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
