How much water drains out of you when you drink no water?

The amount of water that drains out of the body without water intake varies based on several factors, including activity level, climate, and individual metabolism. On average, an adult can lose about 2 to 3 liters of water per day through urine, sweat, and respiration. Without drinking water, the body will gradually dehydrate, leading to a decrease in performance and health issues. It's essential to maintain hydration for optimal bodily functions.
