In this episode of the NPR Life Kit podcast, common myths about hydration are put to rest. Experts suggest that for most people, listening to your thirst is the best way to determine how much water you need, challenging the old "eight glasses a day" guideline. They warn that drinking too much water can be harmful, leading to a condition called hyponatremia, but our bodies are generally good at managing the balance of water and sodium. Interestingly, urine color isn't a reliable sign of hydration compared to thirst, and caffeine doesn't actually dehydrate you. For those engaging in intense physical activity, getting electrolytes is important, but you can find them in many foods and drinks, not just sports beverages.
