When does dehydration occur?
- At just 1-2% dehydration, or when you’ve lost 1-2% of your body’s water, mental performance and physical coordination start to become impaired — and you’re not even thirsty yet
- At 2-4% dehydration, you’ll feel thirsty and possibly some of these other symptoms:
- Fatigue, lethargy, fuzzy thinking
- Irritability
- Dizziness
- Headache
- Dry mouth and skin
- Muscle cramps
- Rapid pulse (100 beats/minute or higher)
- Fever and chills
