What do electrolytes and sodium have to do with hydration? Is water alone not enough?

Ever since I started running, all I know is that I need to drink a sh*t ton of electrolytes. But I would like to understand why on a physiological level.

Electricity doesn’t like pure water. Without free ions that are able to move easily the bodies microvolt impulses to do things like tell your heart to pump or your lungs to breath don’t work so well.
Also you constantly use up electrolytes through sweating and peeing so your body needs to replace that.
