The water loss of human body from urine, sweat or skin evaporation every day is about 1800 ~ 2000ml, so healthy adults need to replenish about 2000ml of water every day. But 2000ml of water is not necessarily obtained by drinking water, and the moisture in food should be included.

Each person should consume no less than 2000ml of water every day, and directly drink no less than1500ml of water. Don't wait until you are thirsty to replenish water.

Drink water in small sips, only after three sips, leaving room for digestion and absorption.
