A:水对健康确实至关重要,体内各个系统的正常运转离不开水。人体在新陈代谢的过程中会消耗水分。排尿是排出水分的重要方式,此外,我们每时每刻都在不断地通过呼吸、出汗等过程失去水分。一个人每天失去水分的量因人而异,并且与当时的身体状态、运动情况、环境条件等有关。平均来说,一个体重70千克的成年人,每天排尿约1500毫升,占一天中失水总量的60%左右;通过呼吸和出汗失去的水分约有八九百毫升,占到近40%。如果我们摄入的水分不足以补充失去的水分,就会处于脱水状态。体内水分减少5%以上就会导致疲劳、头晕

Urination is an important way to discharge moisture, in addition, we constantly lose moisture by breathing, sweating and other processes.

On average, a 70-kg-weight adult spews about 1500 milliliters of urine a day, accounting for about 60% of the total amount of water lost in a day; about 8900 milliliters of water lost through breathing and sweating, accounting for nearly 40% . If we do not consume enough water to replenish lost water, we are dehydrated. Body water reduction of more than 5% will lead to fatigue, dizziness
