Benefits & Dangers of Water

Benefits of Water

Drinking a healthy amount of water is vital to your health. You can never imagine just by changing this simple step, you gain tremendous health benefits, and sometimes you can even throw away your migraine medicine or pain killer.  You can live a week without food, but not without water...that should say a lot!

Before you can appreciate the benefits of water to your health, let’s review the role of water in the human body.

Functions of Water in The Body

The human body is anywhere from 55% to 78% water depending on body size. A rule of thumb, 2/3 of the body consists of water, and it is the main component of the human body. Did you know that your tissues and organs are mainly made up of water?
Here is the %:

  • Brain consists of 90% of water
  • Blood consists of 83% water
  • Muscle consists of 75% water
  • Bone consists of 22% of water
The functions of water in the human body are vital. The water:
  • Transports nutrients and oxygen into cells
  • Moisturizes the air in the lungs
  • Helps with metabolism
  • Protect our vital organs
  • Helps our organs to absorb nutrients better
  • Regulates body temperature
  • Detoxifies
  • Protect and moisturizes our joints and skin
Every cell in your body needs water from head to toe. That is why it is so important to drink enough fluid, especially when you are ill. Take for example, the brain consists of 90% of water, if you do not supply enough water to your body, your brain cannot function well, and you will get a headache or migraine. Hence, next time, if you feel fatigued or have a headache, it may be the sign of dehydration.


 

Harmful Effects and Symptoms of Dehydration

The Harmful Effects Result from Dehydration are:
  • Tiredness
  • Migraine
  • Constipation
  • Muscle cramps
  • Irregular blood-pressure
  • Kidney problems
  • Dry skin
  • 20% dehydrated – Risk of death
Symptoms of Dehydration
Here are some of the symptoms that signal you need more water:
  • Dark Urine – Dark Yellow or Orange in Color: Urine is generally pale yellow to clear when you have sufficient water intake. Dark color or smell strong indicates that you need to drink more water. Note: some medications or supplements may change the color as well. Such as high vitamin B will turn your urine neon bright yellow even when very well hydrated, this should not cause for alarm.
  • Dry Skin: Skin is the largest body organ and requires its share of water.
  • Thirst: Thirst is the most obvious sign that you're already dehydrated. It is always a good practice to drink more water when your are not thirsty, don’t wait until you're thirsty.
  • Hunger: Most people mistaken hungry as the indication to eat more, whereas in actual fact, you may be dehydrated. So before you have your snack, grab a glass of water.
  • Fatigue: Water is a source of energy, it gives you a boost in energy.

 

How much water should you drink a day to avoid dehydration? 

A common approach is drinking 8 glasses of water a day, is it sufficient?

There is no clear-cut answer as to how much water to drink per day, because it depends upon a number of factors like your health condition, your activity status, the climatic conditions, physical size, your weight and your environment etc. You lose quite a lot of water through sweating, exhaling and urinating. In hot weather, you tend to lose more water through sweating, in cold condition, you tend to urinate more. In the event of sickness like flu and diarrhea, you tend to lose fluid. When you weigh more, your body needs more fluid for the muscle, organ, bone etc.

There are many recommendations advise that you drink 8 glasses (250ml/8 ounce per glass = total of approx 2 liter) of water a day. But is drinking 8 glasses of water enough? Remove the environmental, climatic factors and your activity level out of the equation, the amount of water intake is vary according to your weight. A more accurate estimation is to drink at least half your body weight (in pounds) in ounces of water. Let's illustrate with the following example:
1. If you weigh 160 pounds.
160 ÷ 2 = 80 (amount of water to drink in ounce per day)
Answer: Drink 80 ounce of water per day.
Which is ten 8 oz glasses of water
If you weigh 125lbs then eight 8 oz glasses of water is sufficient. 



 

Top 11 Health Benefits of Drinking Water

You will be amazed of the benefits of drinking water as follow:
Some are mentioned above...
  1. Lose weight: Drinking water helps you lose weight because it flushes down the by-products of fat breakdown. Drinking water reduces hunger, it’s an effective appetite suppressant so you’ll eat less. Plus, water has zero calories. Here are the further details on how to achieve fat loss by drinking water.
  2. Natural Remedy for Headache: Helps to relieve headache and back pains due to dehydration. Although there are many other reasons contribute to headache, dehydration is the common one.
  3. Look Younger with Healthier Skin: You’ll look younger when your skin is properly hydrated. Water helps to replenish skin tissues, moisturizes skin and increase skin elasticity.
  4. Better Productivity at Work: Your brain is mostly made up of water, thus drinking water helps you think better, be more alert and more concentrate.
  5. Better Exercise: Drinking water regulates your body temperature. You’ll feel more energetic when doing exercises and water helps to fuel your muscle.
  6. Helps in Digestion and Constipation: Drinking water raises your metabolism because it helps in digestion. Fiber and water goes hand in hand so that you can have your daily bowel movement.  So you want to drink water with nigh fiber foods.
  7. Less Cramps and Sprains: Proper hydration helps keep your joints and muscles lubricated, so you’ll less likely get cramps and sprains.
  8. Less Likely to Get Sick to Feel Healthy: Drinking plenty of water helps fight against flu and other ailments like kidney stones and heart attack. Water adds with lemon is used for ailments like respiratory disease, intestinal problems, rheumatism and arthritis etc. Another words one of the benefits of drinking water can improve our immune system. Follow this link for further information on how lemon water can improve your health.
  9. Relieves Fatigue: Water is used by the body to help flush out toxins and waste products from the body. If your body lacks water, your heart, for instance, needs to work harder to pump out the oxygenated blood to all cells, so does the rest of the vital organs, your organs will be exhausted and so are you.
  10. Good Mood: Your body feels very good and that’s why you feel happy.
  11. Reduce the Risk of Cancer: Related to the digestive system, some studies show that drinking a healthy amount of water may reduce the risks of bladder cancer and colon cancer. Water dilutes the concentration of cancer-causing agents in the urine and shortens the time in which they are in contact with bladder lining.
Can you see the importance of water to your body after understanding the above benefits of drinking water?  Hopefully:) So drink up!

10 Facts about Fluoride
Resource- Fluoride Action Network

1) 97% of western Europe has chosen fluoride-free water . This includes: Austria, Belgium, Denmark, Finland, France, Germany, Iceland, Italy, Luxembourg, Netherlands, Northern Ireland, Norway, Scotland, Sweden, and Switzerland. (While some European countries add fluoride to salt, the majority do not.) Thus, rather than mandating fluoride treatment for the whole population, western Europe allows individuals the right to choose, or refuse, fluoride.

2) Fluoride is the only chemical added to drinking water for the purpose of medication (to prevent tooth decay). All other treatment chemicals are added to treat the water (to improve the water's quality and safety - which fluoride does not do). This is one of the reasons why most of Europe has rejected fluoridation. For instance:
In Germany, "The argumentation of the Federal Ministry of Health against a general permission of fluoridation of drinking water is the problematic nature of compulsion medication."
In Belgium, it is "the fundamental position of the drinking water sector that it is not its task to deliver medicinal treatment to people. This is the sole responsibility of health services."
In Luxembourg, "In our views, drinking water isn't the suitable way for medicinal treatment and that people needing an addition of fluoride can decide by their own to use the most appropriate way."

3) Contrary to previous belief, fluoride has minimal benefit when swallowed. When water fluoridation began in the 1940s and '50s, dentists believed that fluoride needed to be swallowed in order to be most effective. This belief, however, has now been discredited by an extensive body of modern research (1).
According to the Centers for Disease Control, fluoride's "predominant effect is posteruptive and topical" (2). In other words, any benefits that accrue from the use of fluoride, come from the direct application of fluoride to the outside of teeth (after they have erupted into the mouth) and not from ingestion. There is no need, therefore, to expose all other tissues to fluoride by swallowing it.

4) Fluoridated water is no longer recommended for babies. In November of 2006, the American Dental Association (ADA) advised that parents should avoid giving babies fluoridated water (3). Other dental researchers have made similar recommendations over the past decade (4).
Babies exposed to fluoride are at high risk of developing dental fluorosis - a permanent tooth defect caused by fluoride damaging the cells which form the teeth (5). Other tissues in the body may also be affected by early-life exposures to fluoride. According to a recent review published in the medical journal The Lancet, fluoride may damage the developing brain, causing learning deficits and other problems (6).

5) There are better ways of delivering fluoride than adding it to water. By adding fluoride to everyone's tap water, many infants and other at-risk populations will be put in harm's way. This is not only wrong, it is unnecessary. As western Europe has demonstrated, there are many equally effective and less-intrusive ways of delivering fluoride to people who actually want it. For example:
A) Topical fluoride products such as toothpaste and mouthrinses (which come with explicit instructions not to swallow) are readily available at all grocery stores and pharmacies. Thus, for those individuals who wish to use fluoride, it is very easy to find and very inexpensive to buy.
B) If there is concern that some people in the community cannot afford to purchase fluoride toothpaste (a family-size tube of toothpaste costs as little as $2 to $3), the money saved by not fluoridating the water can be spent subsidizing topical fluoride products (or non-fluoride alternatives) for those families in need.
C) The vast majority of fluoride added to water supplies is wasted, since over 99% of tap water is not actually consumed by a human being. It is used instead to wash cars, water the lawn, wash dishes, flush toilets, etc.

6) Ingestion of fluoride has little benefit, but many risks. Whereas fluoride's benefits come from topical contact with teeth, its risks to health (which involve many more tissues than the teeth) result from being swallowed.
Adverse effects from fluoride ingestion have been associated with doses atttainable by people living in fluoridated areas. For example:
a) Risk to the brain. According to the National Research Council (NRC), fluoride can damage the brain. Animal studies conducted in the 1990s by EPA scientists found dementia-like effects at the same concentration (1 ppm) used to fluoridate water, while human studies have found adverse effects on IQ at levels as low as 0.9 ppm among children with nutrient deficiencies, and 1.8 ppm among children with adequate nutrient intake. (7-10)

b) Risk to the thyroid gland. According to the NRC, fluoride is an “endocrine disrupter.” Most notably, the NRC has warned that doses of fluoride (0.01-0.03 mg/kg/day) achievable by drinking fluoridated water, may reduce the function of the thyroid among individuals with low-iodine intake. Reduction of thyroid activity can lead to loss of mental acuity, depression and weight gain (11)
c) Risk to bones. According to the NRC, fluoride can diminish bone strength and increase the risk for bone fracture. While the NRC was unable to determine what level of fluoride is safe for bones, it noted that the best available information suggests that fracture risk may be increased at levels as low 1.5 ppm, which is only slightly higher than the concentration (0.7-1.2 ppm) added to water for fluoridation. (12)
d) Risk for bone cancer. Animal and human studies – including a recent study from a team of Harvard scientists – have found a connection between fluoride and a serious form of bone cancer (osteosarcoma) in males under the age of 20. The connection between fluoride and osteosarcoma has been described by the National Toxicology Program as "biologically plausible." Up to half of adolescents who develop osteosarcoma die within a few years of diagnosis. (13-16)
e) Risk to kidney patients. People with kidney disease have a heightened susceptibility to fluoride toxicity. The heightened risk stems from an impaired ability to excrete fluoride from the body. As a result, toxic levels of fluoride can accumulate in the bones, intensify the toxicity of aluminum build-up, and cause or exacerbate a painful bone disease known as renal osteodystrophy. (17-19)

7) The industrial chemicals used to fluoridate water may present unique health risks not found with naturally-occurring fluoride complexes . The chemicals - fluorosilicic acid, sodium silicofluoride, and sodium fluoride - used to fluoridate drinking water are industrial waste products from the phosphate fertilizer industry. Of these chemicals, fluorosilicic acid (FSA) is the most widely used. FSA is a corrosive acid which has been linked to higher blood lead levels in children. A recent study from the University of North Carolina found that FSA can - in combination with chlorinated compounds - leach lead from brass joints in water pipes, while a recent study from the University of Maryland suggests that the effect of fluoridation chemicals on blood lead levels may be greatest in houses built prior to 1946. Lead is a neurotoxin that can cause learning disabilities and behavioral problems in children. (20-23)

8) Water fluoridation’s benefits to teeth have been exaggerated. Even proponents of water fluoridation admit that it is not as effective as it was once claimed to be. While proponents still believe in its effectiveness, a growing number of studies strongly question this assessment. (24-46) According to a systematic review published by the Ontario Ministry of Health and Long Term Care, "The magnitude of [fluoridation's] effect is not large in absolute terms, is often not statistically significant and may not be of clinical significance." (36)
a) No difference exists in tooth decay between fluoridated & unfluoridated countries. While water fluoridation is often credited with causing the reduction in tooth decay that has occurred in the US over the past 50 years, the same reductions in tooth decay have occurred in all western countries, most of which have never added fluoride to their water. The vast majority of western Europe has rejected water fluoridation. Yet, according to comprehensive data from the World Health Organization, their tooth decay rates are just as low, and, in fact, often lower than the tooth decay rates in the US. (25, 35, 44)
b) Cavities do not increase when fluoridation stops. In contrast to earlier findings, five studies published since 2000 have reported no increase in tooth decay in communities which have ended fluoridation. (37-41)
c) Fluoridation does not prevent oral health crises in low-income areas. While some allege that fluoridation is especially effective for low-income communities, there is very little evidence to support this claim. According to a recent systematic review from the British government, "The evidence about [fluoridation] reducing inequalities in dental health was of poor quality, contradictory and unreliable." (45) In the United States, severe dental crises are occurring in low-income areas irrespective of whether the community has fluoride added to its water supply. (46) In addition, several studies have confirmed that the incidence of severe tooth decay in children (“baby bottle tooth decay”) is not significantly different in fluoridated vs unfluoridated areas. (27,32,42) Thus, despite some emotionally-based claims to the contrary, water fluoridation does not prevent the oral health problems related to poverty and lack of dental-care access.

9) Fluoridation poses added burden and risk to low-income communities. Rather than being particularly beneficial to low-income communities, fluoridation is particularly burdensome and harmful. For example:
a) Low-income families are least able to avoid fluoridated water. Due to the high costs of buying bottled water or expensive water filters, low-income households will be least able to avoid fluoride once it's added to the water. As a result, low-income families will be least capable of following ADA’s recommendation that infants should not receive fluoridated water. This may explain why African American children have been found to suffer the highest rates of disfiguring dental fluorosis in the US. (47)
b) Low-income families at greater risk of fluoride toxicity. In addition, it is now well established that individuals with inadequate nutrient intake have a significantly increased susceptibility to fluoride’s toxic effects. (48-51) Since nutrient deficiencies are most common in low-income communities, and since diseases known to increase susceptibility to fluoride are most prevalent in low-income areas (e.g. end-stage renal failure), it is likely that low-income communities will be at greatest risk from suffering adverse effects associated with fluoride exposure. According to Dr. Kathleen Thiessen, a member of the National Research Council's review of fluoride toxicity: “I would expect low-income communities to be more vulnerable to at least some of the effects of drinking fluoridated water." (51)

10) Due to other sources, many people are being over-exposed to fluoride . Unlike when water fluoridation first began, Americans are now receiving fluoride from many other sources* besides the water supply. As a result many people are now exceeding the recommended daily intake, putting them at elevated risk of suffering toxic effects. For example, many children ingest more fluoride from toothpaste alone than is considered “optimal” for a full day’s worth of ingestion. According to the Journal of Public Health Dentistry:
"Virtually all authors have noted that some children could ingest more fluoride from [toothpaste] alone than is recommended as a total daily fluoride ingestion." (52)
Because of the increase in fluoride exposure from all sources combined, the rate of dental fluorosis (a visible indicator of over-exposure to fluoride during childhood) has increased significantly over the past 50 years. Whereas dental fluorosis used to impact less than 10% of children in the 1940s, the latest national survey found that it now affects over 30% of children.
* Sources of fluoride include: fluoride dental products, fluoride pesticides, fluoridated pharmaceuticals, processed foods made with fluoridated water, and tea.(47, 53)
