EuhydrationEuhydration

“Normal” body water levels

Males – 55-60%

Females – 50-55%

Maintained relatively well due to thirst and hunger (for people who can satisfy each)

Impossible to set general requirements for hydration

EuhydrationEuhydration

Properly regulates body temperature

Sustains proper cardiovascular function

Maintains effective nutrient delivery

Cell homeostasis

Proper blood viscosity and plasma levels

Overhydration (hyperhydration)Overhydration (hyperhydration)

Body contains too much water – water intoxication

Cannot excrete water – normal sodium level diluted [hyponatrimia]

Rarely occurs from water consumption alone

With normal heart, kidney, and pituitary gland function, individual would need to consume an excess of two gallons of water a day.

Symptoms of OverhydrationSymptoms of Overhydration

The brain is most susceptible to overhydration Change in behavior

Confused

Drowsy

Inattentive

Nausea/vomiting

Acidosis – abnormally high acid content in bloodand body tissue

Risk Factors for OverhydrationRisk Factors for Overhydration

Most common with individuals with impaired kidney function

Infants at greater risk due to lack of kidney development

Often occurs in healthcare field when provider administers more fluids than body can handle due to condition.

Coma

Kidney failure

Heart disease

Uncontrolled diabetes

Prevent OverhydrationPrevent Overhydration

Take weight after bouts of intense physical activity to replenish proper amounts of fluid.

1 lb lost – replenish with 15 oz. water

Avoid drinking more than 1 liter of water per hour

Be aware of medical conditions and treatments

DehydrationDehydration

Loss of body fluids (mainly water) exceeds amount taken in.

Lose water in a variety of ways

Potty breaks

Sweat – includes body water and electrolytes

Breathing

Rate at which we lose water varies from person to person

Risk Factors for DehydrationRisk Factors for Dehydration

Chronic or acute illness/disease

Consumption of diuretics

Bouts of exercise

Heat exposure

Poor diet

Prevent DehydrationPrevent Dehydration



Hydrate properly prior to exercise

Combination of water and electrolyte rich drinks

Avoid exercise in high heat

Replenish fluids during and after exercise

Monitor urine color – pale yellow to clear = euhydrationdark yellow = dehydration
