One result of the loss of the thirst feeling as we age is weight gain. The thirst sensation is often confused with hunger. Eating food when the body really needs water raises the levels of sugar concentration in the blood. Weight gain can bring a whole other host of ailments. By the time the thirst-confused individual does drink, they have been dehydrated far too long. Since we do not associate many ailments with thirst, we do not feel the need to drink any more than a glass here and there. However, most bodies need more than a couple glasses in a day. The result is chronic dehydration. It is not enough to kill a person right away; just enough to keep them deficient in fighting off immune system attacks and bodily dysfunction. Histamine is an emergency substance to regulate water to the important areas of the body, but it also will do some long-term damage. Histamine is not meant to be released all the time.
Dr. Batmanghelidj shares his opinion: “It seems to me that the loss of the thirst sensation is an adaptive process to false information that water is not available because we don’t drink it. If the body is once again conditioned to regular and adequate water intake, however, the thirst sensation becomes sharp and the urge to drink becomes strong. The body begins to indicate water shortage more forcefully.” Rehydration is a slow process. For all the cells to become hydrated again it will take a few days.
