Dehydration : Is your body thirsty? (Part 3)

The human brain, working around the clock, requires more water than any other part of the body. Typically, the brain contains about 20% of of all the blood that circulates through the body. It is estimated that brain cells consist of 85% of water. Their energy requirements are not only met by metabolizing glucose, but also by generating 'hydroelectric' energy from the water drive through cell osmosis. The brain depends greatly on this cell generated source of energy in order to maintain its hugely complex processes and efficiency.

Water deficiency in the brain tissue cuts down the brain's energy supply, and thereby subdues many of its vital functions, a situation most people called depression. With a lower then normal level of energy, you are unable to meet your physical, personal and social challenges and subsequently succumb to fear, anxiety, anger and other emotional affliction. You may feel drained, lethargic, stressed and depressed. Chronic fatigue syndrome, for example, is mostly a symptom of progressive brain dehydration that results from the inability to readily remove all metabolic waste matter and cellular debris from the brain and other vital parts of the body.  Heard of brain fog? Apart from yeast infection which is another cause of brain fog, this is actually an accurate description of the congestion that occurs in the brain. CFS, is not a vicious disease that somehow gets hold of a person for no apparent reason. It may disappear quite spontaneously when the afflicted person stops stimulating the brain with substances such as caffeine, tobacco, medication and begins a consistent program of cleansing, hydrating, and nourishing the body. 

When dehydrated, the body has to put up the fight of a lifetime. similar to the one experienced during a famine or a 'fight or flight' situation. It responds to such a crisis by mobilizing several powerful hormones such as adrenalin, endorphins, cortisol, prolactin, vasopressin and Renin-Angiotensin. I'm sure some of you heard of endorphins, but what it does is it help us to withstand the pain and stress and allow the body to continue most of its activities. Cortisol orders the mobilization of stored energies and essential raw materials to supply the body with energy and basic nutrients during the crisis. This hormone actually allows the body to feed oelf, a situation that is warranted during a famine. Of course, this is also very stressful and potentially very dangerous for the body, as can be seen as such emotional expressions as cannot cope anymore". Many patients with rheumatoid arthritis, MS or other degenerative diseases take cortisone drugs, which often give them a boost of energy and morale for a relatively short period of time. The effect or so called 'success' of the drug, however, only last for as long as the body can tap into any energy and nutrient reserves still available. Once the body has used up its emergency provisions, it will barely function anymore, and the symptoms of disease will worsen considerably.

Now, let's talk abit about blood vessels. When the cells in the body are under-supplied with water, the brain's pituitary gland produces the neurotransmitter vasopressin, a hormone that has the ability to constrict blood vessels in areas where there is cellular dehydration. During dehydration, the quantity of water in the bloodstream is reduced. Vasopressin, as its name suggests, squeezes the vascular system, which includes the capillaries and arteries, to reduce their fluid volume. This maneuver is necessary to continue having enough pressure in the vascular system to allow for a steady filtration of water into the cells. This gives vasopressin a hypertensive property. High blood pressure is a common experience among people who are dehydrated.

A similiar situation occurs in the liver's bile ducts, which begin to constrict in response to water shortage in the body. Gallstone formation is a direct result of dehydration. Drinking alcoholic beverages suppresses the secretion of vasopressin and thereby increases cellular dehydration. If alcohol consumption is excessive, cellular dehydration may reach dangerously high levels.

I'm sure most of us gotten drunk and experienced 'hangover' before. The typical hangover that occurs after alcoholic abuse is nothing but an extreme state of dehydration of the brain cells. To survive the alcohol-induced 'drought', the body has to secrete more stress hormones, among them are the addictive endorphins. With regular consumption of alcohol such as daily drinking for several months or years, dehydration increases even further, and endorphin production becomes an addictive occurrence. This may lead of alcoholism, a disease that has devastating consequences on a person's personal and social life. Sadly, me myself have known quite a few such people.

Next, let's discuss about water retention and how it link to kidney damage. First of all, the Renin-Angiotensin system becomes activated whenever there is a shortage of water in the body. This brilliantly designed system is used to direct the body to hold on to water whenever possible. it instructs the kidneys to inhibit urination and tightens the capillaries and the vascular system, particularly in areas that are not as vitally important as the brain and the heart muscles. At the same time, it stimulates an increase in the absorption of sodium(salt), which helps the body to retain water. Unless the body returns to its normal level of hydration, the RA system remains activated. But this also means that the pressure of the blood against the walls of the blood vessels remains abnormally high, thereby causing the damage that is known as cardiovascular disease.

Bear in mind, that hypertension and the retention of urine in the kidneys may lead to kidney damage. Conventional treatments for this condition consists mostly of diuretic drugs and restricted salt consumption. Please take note that both can  have severe drawbacks. Diuretic drugs, which are used to normalized blood pressure, as well as reduced salt intake, strongly undermine the body's emergency measures to save the little water it has left for normal cellular activities. The resulting stress response causes a further increase in dehydration, and the vicious cycle is complete. Many of the kidney transplant performed today are a result of chronic dehydration, which is caused by something as simple as not drinking enough water, consumption of alcohol, and overstimulation of the nervous system.

Moving on, let's talk about caffeine and soft drinks. Many people tend to rely on coffee or other caffeinated beverages to keep up their energy levels day in day out. A cup of coffee in the morning, and a few more cups throughout the day  to keep them 'focused' and able to stay up during daytime. The caffeine contained in such beverages as tea, coffee, soft drinks and most 'power drinks', not only stimulates and stresses both the central nervous systems, but also acts as a powerful diuretic.

For every cup of coffee or tea you drink, your body has to relinquish up to three cups of water to remove the toxic caffeine. Yes, you read it right, three cups of vital fluid from your body! Wonder why you hit the toilet so often?  The caffeine containing soft drink beverages work in a similar way too. Caffeine, being a nerve toxin, stimulates the adrenal glands to secrete stress hormones and to trigger a strong immune response that may give you the false impression that this newly found energy and vitality was somehow provided by the consumed beverage.

The secret behind this stimulants is that the immune reaction mobilizes enough energy for you to feel perked up and clear-headed, at least for as long as your body remained stimulated. To remove the caffeine from the blood, the body is forced to take or sacrifice the water from its cells. This results in cellular dehydration and temporary thinning of the blood. Because the thinning of the blood makes you feel good, you won't notice the imminent danger of dehydration. The dehydrating effect of the caffeine in soft drinks is ample reason to avoid them. Unfortunately, caffeine is not the only culprit in soft drinks.

I've blogged before about soft drink beverages, how damaging these drinks are to human body and explained why we should not be drinking it. There are evidence in studies confirm that soft drinks cause serious cells damage. Research from a British university suggests a common preservative found in drinks such as Coca-Cola, Pepsi, Fanta has the ability to switch off vital parts of DNA. This can eventually lead to cirrhosis of the liver and degenerative diseases such as Parkinson's. The findings reveal serious consequences for the hundreds of millions of people worldwide who consume carbonated beverages.

Check this out. The biggest concern is the safety of E211, also known as sodium benzoate, a preservative used to decades in global carbonated soft drinks industry. Sodium benzoate derives from benzoic acid. It is used in large quantities to prevent mold from forming in soft drinks such as Sprite, Dr.Pepper and others. This common preservative is also added to pickles and sauces.

In the past, sodium benzoate had already been identified as indirect cause of cancer. When mix with additive of Vitamin C in soft drinks, it produces benzene, a carcinogenic substance. It is known that sodium benzoate damage an important area of DNA power station of cells also known as mitochondria. These chemicals have the ability to cause severe damage to DNA in the mitochondria to the point that they totally inactivate it and knock it out altogether. The mitochondria  consumes oxygen and gives you the energy and if you damage it, then the cells starts to malfunction very seriously. And there is a whole array of diseases that are now being tied to damage to the DNA. Some of the diseases such as Parkinson's and quite alot of other neuro-degenerative diseases, but above all, the whole process of aging.

For whoever reading this, it is now up to you to protect yourself and your loved ones. Not allowing your children or loved ones to drink soft drinks is one of the most important things you can do for their safety and good health. And of course, yourself must set a good example for your loved ones and ensure no soft drinks are in the refrigerator at all times. The same applies with sport drinks which, according to a report issued by University of Californian in Berkeley, can raise body weight to a stunning 13 pounds each year, if only 20 ounce bottle is consumed daily. 

Over the long term, the effects of the acidity, sugars, artificial sweeteners and flavors, and such preservatives as E211 contained in soft drinks can be devastating to the body. Check this out. It would take 32 glasses of water at an alkaline pH of 9 to neutralize the acid from just one 12oz of cola or any other soda/soft drinks. In response to ingesting a cola, apart from risking dehydration, the body will have to use the reserves of its own stored alkaline buffers, mainly calcium from the bones, teeth and DNA. This raises the body alkalinity levels in order to maintain proper blood alkaline pH levels. Once these reserves are exhausted, your life is at risk.

Remember, there are enough acids in one soda to kill you, if your body didn't posses a mechanism to neutralize them. How long does it takes before your body succumbs to the acid attack and suffers an acidosis depends upon how soon your mineral buffers are depleted. Acidic blood levels are one of the leading cause of death!

Before I sign off this post, always remember, caffeine, which is a major component in most soft drinks, removes water from the body faster then the body can absorb it again, thereby generating constant thirst. People who frequently drink soft drinks are never really able to really quench their thirst because their bodies continually and increasingly run out of cellular water. Stay tune for the final post of this topic as I need to logoff and hit the bed now.
