Understanding Thirst and Optimal Hydration Practices

Water is critical to human life. Our bodies are more than 50 percent water. We can survive months barely eating, but even a few days without water and we’ll die. Water flushes toxins out of our organs and cools us down after a workout. But how much do really need? And how much is too much? Lately there’s been a lot of attention on the internet to what’s known as the Water Gallon Challenge: drinking a gallon per day for a month, with the promise of glowing skin and a lot more energy. Outside editor Aleta Burchyski took on this challenge, which for her was all the more daunting because she hates the taste of plain tap water. In this episode, we talk to her about her quest and check in with a leading hydration expert, who explains that we don’t know as much about how water effects our bodies as you might think.
