Is it true that you need to drink eight glasses of water a day?
For years, We have heard the recommendation to drink eight glasses of water a day to stay healthy. This suggestion has been repeated so often that many people follow it to the letter, as if it were an unbreakable medical rule. But how true is this statement? Do we all really need exactly that amount of water daily? Science has something to say about that.

Where does the "8-cup" rule come from?The famous recommendation comes, in part, from a 1945 publication by the U.S. Food and Nutrition Board, which suggested that an adult should consume approximately 2.5 liters of water per day. However, what many people overlooked was that the same report mentioned that much of that fluid could come from food and other beverages, not just plain water. Over time, the message was simplified and shifted to the slogan "drink eight glasses of water a day," without further context.
The amount of water a person needs varies depending on various factors such as age, weight, level of physical activity, climate, health status and even diet. For example, someone who exercises regularly or lives in a hot climate will require more fluids than someone who is sedentary in a temperate environment.
Additionally, many foods we consume daily contain water: fruits like watermelon and oranges, vegetables like cucumber and lettuce, and even soups or stews provide a significant amount of hydration.
What do the experts say today?According to the Mayo Clinic and other reliable medical sources, a good way to know if you're well hydrated is to pay attention to signs like thirst and urine color. If you rarely feel thirsty and your urine is clear or pale yellow, you're probably getting the right amount of fluids.
There's no magic number that applies to everyone. Instead of blindly following the eight-glass rule, it's best to listen to your body and maintain consistent hydration throughout the day, especially if you're exposed to the sun, exercising, or eating very salty foods.
Can drinking too much water be harmful?Yes, although rare, excessive water consumption in a short period of time can lead to a condition called hyponatremia, which occurs when the sodium level in the blood drops too low, which can be dangerous to your health. This most commonly occurs in athletes who overhydrate without replacing electrolytes, or in people who They drink large amounts of water unnecessarily.
Drinking water is essential for keeping your body functioning properly, but you don't need to obsess over achieving exactly eight glasses a day. Your body is the best indicator: if you're thirsty, drink; if your urine is very dark, you probably need to hydrate more. The key is balance and maintaining a routine that fits your personal needs, not a general formula.
