Health guidelines recommend drinking at least 1.5 liters of water daily for optimal hydration. But how do you confirm you've met this goal?
Without a built-in tracker, it's easy to lose count. Try this proven, straightforward method: Mark two bottles with your drinking times throughout the day.

1. Grab two reusable bottles.
2. Label them with key times to drink, like morning, midday, and evening.
3. Fill them up and sip on schedule.

At day's end, empty bottles confirm your intake. It's reliable for adults and a great way to encourage kids to stay hydrated.
