intra cellular volume? addition of only water--> hypoosmolality of ECF--> water moves into the cell.

Default my answer

I agree with vna.rao22 - intracellular volume

he was sweating so he was loosing hypotonic fluid -> became slightly hipertonic -> drank a lot of hypotonic fluid -> became hypotonic in ECF -> water moved to ICF (brain cells swell->confusion).

That's why they created isotonic fluids
