Drinking water is essential, as “approximately 60 percent of the human body is made up of water.” It supports digestion, nutrient transport, and body temperature regulation. While many believe drinking water first thing in the morning rehydrates the body, this isn’t entirely true, as hydration depends on overall intake throughout the day.

The idea that urine color indicates hydration is misleading, as studies show it’s not always accurate. Claims that morning water intake boosts mental performance or skin health lack scientific proof. Hydration benefits the body regardless of timing.

Regarding weight loss, water can promote fullness and reduce calorie intake. Some studies suggest it may slightly boost metabolism, but timing has little effect. Drinking water before meals may even interfere with digestion.

The “8×8” rule—eight 8-ounce glasses daily—is a general guideline, but water needs vary by individual. The key is staying consistently hydrated.
