Water 101

Water is the most precious––and most common––chemical compound on earth,

and in our bodies.

by Mia White



The human brain and heart are 73% water, the lungs are 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even our bones are 31% water!  Many marine invertebrates are 96% water and the human embryo is 93 % water.

Every single one of our bodily processes relies on water:  It regulates our body’s temperature, fuels the function of our blood, lymph, and filter organs to deliver nutrients and remove wastes and pathogens, keeps our skin and muscles pliable, helps to carry nerve signals throughout the body, helps protect the spinal cord, and it acts as a lubricant and cushion for our joints, eyes, and brain.



There are two popular formulas:

  1. The first is called the “8 x 8 rule,” so it’s easy to remember. Eight 8-oz glasses of water per day is recommended for an average adolescent, teenager, and adult (about 2 liters).
  2. The other formula is based on your body weight: divide your weight by 2/3––that’s the number of ounces of water recommended per day for you.  For example, 150 lbs. ÷ 2/3 = 100 ounces, or about 3 liters, which is closer to 12 8-oz glasses of water. Hmmm.

I think the body-weight formula makes the most sense, but of course there are other factors to consider when gauging how much to drink:

  • How much exercise am I getting today? If a lot, then more water; if not so much, then perhaps less.
  • How much fresh juicy produce did I eat today? Fresh fruit and vegetables have a high water content, so they can be factored in.
  • Some other beverages–like fresh unsweetened fruit and vegetable juices and herbal tea––can be considered part of your optimal fluid intake per day, but NOT coffee, alcohol, sugary drinks or carbonated drinks. These can actually have the opposite effect that clean fresh water has on your body, requiring more water to flush them out.
  • What kind of climate do I live in? If cool and moist––think Seattle––then you won’t dehydrate as quickly as if you live in a hot, dry climate such as Arizona.
  • Are you pregnant? Drink a lot more!  That 30 pounds you’re gaining to have an 8-lb. baby is mostly fluid needed to produce extra blood, amniotic fluid, and to support all the other processes of the pregnancy.
  • Remember, winter air is dryer than summer air, so it’s important to keep up your fluid intake, even though you might not feel as thirsty as when you’re hot.



As important as how much water to drink is the quality of the water itself.  As Dr. Mercola says, “If you don’t filter your water, you become the filter.”  And you can’t rely on taste and smell alone to tell you if your water is pure enough to drink.  Everything that goes down your drains, gets flushed down your toilets and washed into storm drains––including medications, heavy metals, pesticides, VOCs and more––winds up in our waste water treatment plants, and they cannot filter it all out.   In addition, a water treatment facility uses chemicals such as chlorine to destroy harmful bacteria, and these chemicals are not healthy for our consumption, to absorb through our skin in the tub or shower, or to breathe the vapors they put into our air.


THE BEST:  In my research, Aquasana makes the most effective and affordable line of water filters, removing up to 99.99% of dozens of contaminants. Filtering kitchen drinking/cooking water and shower heads is essential, but if you can manage a whole-house filter, all the better. I also love the Berkey or Propur countertop stand-alone systems.


NOT SO GOOD: Pitcher-style  filters (such as Britta)do not remove nearly as many contaminants and are actually much more expensive per gallon than a good system attached above or under your kitchen sink. Reverse osmosis units are pricey and high-maintenance, use several gallons of water for each filtered gallon produced, and filter out beneficial minerals, as does distillation.



THE BEST: Some of the top-recommended brands of reusable water bottles are Hydro Flask (stainless steel—thermal), Kleen Kanteen (stainless steel—non-thermal), and Lifefactory (glass with a shatterproof silicone sleeve––I’ve dropped mine a dozen times!). I like the Lifefactory bottles because I can see easily see inside them to make sure they’re clean. And they offer lots of pretty colors to choose from!


NOT SO GOOD: Most plastic-bottled water contains a range of impurities, including BPA from the bottle itself.  Plastic bottles also put a lot of BPA and other chemicals into into the environment during manufacturing and post-use, and are clogging up our landfills and oceans, so please join the many countries, universities, national parks, and other organizations in their ban on plastic water bottles, by using only non-toxic refillable water bottles made of glass or stainless steel, filled up with the great filtered water from your home filter system!
