The most vital substance for a healthy mind and body is water.
Age-related changes make older people more prone to dehydration. Renal function and sensitivity to anti-diuretic hormone (ADH) decrease in some older people. Sense of thirst also appears to be reduced, even in healthy older people. Decreased mobility, confusion or dementia and pathological conditions such as hypertension, heart and renal disease make older people highly sensitive to fluid and electrolyte imbalances.
Dehydration makes people tired, cranky and stiff-jointed. It can make it harder to be patient with others. It can bring on headaches, nausea, aches, cramps and other more serious physical ailments. Severe dehydration can cause seizures, coma or death.
