Dehydration — Signs and Solutions
Overview
Dehydration occurs when the body loses more fluids than it takes in, affecting physical performance, cognitive function, and overall health. Workers in hot environments, those wearing protective equipment, or performing physical labor face increased dehydration risks that can lead to serious health consequences.
Why This Is Important
Even mild dehydration can reduce physical performance by 10-15% and impair concentration, increasing accident risk. Severe dehydration contributes to heat-related illnesses and can cause kidney damage, seizures, and life-threatening complications.
Dehydration develops gradually and often goes unnoticed until symptoms become severe. By the time you feel thirsty, you’re already experiencing fluid loss that affects your body’s ability to regulate temperature and maintain normal functions.
Best Practices & Safety Tips
Drink Before You're Thirsty
Consume 6-8 ounces of water every 15-20 minutes during work. Don't wait until you feel thirsty - it's too late by then.
Start Hydrated
Drink 16-20 ounces of water 2-3 hours before work begins. Monitor urine color as a hydration indicator.
Replace Electrolytes
Use sports drinks during prolonged sweating to replace sodium and other minerals lost through perspiration.
Choose Cool Fluids
Cold beverages are absorbed faster and help lower body temperature. Keep water easily accessible and at cool temperatures.
Dehydration Warning Signs
Early Signs
Thirst, dry mouth, decreased urine output, dark yellow urine, fatigue, and mild headache indicate beginning dehydration.
Moderate Dehydration
Dizziness, rapid heartbeat, muscle cramps, nausea, and significantly reduced urine production require immediate attention.
Severe Dehydration
Confusion, lethargy, unconsciousness, and absence of sweating are medical emergencies requiring immediate professional care.
Factors Affecting Hydration Needs
- Physical Work Intensity - Work intensity and duration determine fluid replacement requirements
- Individual Factors - Age, medications, health conditions, and fitness level affect hydration needs
- Protective Equipment - PPE and protective clothing can trap heat and increase sweating
- Environmental Conditions - Temperature, humidity, and wind affect sweat rates and fluid loss
Hydration Monitoring
- Urine Color Test - Pale yellow indicates good hydration; dark yellow suggests dehydration
- Weight Monitoring - Check body weight before and after work; 2% loss indicates significant dehydration
- Thirst Response - If you’re thirsty, you’re already dehydrated
- Performance Indicators - Decreased coordination, concentration, or energy may signal dehydration

Takeaway: Proper hydration is essential for safety, health, and job performance. Make drinking water a regular habit throughout your workday, not something you do only when thirsty. Monitor your hydration status and adjust fluid intake based on work conditions and individual needs - your body and your safety depend on it.
