Answer 1

Homeostasis bro. You are a bag of liquids that needs to be the right mix of chemicals. When your body does work it excretes water and salt, it needs you to put back in the same mix of water and salt (Gatorade). If instead you put in seawater that is wayyyy to much salt. Your body then uses a lot of water to dilute the salt, now your body is in dire need of water, no more salt.

This is also the reason babies can’t drink water. Babies are teeny tiny bags of chemicals; it’s too easy to dilute the baby.
