The "8×8 rule" suggests drinking eight 8-ounce glasses of water daily, but this isn’t a definitive guideline for everyone. Individual water needs vary based on factors like age, sex, and activity level. On average, women need about 11 cups (2.7 liters) of water daily, while men need about 15 cups (3.7 liters) to stay hydrated. Remember that around 20% of your daily water intake comes from food.

Water is vital for maintaining overall health. It makes up approximately 60% of your body weight and plays a crucial role in various bodily functions. The brain, with an even higher water concentration of 73%, relies on adequate hydration for consistent activity. Proper hydration also helps boost energy levels, reduce the risk of heart failure, and lubricate joints.
