The human body is about 60% water with every single cell and process being dependent on water.  I’m sure all too often you would rather reach for that juice drink, soda, or even cocktail to quench your thirst but you could be sabotaging your productivity.  You see, when your body is dehydrated it will slow itself down to compensate; just a 1% decrease in body fluid weight will reduce exercise performance.  Your body will make you feel tired and sluggish overall, which will obviously make you less likely to exercise and work on your health.  That same 1% reduction in fluids forces your heart to beat an extra 5 beats per minute, and your entire body will be forced to compensate.  Side effects of dehydration range from depression and lethargy to confusion and dulling of your senses.  The idea is not to avoid your favorite drinks but to make sure you add some much needed water to your day so that you can enjoy the day at your best.  Eight glasses of eight ounces is what you hear fairly often but don’t be shy to get in more, that’s just a minimum.  Drink up and your body, work, and all those friends who call you a grump will thank you a million fold.
