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.

When you’re exercising you’re sweating. In addition to water, sweat has a lot of electrolytes in it. That is why sweat is salty.

Water is the most important thing you need when hydrating, but you benefit more if you can replenish your electrolytes as well.
