In fact, you may have one sitting next to you right now (and if you do, congrats). We’re talking about reusable water bottles. These may seem relatively unimportant at first glance, but the fact of the matter is that most adults are chronically dehydrated because they rarely have water within reach.

Instead, we drink soda, coffee and other caffeinated beverages. These deplete the body of much needed H20 and, unfortunately, comprise most of the average adult’s fluid intake. Fortunately, studies show that people who keep a refillable water container with them during the day are most likely to drink plenty of water.

You can easily become one of these bottle-toting people. Invest a few bucks in a sturdy water bottle that’s dishwasher safe and let chronic dehydration become a thing of the past. With proper hydration, you’ll notice a marked improvement in your overall energy levels and athletic performance, as well as in the condition of your skin.
