in addition, older people of the house would not have explored less of a feeling of thirst – why this is so, it should be last, says Heppner. “You need to drink in the higher age is more of a timetable than to thirst.”

“Healthy people drink when thirsty, automatically as much as you need to compensate. But in the case of older or heart sick people the feeling of thirst may not be properly intact, so that you will not drink sufficient, and the fluid loss is not compensated for,” warns Prof. Andresen of the German heart Foundation. “If in such a Situation, by an additional intake of water, drugs driving a stronger fluid loss, decreases the volume of blood in the vessels: the blood pressure drops, and it can get especially when getting Up from sitting or lying Position to a circulatory collapse with brief loss of consciousness.”
