All study participants were given deuterium-enriched water. The time of complete removal from the body indicated the water turnover rate.
It turns out that the norm for men is from 1.6 to 1.8 liters per day, for women – from 1.3 to 1.4 liters. The required volume for the elderly is about 1.1 liters per day.
At the same time, people living in hot and humid conditions, athletes, pregnant and breastfeeding women need more water.
The scientists point out that their results contradict the common stereotype of the need for 8 glasses or 2 liters per day. In fact, less – from 1.3 to 1.8 liters, since the liquid enters the body not only directly when drinking, but also from food.
“Science has never supported the old idea of eight glasses as an appropriate guide, simply because the water from drinks mixes up your total water turnover and more of your water from the food you eat,” the researchers said. broadcasting. .
