Are you drinking enough water? Can one drink too much water? Some swear by eight glasses of eight ounces of water per day to stay healthy and hydrated. Others say more, and others say less, how does one know how much to drink? What information can one access that has been scientifically tested and proven, and what is pseudoscience? The truth is, many people are not knowledgeable on the correct daily intake of water, and worse yet they are being told information that has no scientific backing. So then, the question remains, how much water should one be drinking? The answer? It depends…

A study done by Heinz Valtin tests the validity of the 8 x 8 routine for daily water intake. With comprehensive search of literature, Valtin has emerged empty handed; there is yet to be a traceable recommendation of the 8 x 8 rule based on solid scientific evidence. Digging deeper into the legitimacy of the 8 x 8 recommendation, Valtin does more research to uncover data. A study conducted by the United States Department of Agriculture reveals that the average person was consuming near, at, or above the eight by eight ounces of fluid per day since the 8 x 8 recommendation has been popularized. Yet this is still not enough because the average ingestion of fluids included coffee, tea, juice, milk, mild alcoholic beverages and other liquids, not solely water. Excluding the amount of fluid dictated as invalid, people were only consuming around half the water the 8 x 8 routine is recommending. Are we to consume extra water on top of all the fluids we already intake?

Are you being unhealthy by not consuming eight glasses of eight ounces of water per day? In short, probably not. As of late there has been no scientific reports that conclude that we must consume eight glasses of eight ounces of water per day. Is there scientific evidence that we should not drink this much water? There is highly suggestive evidence, but no proof. There are publications that state the opposite of the 8 x 8 recommendation, and drinking that much water could possibly be harmful. The 8 x 8 recommendation can make one feel guilty for not reaching the amount of water ‘needed’, can induce hyponatremia, and exposure to pollutants in the water. However, one should know when they are dehydrated. In some instances, a way of monitoring hydration levels is to keep track of urine color and volume. To be very laymen, the more pale or clear urine is, the better one’s hydration levels. The darker urine appears, the more one should consider drinking water to rehydrate.

Valtin has found no scientific proof that one must drink at least eight glasses of water a day, nor proof that drinking less does unquestionably no harm. However, the published data accessible as of now strongly suggest that we are probably drinking enough, and possibly even more than enough water (under most circumstances).

These recommendations are concerned with fluid intake for healthy adults who live in a temperate climate, and perform mild exercise at most. People who live in warmer climates or participate in higher intensities of physical activity will undoubtable need to consume more water than someone who is sedentary.
