One thing you hear a lot is that the key to staying hydrated is drinking eight glasses of water a day (or some say a gallon a day). While this is a good rule of thumb, the easiest way to know how much to drink is to simply obey your thirst. Drink when your body tells you it’s thirsty! Don’t wait. By the time you feel really dry, you've already lost 1 to 2 percent of your body’s water.
There are a few ways you can judge whether you’re hydrated enough. For one thing, if your urine is clear or pale yellow, you’re set. You can also measure it by drinking as much water as it takes to keep your lips and mouth moist throughout the day.
If you’re tired, you may be dehydrated. One hidden cause of fatigue is mild dehydration. Just a little deficit can make you feel drained. If you’re feeling somewhat low on energy, a glass of water (instead of a candy bar) may be the jolt you actually need.
Also, remember to sip - not gulp - to get what your body craves. In one study from the University of Toronto, people who downed a glass of water in 15 minutes quickly eliminated most of it the next time they hit the restroom. But those who slowly sipped held on to much more.
In addition to drinking, you can munch, crunch and spoon up water-rich foods. Instead of just drinking water, think about how you can fit fruit, veggies and dairy products into your diet, too. Most healthy foods are also a great source of additional fluids and provide about 20 percent of your daily water needs.

Lastly, many of the effects of aging are due to dehydration. The advice to eat water rich foods is something you shouldn't ignore. Honestly, they should be most of what you eat. Of course, at least once a day, you can enjoy a water-rich meal replacement shake - like Shakeology.
Just remember: in your daily habits, in your food choices and in your lifestyle overall, always think of hydration.
