Answer 1

The body needs sodium/salt. If it dips too low, your cells stop functioning. (My dad almost died from sodium deficiency, so I’m painfully aware of this.) So, don’t make the assumption that salt = bad. It’s the exact opposite. Salt, along with other electrolytes, is absolutely necessary for human survival. It’s just that salt water has way too much of it and saline has the perfect amount.
