                                While the "8x8 rule" is a common guideline, a more personalized approach for hydration is often recommended, especially since needs vary based on body weight. For someone weighing 100 pounds, a general starting point is to consume around 50 to 67 ounces of water per day, with adjustments necessary for activity level and environment.
