CHD
Study noted increased CHD is especially true for Heat Events occurring in the spring (when the body is used to restoring vitamin D levels)
- Congenital heart defects twice as likely if low vitamin D while pregnant – Feb 2018
- Preeclampsia increased risk of Congenital Heart Defects by 60 percent (vitamin D not mentioned) Oct 2015
- Congenital Heart Disease is associated with gestational diabetes in first trimester (need Vitamin D and Omega-3 early) Dec 2017
- Ensure a healthy pregnancy and baby - take Vitamin D before conception has the following chart
- Healthy pregnancies need lots of vitamin D has the following summary
Most were taking 2,000 to 7,000 IU daily for >50% of pregnancy
