Contributing to this change in the proportion of body water
is a combination of increasingly sedentary lifestyles, blunting of thirst mechanisms, reduced ability of the kidneys to concentrate urine and less efficient hormonal regulation of water loss (see Box 1, p23).
Without physiological regulation of proper body water
levels, too much water would result in an insect's cells swelling and rupturing, while excessive water lost results in precipitation of soluble metabolites, causing irreversible harm (Hadley 1994).
"Seniors can become dangerously dry because their body water
content decreases and medications can dehydrate them.
RESULTS: Old females had significantly more fat, greater truncal skinfolds and circumferences, and significantly less fat-free body mass (FFM), total body potassium (TBK), total body water
(TBW), and bone mineral than did their young matched counterparts.
A mere 2% drop in body water
can trigger fuzzy short-term memory, trouble with basic math, and difficulty focusing on the computer screen or on a printed page.
They discuss water flux and amniotic fluid volume in the fetus, body water
changes in the fetus and newborn, electrolyte balance during normal development, normal development of the kidney, and special problems such as fetal origins of adult cardiovascular disease, renal modulation, acute problems of prematurity, lung fluid balance, edema, kidney injury, and obstructive uropathy.
Obesity can reduce someone's total body water
from a healthful 65% to 35%.
The principle of the method is based on distinctive electrical properties of tissues, fat and body water
. Fat-free matter containing a large proportion of water and electrolytes is a good conductor, unlike the fat tissue, behaving like an insulator .
The latter is reflected in a decrease in body weight and changes in hematological  and biochemical  parameters of body water
