The “Eight Glasses of Water Per Day” Rule is a Myth

The “eight glasses of water per day” rule has plagued the minds of health-conscious individuals ever since the Food and Nutrition Board recommended the standard back in 1945—and apparently, it’s not true. While people do need about 2.5 liters of liquid per day, much of that comes in the form of food, fruits, soft drinks and even coffee, eliminating the need for an additional eight glasses. On top of that, there’s actually no scientific proof that extra water leads to softer, wrinkle-free skin, or that yellow urine means dehydration. So if you aren’t presently thirsty, you’re probably sufficiently hydrated.
