Dehydration
Self-care
Drink more fluid to prevent dehydration. Adults generally need 2 litres of water a day, more in warm weather or with exertion. Check urine colour daily; pale yellow is healthy.
Do this
• Drink at least 1.5 to 2 litres of water a day
• Eat foods with a high water content such as fruit and soup
• Avoid excessive caffeine and alcohol
• Drink more in warm weather or with physical exertion
• Use urine colour as an indicator of hydration
Warning signs
• Dark or brown urine
• Headache and dizziness
• Dry lips or mouth
• Little or no urine passed
