Staying well-hydrated is an important aspect of overall health. Drinking too few fluids, taking diuretics or laxatives or having symptoms or conditions that flush fluid from your body, such as diarrhea, vomiting or uncontrolled diabetes, can cause dehydration -- the state in which your body does not contain enough fluid for proper function. In many cases, dietary steps can help prevent or reverse dehydration. For best results, seek specified guidance from your doctor or dietitian.
Function of Water
Water, which contributes about 60 percent of your weight, is your body's main chemical component, according to MayoClinic.com. Every system in your body, including your tissues, organs and cells, require water. It helps flush toxic substances out of your organs, such as your liver and kidneys, carries nutrients to your cells and helps maintain moistness in your throat, ears and nose. If you consume too few hydrating substances, which contain water, you can develop dehydration.
Dehydration Effects
Mild dehydration is common and typically remedied by drinking water or other hydrating fluids. If you do not replenish lost fluids, you may experience a broad range of symptoms, ranging from thirst, dry mouth and headache to more severe symptoms, such as nausea, fever, excessive sweating and sunken eyes. In rare, but serious, cases, loss of consciousness is possible, according to the University of Maryland Medical Center. Treatment for advanced dehydration may include intravenous fluids and hospitalization.
Proper Fluid Intake
People's fluid needs vary, and no single formula for water intake exists, according to MayoClinic.com. Some professionals recommend drinking at least 64 oz., or eight 8-oz. cups, of water per day. Others suggest drinking until your urine appears pale or translucent. If you are dehydrated, you may require more fluids until you reach normal hydration levels. Spending time in hot weather or exercising intensely increase your fluid needs because of fluids lost through sweat.
Hydrating Foods and Beverages
In addition to water, numerous other foods and beverages promote hydration. Other hydrating liquids include herbal tea, broth-based soups, low-fat cow or soy milk, pure juices and sports drinks, which may be particularly helpful in restoring electrolytes -- natural salts in the body that promote organ and muscle function -- in athletes after lengthy exercise, according to the University of Illinois Extension. Fruits and vegetables are also water-rich. Grapefruits and carrots, for example, consist of about 90 percent water.
