Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries, the water supplied to households, commerce and industry meets drinking water standards, even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing, washing and landscape irrigation.

Over large parts of the world, humans have inadequate access to potable water and use sources contaminated with disease vectors, pathogens or unacceptable levels of toxins or suspended solids. Drinking or using such water in food preparation leads to widespread acute and chronic illnesses and is a major cause of death and misery in many countries. Reduction of waterborne diseases is a major public health goal in developing countries.

Water has always been an important and life-sustaining drink to humans and is essential to the survival of all known organisms.[1] Excluding fat, water composes approximately 70% of the human body by mass. It is a crucial component of metabolic processes and serves as a solvent for many bodily solutes. The United States Environmental Protection Agency in risk assessment calculations previously assumed that the average American adult ingests 2.0 litres per day.[2] However, the United States Environmental Protection Agency now suggests that either science-based age-specific ranges or an all ages level (based on National Health and Nutrition Examination Survey 2003-2006 data) be used.[3] Bottled water is sold for public consumption throughout the world.

Here are 9 powerful reasons to drink water (with tips on how to form the water habit afterwards):

  1. Weight loss
    Water is one of the best tools for weight loss, first of all because it often replaces high-calorie drinks like soda and juice and alcohol with a drink that doesn''t have any calories. But it''s also a great appetite suppressant, and often when we think we''re hungry, we''re actually just thirsty. Water has no fat, no calories, no carbs, no sugar. Drink plenty to help your weight-loss regimen.

  2. Heart healthy
    Drinking a good amount of water could lower your risks of a heart attack. A six-year study published in the May 1, 2002 American Journal of Epidemiology found that those who drink more than 5 glasses of water a day were 41% less likely to die from a heart attack during the study period than those who drank less than two glasses.

  3. Energy
    Being dehydrated can sap your energy and make you feel tired -- even mild dehydration of as little as 1 or 2 percent of your body weight. If you''re thirsty, you''re already dehydrated -- and this can lead to fatigue, muscle weakness, dizziness and other symptoms.

  4. Headache cure
    Another symptom of dehydration is headaches. In fact, often when we have headaches it''s simply a matter of not drinking enough water. There are lots of other causes of headaches of course, but dehydration is a common one.

  5. Healthy skin
    Drinking water can clear up your skin and people often report a healthy glow after drinking water. It won''t happen overnight, of course, but just a week of drinking a healthy amount of water can have good effects on your skin.

  6. Digestive problems
    Our digestive systems need a good amount of water to digest food properly. Often water can help cure stomach acid problems, and water along with fiber can cure constipation (often a result of dehydration).

  7. Cleansing
    Water is used by the body to help flush out toxins and waste products from the body.

  8. Cancer risk
    Related to the digestive system item above, drinking a healthy amount of water has also been found to reduce the risk of colon cancer by 45%. Drinking lots of water can also reduce the risk of bladder cancer by 50% and potentially reduce the risk of breast cancer.

  9. Better exercise
    Being dehydrated can severely hamper your athletic activities, slowing you down and making it harder to lift weights. Exercise requires additional water, so be sure to hydrate before, during and after exercise.
