Dehydration results when fluid losses exceed fluid intake. Conditions that can lead to dehydration include:
- Not drinking enough fluids daily.
- Working or exercising in a hot environment (wet or dry).
- Working or exercising in a cold environment (wet or dry).
- Going to high altitudes.
- Drinking too much alcohol or exercising with a hangover.
If 4% of your body weight is lost through fluid losses, decision-making, concentration, and physical work are impaired. A loss of 20% of body water can result in death (see Figure 2-1).
