Water is important for digestion and absorption of food. Digestive symptoms such as nausea can be indicative of
need for more water. Constipation, a frequent complaint of elderly Americans is commonly caused by inadequate water intake, says a California nutrition expert.
Joint and muscle stiffness occur as a result of not enough water for lubrication.
Without adequate water, there is stress on cardiovascular system. Blood becomes thicker so heart works harder and circulation is slowed. Many elderly people already have a sluggish circulation.
When circulation is sluggish brain doesn't receive enough oxygen resulting in headaches, dizziness, fatigue, and a loss of mental alertness. A reduction of only 4 to 5 percent in body water will result in a 20 to 30 percent work performance.
Postmenopausal women taking estrogen supplements need to be aware that estrogen acts as a salt retainer. Water is needed to remove excess salt from body.
Some common signs of an inadequate water intake are constipation, dark yellow urine, and dry, sticky mouth caused by decreased salivary gland function says a Harvard physiologist. Everyone needs a minimum of eight 8-ounce glasses of water spaced evenly throughout day.
