Runners have long known the importance of replenishing fluids, but they may not know that it is also vital to maintain a balance in sodium levels to keep cells healthy. If runners drink too much fluid, they can dangerously dilute their blood sodium levels. The key, as it is in just about everything is moderation. Yeah, the fluids including the 8-10 glasses (or more) of water are important. But we've got the mindset that all salt is a bad thing. It's not. It's necessary. We've also got the mindset that all fat is a bad thing. It's not.
bump for your post @ 11.
My mom used to quote this constantly to us whelps: "Moderation in all things." As with many other of the things she said, I didn't really grasp the depth of the wisdom till adulthood.
