This simple lesson was taught to us day one in boot camp when I was in the army, and reiterated constantly over the years.
We were required to take our salt packet out of our MRE's and eat the entire contents. The amount of water consumed (and flushed out through perspiration) throughout the day would have severely dehydrated anyone who didn't consume adequate (high) levels of salt.
