When the Human Body Does Not Get Enough Water:
- A decrease of as little as 2% in our body's water supply can have harmful effects and cause symptoms of dehydration, such as daytime fatigue, excess thirst, fuzzy memory, difficulty focusing on tasks and simple math, light headedness, and nausea.
- It has been estimated that 75% of Americans have mild, chronic dehydration (excessive daytime fatigue is the major symptom).
- A reduction of 4-5% in body water can result in a 20-30% decrease in work and exercise performance.
- A 10% decrease in water will produce significant health risks.
- A week without water will surely result in death.
