      3 days with only water can still “dehydrate” you but in the sense of electrolyte imbalance, which often feels similar to dehydration.

        This is an important thing to note.

        It’s easy to avoid though. Simply put a few grains of salt into your water.

        In the army, as a supply-core nco, that was a must, especially in the summer. A spoon of salt for every jug. I’m gonna refrain from putting the ratios here, because I don’t want anyone to go necking salt because of me. Normally we get enough salt from food, so I’m afraid of some trendy would-be healthy kids starting to add a bunch of salt into their water bottles even when they don’t do any sweating, thinking it’s healthy for them.

        Hyponatremia ends up killing marathon runners pretty commonly, more often than heart attacks but to be fair I wouldn’t expect marathon runners to have a lot of the associated risk factors.
