Hydration Tips
- Drink a glass of water first thing in the morning to kick-start metabolism.
- Drink 500ml (17 oz) 30 minutes before meals to aid digestion.
- Urine color is the easiest indicator — pale yellow means well hydrated.
- Coffee and tea count toward fluid intake, but limit to 3–4 cups per day.
- Thirst is a late signal — drink regularly before feeling thirsty.
- Hot climates and exercise can increase water needs by 500ml–1L or more.
