Does our body really need 2 liters of water a day?
We’re told this over and over again, but there’s no more truth to this number than to the “10,000 steps” rule.
There is no universal water intake norm. Everyone’s fluid needs are different and depend on many factors:
▫️ body weight and physical activity level
▫️ weather and air humidity (air conditioning dries out the air and increases your need for water!)
▫️ diet and supplements you take
▫️ medications and overall health
That’s why, instead of chasing a number, I advise my patients to listen to their bodies. Here’s what to pay attention to:
✔️ How often do you go to the bathroom?
✔️ What color is your urine?
✔️ Are your lips and skin dry?
✔️ Do you constantly feel thirsty?
For example, I drink 2–3 liters a day, because I exercise, take supplements, and spend all day in an air-conditioned environment. Not because I “have to,” but because my body needs it.
The goal is not to check water off a to-do list, but to give your body exactly as much as it requires.
