[YEA] Acid reflux is sometimes a symptom of dehydration. The body turns on histamines in order to protect the BRAIN from dehydration; according to Dr. Batmanjelidh, "Dr. Batman" "The Water Cure", the histamine closes off water and function from different body parts in order to preserve all the available water for the protection and use of the brain.
In the stomach this can lead to sensations of burning - see www.watercure2.com. the actual explanation of the mechanism is found in the book - I don't remember exactly how it works.
I have avoided salt most of my adult life, thinking it was bad for you; I found it difficult to even swallow water except for when I used to jog when I was young.
After reading "The water cure"I forced myself to drink water with a little salt in it - no more fatigue, no more constipation, tons of energy. When I get a little heart burn I just drink water - 2 to 3 glasses and it's gone.
