Water
Fluid
fluctuations affect blood volume and intracellular hydration levels.
This can be life threatening. When the amount of fluid within various
cellular compartments is relatively constant, there is an exchange of
solutes and water between compartments to maintain unique compositions.
Individuals with more body fat have proportionately less total body
water and are more susceptible to fluid imbalances that cause dehydration.
Total body water percentage decreases with age,
resulting in inadequate cellular hydration. Most critical is the decrease
in the ratio of intracellular hydration. The normal ratio is 60% intracellular,
40% extracellular. The reason for change in this ratio is due in part
to an increase in fat along with a decrease in muscle, and a decreased
ability of the body to regulate sodium and water balance. With age,
kidney function becomes less efficient in producing urine, and responses
for conserving sodium weaken.
The
body must continuously be in a proper state of hydration. Because 2.5
liters of water is lost each day through normal bodily functions, this
must be replaced. There are two major issues that emphasize the need
to keep the body adequately hydrated with water of the best quality,
content, and structure so it can maintain homeostasis. First, the water
we put in our body must be able to prevent toxins and chemical substances
from accumulating and creating destructive influences on cells. Water
must bring all minerals and nutrients required for cell metabolism,
and remove any substances that can damage the cell. It must also be
able to protect cell walls from damage and invasion. Second, since water
is involved in every function of the body, it must act as a conductor
of electrochemical activity, such as neurotransmission, by moving water
from one nerve cell to another smoothly and effectively.
Movement
of water in the body between cells (extracellular fluid) is caused by
osmosis. This is created by magnetic forces in the body, which keep
the movement in balance. As water flows, changes in pressure create
movement across the cell membranes. Any changes in pressure will allow
proteins, minerals and other nutrients being carried by the blood to
escape into spaces between vessels and deprive the cells of their vital
needs to sustain life. When water in the blood is contaminated with
chemicals, it enters the cells and changes their structure, which in
turn could lead to changes in DNA (pleomorphism). This is the start
of the disease process, which is very similar to the aging process.
