how much water to drink per day, according to science

Drinking water is not only healthy, it is essential. The human body needs to maintain adequate hydration levels to function properly, and the average person can survive a maximum of three to five days without replacing fluids. But after all, how much water do you really need?

We are sorry to inform you, but no one can give an exact figure. The famous recommendation that you should drink two liters of water per day is nothing more than a myth with no scientific basis.

Yet the myth persists. It is easily repeated in vague health messages, often disseminated by people or institutions unrelated to scientific evidence – who simply echo, echoing, the same mantra they have heard or read elsewhere.

If water is healthy and essential, what would be the problem in recommending at least two liters per day? For starters, this idea is usually used to sell products or distract from really relevant topics.

Companies and organizations that appear to care about our health actually seem outdated – with no interest in updating themselves or disseminating information based on factual knowledge.
