Water is essential for every bodily function—from regulating temperature to lubricating joints and supporting digestion. Staying hydrated helps maintain energy and cognition.
General guidelines suggest about 8 cups (64 ounces) daily, but needs vary based on body size, activity, climate, and health status.
Tips: drink water regularly throughout the day, eat water-rich fruits and veggies like watermelon and cucumber, and carry a reusable water bottle as a reminder.
