How to form a good water habit?

• How much water?
  This is a debatable question. What's clear is that the old recommendation of "eight 8-ounce glasses a day" isn't right, for several reasons: that amount includes all dietary water intake, including food and non-water beverages; it also ignores a person's body weight, which is an important factor in figuring the amount; it also varies if you are sick or exercise. It's also not good to just drink when you're thirsty -- you're already dehydrated by then. Best is to form a routine: drink a glass when you wake up, a glass with each meal, a glass in between meals, and be sure to drink before, during and after exercise. Try to generally keep yourself from getting thirsty.

• Carry a bottle
    Keep a glass of water and drink from it all day long. When it's empty, fill it up again, and keep drinking.

• Filter
  Instead of spending a fortune on bottled water, invest in a filter for your home faucet. It'll make tap water taste like bottled, at a fraction of the price.

• Exercise
  Exercising can help make you want to drink water more. It's not necessary to drink sports drinks like Gatorade when you exercise, unless you are doing it for more than an hour. Just drink water. If you're going to exercise, be sure to drink water a couple hours ahead of time, so that it will get through your system in time, and again, drink during and after exercise as well.

• Track it
  It often helps, when forming a new habit, to keep track of it -- it increases awareness and helps you ensure that you're staying on track. Keep a little log (it can be done on an index card or a notebook), which can be as simple as a tick mark for each glass of water you drink.
