As the heat will be there as a consequence, it shows in the complexion – often as Roseacea (with Stomach Yin heat) and/or a general reddening of all upper body – face, bloodshot eyes and a heat that is often emotionally explosive, along with headaches and migraines intensifying with lack of fluids/exposure to chemicals that would need the water to dilute them.
