COLD AIR CONDITIONING... My husband keeps our house at 68, with ceiling fans. My headaches started and then it got worse. Couldn't think or remember where I was going. When I would work outside in the garden, in the heat, the headaches would go away. One night at 1am it was so cold I went and got in my car and turn the heat on. The headache went away. It affected our dog, he was having problems breathing. I also, netted my nose with peroxide and water. It's getting much better. If I go to a building, like today at my vets. It was cold, my head started hurting. The woman next to me said the same thing. We went outside and waited. This is what worked for me.
