Water is essential for life, fighting dehydration and helping our bodies flush out toxins and improve bodily functions. For years, researchers and health experts have recommended drinking eight 8-oz glasses (about 2.5 liters) of water everyday to maintain health. While the number isn't exactly a strict prescription [1] , there are certain advantages to drinking more water every day. Some research even suggests that increasing your daily water consumption can actually help you live longer. [2] Finding ways to drink more water can help you feel healthier and more hydrated everyday.

    2 liters (0.5 US gal) is about 8 glasses of water. Having a container that size may help you remember to drink enough water every day.
    • If you have an empty 2-liter soda bottle, fill it with water and put it in your fridge. Drink the entire bottle of water over the course of the day.
    • If you are not drinking the entire bottle of water each day, you may not be getting enough water.

    Did You Know? The amount of water varies based on height, weight, activity levels, and other factors. To accurately know if you're getting enough water, check to see if your urine is clear or a very pale yellow. If it is, then you're hydrating properly!

    Train yourself to drink a glass of water every morning when you first wake up, a glass when you get home from work or school, and a glass every evening right before bed. That's three of your eight recommended daily glasses. You can make a daily water chart to help you get started, and after a while, the practice will feel like second nature.
    • Drinking water in the morning also helps jump-start your metabolism, and is a refreshing way to wake up every day. [3]
    • There are also water bottles on the market with counting systems worked into their design. For instance, some bottles have a little dial that is turned each time 8 oz is drank. This encourages more water consumption.

    Another habit to cultivate is sipping a glass of water while you're doing other work, whether on the computer or watching TV. [4]

    There are many apps available for your smartphone that can help you keep track of how much water you've drunk, or give you reminders to drink more. Many are free, but if you pay for one, you might be more motivated to use it on a daily basis. [5]

    Carry your bottle everywhere you go. Not only will it reduce the number of disposable water bottles you go through, it may also motivate you to use your new bottle.
    • Remember to use a water bottle that not only looks nice, feels nice and keeps your water cold, but also one that is BPA free and easily washable.

    Health professionals will often advise you to drink more water than usual (which can mean more than 8 glasses a day), depending on environmental factors. If you live in a hot, dry climate, you'll probably need to drink more water than someone who lives in an arctic climate. And if you're exercising, you'll need even more water to stay hydrated.
    • Don't wait until you're thirsty to drink water, especially if you're engaging in physical activity and/or if the weather is hot. By the time you feel thirsty, your body is already dehydrated. [6]

    This will make you fuller before you eat, and may even stave off cravings, as thirst is often mistaken for hunger. [7]

    Slicing up citrus, berries, or even cucumbers into your water will give it a zesty, fresh taste that will keep you coming back for more.

    Expert Answer
    8 glasses are equal to 64 ounces, which is a little less than 2 liters of water. So, aim to drink around 2 liters of water per day.

    It depends on your size - if you are a very small/petite person, this may be more than you need. If you are larger, you may need more than this.

    Fluid guidelines are based on how many calories you consume. Generally, 1 milliliter per calorie will give you a daily total.
