Frequently Asked Questions
How much extra water do I need in hot weather?
▼
Increase intake 50-100% above normal. If you normally need 2.5L, drink 4-5L in hot weather. More if you're active or sweating heavily.
What are signs of heat dehydration?
▼
Early: thirst, dark urine, headache, fatigue. Severe: dizziness, rapid heartbeat, confusion, no sweating despite heat. Seek medical help for severe symptoms.
Should I drink sports drinks in hot weather?
▼
For activity over 60 minutes or heavy sweating, yes. Electrolytes (especially sodium) lost in sweat need replacing. Plain water alone can dilute electrolytes dangerously.
Can I drink too cold water in heat?
▼
Cold water is fine and may be more palatable, encouraging you to drink more. Stomach cramps are rare and water temperature doesn't significantly affect hydration.
How do I stay hydrated working outdoors in heat?
▼
Pre-hydrate before starting. Drink 250ml every 15-20 minutes during work. Take shade breaks. Monitor urine color. Use electrolytes if sweating heavily for hours.
