Your kidneys filter out excess waste and water

But they can only process 800 to 1,000 milliliters

of water an hour, and if you somehow managed

to drink more than that without throwing up,

Normally, your cells are surrounded by a carefully balanced

solution of sodium and water, which flows in and out

through tiny holes in the cellular membrane.

So it keeps the sodium concentration, both in and out

So some of that excess water rushes into the cell

Now, most of your cells can handle the swelling to a degree,

since soft, flexible tissue like fat and muscle can stretch.

But for the cells in your brain, it's another story,

So, as your brain swells it builds up pressure in your head.

and is more likely to happen in people who have

kidney issues, since they can't process water

The average healthy adult needs somewhere around

and other drinks too, drink when you're thirsty,
