Here is a tip that can help those of you with a competitive edge. Drink more water. Water is one of the most simple and cost effective ways to increase performance on the job, on the athletic field or in the classroom. Most people know that our bodies are made up of 60% water and that we need an average of 8 glasses per day to maintain hydration. Do you think you drink 8 glasses per day? Most people think they drink enough, but don’t. One researcher found that professional athletes forced to drink more water than they thought they needed increased their athletic performance by 5 to 10%. How is that for advancing your competitive edge? Another researcher discovered students in a classroom were more alert and attentive and retained more information when they were better hydrated. So, optimize your performance and your health with a simple and cost effective method. Drink more water.
