Why would a shower trigger adrenaline in Dysautonomia Discussion Posted June 7 · Report reply If anybody knows. Since the near fainting/spinning outta control/no balance episode, I take quick showers. Ever since I took one today, I've been suffering for hours and hours. No let up. I believe it's adrenaline. Sweaty palms, extreme anxiety. This isn't the only time it's done it to me. Today has been torture. The only thing I can think of to do is lower the temp of the water. I just wonder why it would go on and on and on. I can't sleep because of it.
