Your energy level and your water level are linked. If your body becomes dehydrated, this will zap you of energy and can cause you to feel dizzy, lightheaded, confused, and it can impair your ability to focus on the tasks at hand.

Never wait until you feel thirsty to drink water; keep yourself hydrated by consuming at least six to eight glasses a day. If you go to the gym before you head to work or if you walk during your lunch hour, then drink water before you begin to exercise and keep yourself well hydrated during and following your workout.
