Does adding salt to post-workout water aid rehydration

During exercise or sweating, not only water but also electrolytes like sodium are lost. Adding a small amount of salt to your drinking water helps replenish these lost electrolytes, promoting better water absorption and preventing dehydration.

Purpose: Maintaining fluid homeostasis is crucial, and replenishing electrolytes—particularly sodium (Na+)—is critical for effective rehydration after thermal hypohydration. Despite the growing consumption of carbonated water (CW), its impact ...

If adding even a small amount of salt into your water or sports drink makes you dread even a few sips — let's face it, you can have the most perfectly balanced drink ever developed, but it's not going to help if you don't drink it — there are other ways to get sodium without as much salt, says Harpst. For example, using coconut water can be helpful, since it has both sodium and potassium. That aids with muscle contraction and fluid retention, and you can hide the salty taste by adding a small amount of pineapple juice, Harpst suggests. There are also commercially available electrolyte powders designed to be mixed with water for rehydration, and not only do these contain sodium, they also tend to be flavored.

Sprinkling a tiny pinch of salt into your water and sipping on it during exercise may help counter sodium that’s lost in sweat during a workout, experts say, especially if you’re a so-called “salty sweater,” if you frequently exercise outside in hot weather, or if you have low blood pressure.

... Recent studies confirm that water alone is less effective for rehydration than drinks containing electrolytes. This is because electrolytes improves the absorption of fluids in your gut.

Research suggests that the hydrating effect of salt water might help support the recovery of aerobic capacity and improve athletic performance. ... Salt has natural antimicrobial properties, which help remove toxins from the body.
