Tips to Stay Hydrated

  • Drink a glass of water first thing when you wake up.
  • Carry a reusable water bottle with you throughout the day.
  • Set reminders on your phone if you tend to forget.
  • Eat water-rich foods like cucumbers, watermelon, and oranges.
  • Drink a glass before each meal to build the habit.
  • If plain water gets boring, add lemon, mint, or cucumber slices.
