How Many Glasses of Water Should We Drink a Day?

Learn How Many Glasses Of Water A Day You NeedBy: Dr. Michael Greger, Director of Public Health and Animal Agriculture at the Humane Society of the United States.

More than 2000 years ago Hippocrates c (460–377 BC) said ‘If we could give every individual the right amount of nourishment and exercise, not too little and not too much, we would have found the safest way to health’. What does that mean when it comes to water? Water has been described as a neglected, unappreciated and under researched subject, but a lot of the papers extolling the need for proper hydration are funded by the bottled water industry. Turns out the often quoted ‘drink at least eight glasses of water a day’ has little underpinning scientific evidence.

Where did they come up with that then? The recommendation was traced back to this 1921 paper, in which the author measured his own pee and sweat and determined we lose about 3% of our body weight in water a day, which comes out to be about 8 cups. Consequently, for the longest time, water requirement guidelines for humanity were based on just one person.

But now there’s evidence suggesting not drinking enough may be associated with falls and fractures, heat stroke, heart disease, lung disorders, kidney disease, kidney stones, bladder and colon cancer, urinary tract infections, constipation, dry mouth, cavities, decreased immune function and cataract formation.

The problem with many of these studies, though, is that low water intake is associated with several unhealthy behaviors, such as low fruit and vegetable intake, more fast-food, less shopping at farmers markets. And think about it—who drinks lots of water? Those that exercise a lot, no wonder they have lower disease rates.

Only large and expensive randomized trials could settle these questions definitively. But given that water cannot be patented, such trials seem unlikely. So we’re left with studies that link disease with low water intake, but are people sick because they drink less, or are they drinking less because they’re sick? There have been a few large prospective studies in which fluid intake is measured before disease develops. For example, a Harvard study of 48,000 men found that the risk of bladder cancer decreased by 7 percent for every extra daily cup of fluid one drinks. So a high intake of water—like 8 cups a day, 8 times 7, may reduce the risk of bladder cancer by about 50 percent, potentially saving thousands of lives.

The accompanying editorial commented that strategies to prevent the most prevalent cancers in the West are remarkably straightforward in principle. To prevent lung cancer, quit smoking; to prevent breast cancer, maintain your ideal body weight and exercise; and to prevent skin cancer, stay out of the sun. Now comes this seemingly simple way to reduce the risk of bladder cancer: drink more fluids.

This is probably the best evidence we have for a cut off. 20,000 men and women in the Adventist Health Study—about half vegetarian, so they were also getting extra water by eating more fruits and vegetables, and those drinking 5 or more glasses of water a day had about half the risk of dying from heart disease compared to those who drank 2 or fewer glasses a day, And like the Harvard study, this protection was after controlling for other factors such as diet and exercise, so they suggest it was the water itself, perhaps by lowering blood viscosity, or thickness.

So based on all the best evidence to date, authorities from Europe, the U.S. Institute of Medicine, and the World Health Organization recommend between 2 to 2.7 liters of water a day for women. That’s 8 to 11 cups a day for women, and 10 to 15 cups a day for men. Now but that’s water from all sources, not just beverages, and we get about a liter from food and the water our body actually makes, and so these translate into a recommendation for women to drink 4 to 7 cups of water a day and men, 6 to 11 cups, assuming only moderate physical activity at moderate ambient temperatures.

We can also get water from all the other drinks we consume, including caffeinated drinks, with the exception of stronger alcoholic drinks like wines and spirits. Beer can leave you with more water than you started with, but wine actively dehydrates you. Note, though, in the cancer and heart disease studies I mentioned, the benefits were only found with increased water consumption, not other beverages, so unless you have conditions like heart or kidney failure, women should drink 4 to 7 cups of water a day and men should drink 6 to 11.

Alkaline Water – The Elixir of Life

Alkaline Water - Elixer of LifeBy Diana Ross, E-RYT 500 Registered Yoga Therapist, Founder of Breast Cancer Yoga

Alkaline water is the start and finish of a life cycle. It is the pillar of all life forms. We are completely dependent on water, as is the planet.  Did you know that water is responsible for our thought processes, feelings, and moods?  Water penetrates through all cell membranes in our body which allows our cell clusters to communicate. It also regulates the functioning of the metabolism, digestion, circulation and assimilation. What is even more amazing is that water is responsible for our consciousness ~ it is the carrier of all physical and mental or non-physical information.

Wow, so why don’t we drink water all the time?

Water has the ability to:

  1. Cleanse the body’s system
  2. Transport nutrients
  3. Remove waste

Then b  y all means we need to drink “The Elixir of Life.”  When we begin to understand the importance of water in our daily lives then we will embrace it with the worth it deserves. Our metabolic functions rely on water. We need it to flush out the kidneys and liver, the skin and lungs – extracting toxins.  Why am I so pumped up about water? Well if you are dealing with breast cancer and had to undergoing chemotherapy or radiation then water is key to recovery. The study on alkaline water and radiation was completed successfully and the results are more than noteworthy. http://clinicaltrials.gov/show/NCT01487954

Now I want to discuss that all waters are not equal and there are different water sources that are better for you than others, for example alkaline water. It hydrates the cells. If we starve the cells of water they will die. Dehydration and poor health follows. Again I repeat – water is a vital force, upon which all life depends. It carries energy and information. The brain is after 90 percent water. Water helps in the flow of bodily fluids like blood and lymph when it moves through our systems. It helps to create energy. It is not the heart that is key to circulation but the forces or flow of our bodily fluids. Water is important to move the body’s fluids up and down so that the heart can remain regulated at a specific frequency pattern (our pulse).

Water is our most important food source. It replenishes and nourishes us. Now why alkaline and not tap water. Drinking water standards may vary from state to state and this testing is suppose to expose potentially harmful impurities or toxins. It has increasingly gotten harder to keep our waters safe from environmental pollutants, pesticides and fungicides so are laws adjust to reflect the additional toxins, and not in our favor.

Our Drinking Waters
There is no doubt that the best water for our health is living, natural, unaltered, mature spring water that is low in minerals. This water is high in life-energy: electromagnetic frequencies and vibration patterns. The same frequencies that resonate with our own body.  We have so many specialty waters to choose from that we can be most confused.

We have:

  • artesian
  • distilled
  • mineral,
  • purified
  • sparkling
  • spring

However, the truth is unnatural waters include sparkling or carbonated and most drinking water. What if you could have it all. The best water, and not have to deal with the recycling of plastics bottles or unethical companies that extract spring waters from small towns. There are some water systems that both clean out the toxins and impurities, and charge the water with negative ions. These are ionic alkaline water systems such as Living Water from Vollara.
