Being healthy is not just about eating well and going to gym. To me the most important health tip I can give is staying hydrated. You should always have a bottle of water with you at all times. Thus creating a reminder that you body NEEDS it. Without water your body cannot function at a normal a pace. Our bodies are mostly made up of water. So when we "go dry" in a sense that is not good. 

If you are like me and you just cannot drink out of the water bottle that the water comes in then I have a solution for you! Just got purchase your own bottle. I suggest CamelBaks, or Nalgene. I use a Nalgene because they hole more water! So always remember to stay hydrated!
