There isn’t a single clinical trial that has established exactly how much water we need each day to stay healthy, so where did the “8 glasses of water per day” recommendation come from? A recommendation published in 1945 suggested consuming approximately 2.5 liters of water per day, but it also noted that most of this intake would come from food. The average person gets close to 1 liter of water from food daily, and the body also produces metabolic water. Over time, “8 glasses a day” turned into drinking even when you’re not thirsty, but thirst tells the body when to drink fluid. A person’s daily water needs depend on age, body size, physical activity, climate, and other factors, so the number will vary from person to person. Urine color can help indicate your hydration level. Dark urine means you need more water, while clear urine may indicate overhydration, which can negatively affect electrolyte balance. Hyponatremia, low sodium in the blood, is a potential risk of overhydration. Dr. Eric Berg DC Bio: Dr. Berg, age 61, is a chiropractor who specializes in Healthy Ketosis & Intermittent Fasting.

It makes sense to follow your body’s cues: eat when truly hungry, drink when thirsty, sleep when tired, answer nature’s calls.

I used to work with an endocrinologist and he would roll his eyes when a patient would ask if they need to drink 8 glasses of water. He would remind his staff that drink only if you’re thirsty as your body would tell you. Same goes with hunger; to eat only when you’re hungry.
