Drinking fluids serves a range of purposes in our bodies: removing waste through urine; controlling body temperature, heart rate, and blood pressure; and maintaining a healthy metabolism.
- Without water, the body begins to shut down. Symptoms of severe dehydration include altered behavior: severe anxiety, confusion, or not being able to stake awake; faintness that is not relieved by lying down; an inability to stand or walk; rapid breathing; a weak, rapid pulse; and loss of consciousness.
- Dehydration occurs when your body loses too much fluid. This can happened when you stop drinking water or lose large amounts of fluid through diarrhea, vomiting, sweating or exercise. Dehydration can occur in anyone of any age, but it is most dangerous for babies, small children, and older adults.
