Rest Day Sodium Reduction Myth
The rest day sodium reduction myth over-cuts salt on off days—moderate sodium still supports volume and recovery after heavy sweat.
The rest day sodium reduction myth claims athletes should slash salt to near zero on off days to "detox" or protect blood pressure. In practice, moderate sodium from soups, bread, cheese, and sauces still supports plasma volume and next-day training readiness—especially when yesterday was a heavy sweat day.
Cutting salt and water together can leave you flat, lightheaded, or craving salty takeout by evening. Hypertension plans are different and clinician-led.
Common questions
-
When should sodium actually drop on rest days?
When a clinician sets a medical sodium cap or you are between heat blocks with low sweat and stable blood pressure. Otherwise keep habitual food sodium and adjust drink sodium to tomorrow's session.
