The recommended daily water intake for adults is about 2-3 liters. This guideline is based on the needs of the average adult for maintaining proper hydration, which is essential for numerous bodily functions, including maintaining body temperature, lubricating joints, and transporting nutrients. The amount can vary based on factors such as age, gender, climate, and physical activity levels, but the general consensus is that 2-3 liters is sufficient for most adults to support their health and normal physiological functions.
