Yes: Sodium is colorless, so cannot use color to gauge loss/retention in urine--only overall hydration level. If only drinking water, and lots of it, particularly if sweating heavily, can become hyponatremic. Alternate water with electrolyte drink or drink 1/2 strength when active. Avoid salt tablets--they do more harm than good in most users.
