I closed the windows and doors to my bedroom last night before bed. I woke with a crown headache around 4. It was too stuffy in the room as well, I opened the window and went back to bed. I woke two hours later fine and dandy.
Is it possible that my breath and perspiration are so toxin laden that with a closed window and door I am breathing in the toxins I am throwing off and that is what gave me a headache?
