Sauna Electrolyte Prehydration
Sauna electrolyte prehydration replaces sodium-rich fluids before heat rounds to support sweat losses and reduce dilution headaches.
Sauna electrolyte prehydration means drinking fluids with sodium—and potassium when sweat is heavy—before and between heat rounds so plasma volume stays supported. Plain water alone can dilute sodium during long sweat blocks.
A pinch of salt in water or an electrolyte mix with known sodium per serving beats guessing after dizziness. Avoid alcohol before sauna.

How much sodium before sauna?
There is no universal gram target—hydrate to pale straw urine and include sodium if sessions exceed twenty minutes or you sweat heavily. Clinicians guide medical salt restrictions.
