Water is a major component of the tissues and cells of the body. Without water the human body will survive only a few days. No other nutrient deficiency has such profound effects.
A prolonged absence of water:
- lowers blood pressure
- weakens the heart and
- shuts down the kidneys
Water is the major component of blood and urine and is also found in gastrointestinal juices, perspiration, and even the joints of the body.
The body can store water, but only on a very limited basis. For the body to function optimally, water losses from urine, stool, perspiration, and respiration need to be replenished daily.
The average person should consume 8 to 10 eight-ounce glasses of water each day. Although water is the best "thirst-quencher," other liquids (such as juices, milk, sodas, and teas) can help meet fluid needs. High sugar and high caffeine beverages are not the best choices because they can lead to increased urination.
The elderly and young children are at the highest risk for a water deficiency. Any individual who is experiencing prolonged diarrhea, vomiting, or perspiration is also at risk for water deficiency or dehydration.
People in hot climates, particularly extremely dry or humid climates, can deplete their water reserves. If you experience muscle cramping, nausea, headache, or dizziness, you may be dehydrated.
Be water smart. Drink plenty of fluids each and every day!
