Hi, I'm Mike Kaviston. I'm the Director of Fitness at the Naval Special Warfare Center, and welcome to another training video podcast. I want to talk for a couple of minutes about the importance of hydration. Physical training, lots of effort, and you're going to be pouring out lots of sweat, even in an environment like Coronado where the temperature is rarely extremely high, and the community's not that much. With all the physical exertions, students lose lots and lots of fluid, and so they need to replace it constantly. And so my major recommendation is to not only be smart and have water available while you're training, and replace fluids when you're done exercising, but make sure to be hydrated before you even start. In other words, hydration has to be something that you pursue aggressively all day long from the time you get up until you go to bed. And so regularly drink fluids, mostly water, juices, sports drinks, maybe occasionally. I dilute them a little bit first, but primary thing that I want to convey is the importance of getting liquids into your body on a regular basis. How do you know if you're hydrated enough? Well, a couple of things that you can do is pay attention to your urine output. You should be peeing a lot, basically, and the urine should be relatively clear. Another major thing that can tip you off into how well you're hydrated is when you go to sleep at night, you should wake up during the night to use the bathroom. Or if you don't, when you get up, you should definitely have to go right away. If you can sleep through the night and get up without having to use the bathroom, then you're probably not hydrated enough. So just something to think about, and a habit that you want to get into before you show up here at Buds is make sure that you're used to hydrating on a regular basis. This has been another training video podcast.
