Quick answer
Sodium depletion through sweat can contribute to muscle cramps during exercise. Electrolyte replacement including salt helps prevent exercise-related cramping for some athletes.

How Sodium Loss Relates to Cramps
Sodium depletion through sweat can contribute to muscle cramps during exercise. Electrolyte replacement including salt helps prevent exercise-related cramping. Cramps also stem from fatigue, dehydration, and individual factors. Salt alone does not fix every cramp.
Replacing Salt During Exercise
Athletes who sweat heavily for more than 60 to 90 minutes may benefit from sports drinks or salty snacks. Typical sweat contains 500 to 1,500 mg sodium per liter. Drink fluids with electrolytes during long hot sessions. Plain water alone can dilute blood sodium if you sweat heavily without replacement.
Daily Sodium Balance
The WHO recommends limiting sodium to under 2 g per day (about 5 g salt) for the general population. Active people may need more on training days. Do not add large salt loads without guidance if you have heart or kidney conditions. Consult a clinician for a plan that fits your health status.
Other Cramp Prevention Tips
Warm up properly, stretch after exercise, and stay hydrated. Magnesium and potassium from food also support muscle function. Persistent or severe cramps warrant a medical evaluation to rule out underlying conditions.
