Increasing salt intake makes me feel better. Why?

It’s often said that we shouldn’t eat too much salt, that we should reduce sodium intake, so on so forth.

But, I’ve found that I feel much better, both mind and body, if I go beyond the ~2 grams that’s recommended a day. And days when I get less, I find that I crave salty foods more than anything.

So, why is this the case, when everyone seems to think salt is bad (beyond a baseline of electrolytes)
