Eli5: Why do electrolytes hydrate you but saltwater dehydrates you?
In: 9
It’s not strictly speaking accurate to say electrolytes hydrate you. When you sweat you lose both water and salt. Simply replacing that with water will result in your body not having enough salt which is unhealthy. Sports drinks just add electrolytes (salt) to replenish what you lost from sweat. Also usuaadd sugar since you’re burning that too when you exercise.
