Count water from food and drinks, and sip through the day
Added
Your daily water target includes fluids from food, soup, milk, coffee and tea, not just plain water. Drink when you feel thirsty and have a beverage with meals, choosing water over sweetened drinks. Thirst can change as you get older, so keep taking fluids throughout the day, and ask your doctor if you're unsure you're getting enough.
