Drinking the proper amount of water a day is one of the easiest and cheapest ways for people to improve their health, but people regularly drink far less water than they should be. Make sure you get your recommended water every day. Make a point of getting a water bottle with markings to show how many ounces you are drinking. There are some bottles that even indicate how much water you should have drank by different times of day. There are also apps that allow for you to track your water intake.
