Frequently asked questions
- How much water should I drink per day?
- A common rule of thumb is 35 mL per kilogram of body weight, plus extra for exercise. A 70 kg person doing 30 minutes of exercise should aim for about 2.8 litres per day.
- Does coffee count toward daily water intake?
- Caffeinated drinks have a mild diuretic effect but still contribute to hydration. Plain water is best; other fluids count partially.
