1 Determine how much water you need. You've probably heard the "8 by 8" rule - drink eight 8-ounce glasses of water per day (2 qts, 1.8 l) - but the amount of water a person needs varies depending on his or her weight and activity level. Another way to determine your specific recommended water intake is to divide your weight (in pounds) by two. The resulting number is the number of ounces of water you need each day. For example, if you weigh 150 lbs., strive to drink 75 ounces of water daily. For those who use the Metric system, divide your weight (in kilograms) by 30 (ex. somebody weighing 70 kg is going to need 2.3 litres per day). Keep in mind that these recommended intake numbers are controversial and some experts believe they are a gross exaggeration. See "warnings" below for more information.
2 Measure your daily intake of water. Do this for a few days. If you find that you're drinking less than the recommended quantity, try some of the following tips.
3 Carry water with you everywhere you go in a bottle or other container. Before long, you'll find yourself reaching for it without a second thought.
4 Keep a glass or cup of water next to you whenever you'll be sitting down for a long time, such as when you're at your desk at work. Drink from it regularly as you're working.
5 Try wearing a digital watch that beeps at the beginning of each hour. Use that as a reminder to pour yourself a glass of water. Vow to drink that water before the next beep. If you drink only one small (6 ounce or 180 ml) cup per hour, you'll have consumed 48 ounces (1.4 l) by the end of an 8-hour workday.
6 Get a water purification system. Purified water tastes very good and may help make drinking water more appealing to you. Be aware, though, that as you grow accustomed to purified water, you may find that tap water leaves a bad taste in your mouth.
