How much water does an average person need each day to survive?

An average person needs about 2 to 3 liters (or roughly 8 to 12 cups) of water per day to maintain proper hydration and support bodily functions. However, individual needs can vary based on factors such as age, sex, activity level, and climate. It's important to listen to your body and drink water when you're thirsty, as well as to consider hydration from food and other beverages.
