I have always been a firm believer in the more water you drink, the healthier you are. I never had any sort of scientific proof to back up this belief. I just knew that whenever I drank more water, my head and body always felt better. Plus, the more water I drank, the less likely I were to fill my body with food or drinks high in calories.
So just how much water are you suppose to drink for it to be considered healthy? I've read countless articles over the years stating that the average person should aim to drink 64 ounces of water a day. That equals out to be eight, 8-ounce glasses of water each day. But is drinking 64 ounces of water necessary in order to maintain a clean bill of health?
According to the
Scientific American, there is no scientific proof that drinking 64 ounces of water a day provides a healthy benefit to the body.
Heinz Valtin, a retired professor of physiology from Dartmouth Medical School says that the only people who truly benefit from drinking large amounts of water a day are people who suffer from kidney stones, urinary tract infections, people who perform strenuous activity, endure long airplane flights or are in a hot weather climate.
The body is 60-70% water. It's true that your body needs water to function properly.
Dr. Stanley Goldfarb, a kidney expert at the University of Pennsylvania believes that when it comes to water consumption, more is not necessarily healthier. You can die from consuming too much water. Kidneys filter toxins. Toxins clear through urine. If there is a large quantity of water in the body, it can reduce the kidney's ability to function as a filter therefore leading to "water intoxication."
Some believe that drinking large quantities of water will also help clear out the toxins from your skin, therefore clearing your skin from any blemishes or future breakouts. In
Dr. Stanley Goldfarb's full editorial which was published in the April 2008 issue of the
Journal of the American Society of Nephrology, the only thing drinking water does for the skin is increase capillary blood flow. Drinking water will certainly help to hydrate the inside of the body, but there's no proof that drinking more water hydrates the skin. Even though the skin is the largest organ of the body, its the last place to receive any hydrating benefits from ingesting water. The best way to hydrate the skin is to apply products topically.
There's is also a popular belief that the more water a person drinks, the more weight they will lose. "Water is a great strategy for dieters because it has no calories," says
Madeline Fernstrom of the University of Pittsburgh. "So you can keep your mouth busy without food and get the sense of satisfaction." A person can not drink their way to a skinnier self. Drinking water only works, in terms of weight loss, when a person chooses to drink water instead of a caloric beverage.
When it comes down to it, the only thing that really matters is "everything in moderation." Too much of a good thing can be dangerous and even sometimes lethal. Don't drink a ton of water each day just because you want to
(1) lose weight,
(2) have clear skin,
(3) flush the toxins out of your body or because
(4) some article you read in the break room told you that you had to drink a certain amount of water each day in order to be healthy. It's really much simpler than that.
Drink water because you're thirsty.
