Higher blood pressure. The blood in a dehydrated body
thickens and moves more slowly, so blood pressure increases to
move the blood through the body.
Higher cholesterol. Dehydration also can lead to higher
blood cholesterol, which is the body’s way of preventing water
loss at the cellular level. As the body loses more water, it produces more cholesterol.
ALLERGIES AND ASTHMA
A dehydrated body also restricts airways to conserve water.
In addition, the rate of histamine production increases
exponentially as water loss continues. When the body produces
too much histamine, allergic reactions present. High levels of
histamine in the nasal passages cause nasal congestion, runny
nose and excessive sneezing. Histamine also affects the eyes,
throat, skin and airways.
Digestive disorders including ulcers, gastritis and acid re;ux
can present in a human body that is deprived of water and
alkaline minerals such as calcium and magnesium.
As the amount of water in a human body decreases, the
body reduces water supplies to parts of the body that are not
critical to survival. One of the parts affected is the colon. When
this water rationing occurs, the large intestine is hampered in
performing food processing and waste extraction. This can lead
to constipation and dif;cult waste elimination.
Other digestive side effects of dehydration include weight
gain, skin disorders, toxic byproducts stored in fat cells, joint
discomfort and stiffness, liver issues and kidney problems.
Dehydration is largely preventable with a few, easy steps.
• Drink a cool glass of water ;rst thing each morning.
• Continue drinking water throughout the day. The amount
of water required varies depending on a person’s physiology,
diet and activity level. Determine the appropriate amount,
and stick with it. Somewhere between 8 and 24 ounces an
hour is typical.
• Recognize dehydration symptoms:
In hot weather, body temperature rises.
As a result, sweat rate increases as the body attempts to
Sweating leads to ;uid and electrolyte loss, which can
lead to dehydration, heat-related illnesses or both. Those
• Nausea, vomiting or both.
