Cause of Brain Fog
AC... working in artificial Air Conditioning that keeps you cold all day, and night. My husband had AC down on 73, a ceiling fan and a side fan. I would wake up frozen with a horrible headache. When I would leave the house or go outside, I started feeling better, no headache. Then one morning it was so cold my face and arms were frozen. I realize what was happening to me and my dogs.
