Why is water essential for good health?
• Water gives our cells their shape and form.
• Water helps our body’s delivery system.
• Blood, kidney, heart and lungs are made of about 80% water.
• Since blood is 83% water, it regulates our body temperature when moving from hot to cold or when affected by flu and viruses.
• Bones contain about 22% water.
• Brain tissue is about 85 per cent water.
• Muscle, spleen, brain, intestines, & skin are 72 to 75% water.
• Fat tissue (or adipose tissue) is about 10% water.
• Water is vital to healthy digestion.
• Water rids the body of waste during weight loss and helps metabolize fat more efficiently.
• When the body gets enough water, the feeling of hunger diminishes, eliminating the need for snacking.
Can I tell when my body is thirsty?
• We lose water through urination, respiration, and perspiration. Thirst is linked to hydration, but thirst is a delayed reaction to the body’s need to replenish fluids.
By the time you are feeling thirsty, you are overdue for hydrating.
• Wherever you go, carry a full water container. Get into the habit of continually drinking from your container throughout the day to stay pre-hydrated. If you are not in the habit of drinking the recommended amount of water, increase by gradual increments until you reach the required amounts.
How much water does my body need?
• The amount of water in ounces per day can be estimated by dividing your body weight (in pounds) by 2. That gives you the approximate number of ounces per day that you need to drink.
• On a normal, moderate temperature, inactive day you would lose 1.5 liters (6 glasses) of water through kidney filtration (urine production) and another 0.750 – 1 liter (3 – 4 glasses) through the skin and respiration. So an average person needs 8 – 9 glasses per day just to replace average losses.
• Caffeinated, alcoholic and many carbonated beverages have a diuretic effect and actually increase daily fluid requirements.
• If you exercise you should drink another eight ounce glass of water for every 20 minutes you are active.
• If you drink alcohol, you should drink at least an equal amount of water.
• When you are traveling on an airplane, it is good to drink eight ounces of water for every hour you are on board the plane.
• If you live in an arid climate, you should add another two servings per day.How safe is my tap water?
The Natural Resources Defense Council has identified 5 major hazards in our water:
• Pathogens- bacteria and viruses such as cryptosporidium sicken 900,000 people per year and can be fatal to those with weak immune systems.
• Trihalomethanes- compounds formed when chlorine reacts with organic substances. NRDC estimates that these chemicals cause more than 10,000 cases of bladder and rectal cancers per year.
• Arsenic- The dangers are debated, but 350,000 people may be taking in more than the EPA allows.
• Lead- leading to possible neurological problems in children and high blood pressure in adult men.
• Radioactive contamination- The EPA stated that 50 million Americans drink radon tainted water.
What are my other choices?
• Several studies have confirmed that some bottled water is not in compliance with US drinking water standards. In a recent study, seventeen of 46 samples, representing of 23 brands, contained viable micro-organisms. Bacteria, including coliforms, were recovered from 12 samples of 8 brands. Yeasts or molds were recovered from seven samples of five brands. Free-living amoebas were isolated from two samples, and fresh-water algae were found in both samples of one brand. Nine of 46 samples, representing 7 of the 23 brands contained coliforms. Sterile contact lenses became contaminated when exposed for 1 minute to two of four brands of bottled water from which micro-organisms were recovered.
• A common type of plastic bottle is made with bisphenol- A, also known as BPA. Concerns about tests that may link BPA ingestion with cancer and reproductive damage in some animals and the possibility that BPA could leach out of the plastic bottles and into the liquids they contain has led to bans in some areas on the use of BPA in plastic products intended for children (such as baby bottles) and has prompted some consumers to seek out non-BPA alternatives.
• Bottled water prices vary.
Water filtration at the tap (NSF certified filtration system):
• Saves money making your own clean water.
• Does not add to the landfill or add to recycling costs.
• Allows personal control over the water quality. An NSF certified system can significantly reduce dissolved lead and volatile organic compounds that may be in your water. The treatment system can also reduce cryptosporiium cysts, which have been recognized as one of the most common causes of waterborne diseases within humans in the U.S. (According to the CDC).
