about a liter and a half in urine,

排出水的方式有很多尿大约含一升半
almost a third of a liter through your lungs

通过肺排出的大约有三分之一升
because you breathe in air that's relatively dry,

因为你吸入的空气相对干燥
you breathe out air that's very humid.

而呼出的气体相当湿润
If you take a glass plate and you breathe out on it,

如果你取一块玻璃板哈气在上面
it gets foggy, you could see water condense

上面会起雾你能看到凝结的水
because your breathe is much more--

因为你的呼吸更加
has much more water in it than the air around us,

比周围的空气含有更多的水分
so we lose actually quite a lot of water that way.

因此事实上从该途径会排出相当多的水
Through sweat and other activities you lose more water,

通过出汗和其它运动你损失的水分更多
so that your daily loss balances your daily intake.

因此你的日损失量和日摄入量平衡
Now, what if you drink more water?

假如你喝更多的水的呢
