WATER: ESSENTIAL FOR GOOD HEALTH



audio clip

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.


Going without water for a long period of time:

  • 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 at its best, water that is lost in urine, stool, perspiration, and respiration needs to be replaced daily.


The average person should drink 6 to 8 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 illness from losing body water. Any person who has severe diarrhea, vomiting, or perspiration is also at risk for water loss or dehydration.


People in hot climates, particularly extremely dry or humid climates, can use up 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!
