Stress - How it creates havoc for our health.

Stress can be caused from a wide array of bad lifestyle choices and difficult circumstances. Stress is mostly unavoidable in the modern age. From a health perspective, when we are talking about stress we are making the distinction between stress and feeling overwhelmed. The majority of us have many stressors in our lives, but we don't consider ourselves to be suffering from stress. However this feeling of being "stressed" is what we would call feeling overwhelmed which is usually experienced once stress levels start to get really high. In daily life a certain amount of stress can be useful, however if you have filled your life with work and family commitments plus social commitments, charity work etc and couple it with inadequate relaxation time and less than amazing nutrition - even if you're coping well with it all - it's a recipe that we call stress. If our daily lives are filled with the body combating many stressors, then there is very limited leeway for dealing with life's challenges that inevitably come our way.

One of the least understood and unrecognised aspects of stress are that stress includes physical, chemical, emotional and electromagnetic factors. The major stressors follow:

Physical                                                   Chemical              
Inactivity                                                  Sugar      
Toxins (including drugs,                             Infection
Pesticides, additives, immunizations ect)    Nutritional Imbalance
Inadequate light                                        Nicotine
Allergens                                                 Caffeine
Temperature extremes                              Alcohol
Trauma                                                    Xeno-estrogens from plastics
No sunshine for at least an hour a day
Being indoors in “managed” air
Sleeping outside of our natural circadian rhythm

Emotional                                               Electromagnetic     - Positive ions  
Fear                                                       Mobiles              
Anger                                                     Refrigerators, microwaves      
Guilt                                                       Television
Anxiety                                                  Computers
Depression                                             Printers, photocopiers      
Pain                                                       Airplanes
Inadequate sleep, shift work (sleeping     Fluorescent lights
during the day)
Lack of meaning or purpose in life
1. (Shealy, pg.7, 1996)

Normally the body is able to balance these stressors, and align the body to a homeostatic level. However, if stress continues the body can adapt, which changes the efficiency of the stress reaction. Every time we adapt to one stressor, whether it be nicotine, electromagnetic radiation, inadequate sleep ect, then we lower our threshold for a new stressor. 2. (Selye,1974)

A non coffee drinking individual would ordinarily require a cup of coffee to double norepinephrine production, and someone who has adapted to cigarettes might only require two-thirds or half a cup of coffee. When you have adapted to three or four stressors, or even hundreds, it may take less than half as much of a new stress to cause an alarm reaction. The Stress builds up, and we become vulnerable to small stressors more and more.

Even though we become vulnerable to stress, interestingly enough we can also become addicted to the sensation of stress, especially if we grew up in a stressful environment, or were encouraged to place ourselves in stressful situations as teenagers to achieve success, higher grades, accolades and for winning competitions.
The neurotransmitter serotonin is also elevated during stressful times. Serrotinin tends to make us feel satiated or satisfied, and also makes us feel slightly euphoric. The release of high levels of serritonin could be a link to our addiction to stress.

Like caffeine, when Serotonin is released it triggers the release of adrenaline, which allows the body to work through the stress, as It kick starts our sympathetic nervous system (the Fight or Flight response) which quickens the heart rate, elevates blood pressure, increases our sensitivity to pain, light, sound and smell, increases aggression and speeds up mental activity.

This is obviously useful in life or death situations, and in stressful circumstances that we can not avoid. However, when we get bombarded by exogenous stressors mentioned in the chart above then we start to tax the body in many ways, which leads to a long list of health issues.

An overproduction of adrenaline causes nervousness, panic attacks, anxiety, phobias, extreme mood swings and bouts of aggression.  Also, as adrenalin is not quickly renewed,  if we become addicted to the sensation of serotonin and adrenalin in the body, stress, and or caffeine for that matter, for long duration's, our adrenal reserves get used up. This leads to symptoms of exhaustion, anxiety and depression, known as adrenal fatigue.

Over time the serotonin levels can decrease and we may develop a deficiency of Serotonin in the brain which can cause depression (now causes by adrenal fatigue and low serotonin) and it can also upset the appetite mechanism which may lead to obesity or other eating disorders such as anorexia and bulimia nervosa and may be responsible for insomnia, as serotonin converts to melatonin which helps us sleep.

A person low in Serotonin will be inclined to consume greater amounts of sugar in an attempt to increase Serotonin production and this may lead to sugar addiction. 3.  (J. Plesman, The serotonin connection). Remembering sugar is an addictive and stressful chemical on the body, which may have gotten us here in the first place. Sugar addiction can then lead to insulin resistance, which causes unstable concentrations of blood glucose, causing fatigue, moodiness and sugar cravings, and can then lead to diabetes over time.

As we eat large amounts of sugar or refined carbohydrates, our insulin levels increase to mop up the sugar. The spike in insulin can also create a spike in some of our hormones known as androgen, mostly androstenedione and testosterone. This can then create hormonal imbalances, which can create PCOS, hirsutism (male hair growth patterns in women), male pattern balding, and over time aromatizes into estrogens. High Estrogens are linked in with incidence of endometriosis, fibroids, cysts, heavy / irregular periods and breast cancer.

This elevated insulin in this circumstance blocks the utilization of fat cells as a source of energy, thus causing obesity, or storing fat around the waist line. Wild fluctuations in blood sugar levels causes the body to produce excess adrenaline, once again.  The cycle continues.

These interrelationships of stress are almost certainly a prime contributor to the body’s loss of homeostasis and a gradual progression of chronic stress adaptation-maladaptation-exhaustion stages. It is probable that by the time you adapt to any given stress that it will be difficult for you body to maintain in balance in all hormonal levels.

The results of Chronic Stresss (Exhaustion)

Stress hormone Cortisol increases 24 hours a day
Sex hormone DHEA decreases
Insulin erratic (metabolic fluctuation)
Poor sleep recovery
Immune system significantly deficient
Major illnesses begin
-    Heart disease
-    Stroke
-    Cancer
-    Infection
-    Autoimmune disorders
-    Degenerative diseases

Although research shows a strong correlation between chemical, physical and emotional stress and patients diverse symptoms, most physicians do not evaluate even the most basic measures of stress, or address hormonal fluctuations.

When Cortisol (our stress hormone) is elevated in our body’s from Chronic stress and from the adaptation stress response then the body must use up a master hormone called Pregnenolone to then make Cortisol. The more Pregnenolone used up to make Cortisol, the less there is to make other hormones such as Progesterone, estrogen, DHEA, testosterone ect., which then has a cascade effect on mood, energy levels, libido, menstrual issues, fertility, immunity response, youthfulness, weight issues, high cholesterol, diabetes from insulin insufficiency, susceptibility to heart attack, stroke, cancer, osteoporosis and much more.

How to Combat Stress

Moderate exercise,

Increase water to 8 glasses a day,

Avoid creating a build up of serotonin in the body by allowing the serotonin to convert to melatonin at night time by going to bed before 10.00pm and having at least 8 hours rest a night in complete darkness. (See blog on Are you sleeping in the dark?).

Avoid situations that create volatile emotions

Avoid stressful situations that you can avoid like long distance running, sky diving, or driving to work in the city.


Qi Gong, Yoga, deepen your breath

Listen to music.

Go for a walk.

Acupuncture and herbal medicine.

Avoid stressful foods like sugar and caffeine.

Avoid the use of SSRIS (Serotonin reuptake inhibitors). For depression try an everyday   a Hatha yoga or Tai qi class or practice at home. Eat food with Tryptophan, take B vitamin supplement and SAMe.

Reducing the use of electronic equipment which releases positive ions. Also use a negative ionizing machine, which will help balance serotonin levels.  (The Ionizing study)

Correct chemical and hormonal imbalances by a hypoglycemic diet together with an omega-3 fatty acids supplement.

Considering exposure to emotional stress may be  the main cause of symptoms, it is to seek some sort of emotional transformative counseling and or kinesiology.

Observe your addictions, and ask yourself “Why do I crave this, and does this serve me”?

This is THE treatment to restore a person to health.

Mercury and its effects on the Body.

It can be confusing to decide what to do about eating fish and shellfish. Fish and shellfish are rich in omega-3 fatty acids, which is the building block for hormones, including sex hormones. It is important to have Omega 3 in the diet because if your sex hormones become deplete then symptoms like low sex drive, infertility, low mood and energy levels just to name a few, may occur. Omega 3 is also a precursor in making a strain of hormone known as prostaglandin type 3, which reduces inflammatory cursors and thus overall pain in the body. Inflammatory cursors are elevated in arthritic conditions and other painful conditions like long standing period pain and migraines.
Fish is a good source of quality protein and low in saturated fat. Eating fish can contribute to a healthy heart, and is also important in the brain growth and development in children.
Unfortunately, along with the protein and fatty acids, many types of fish and shellfish contain methylmercury. Mercury is a toxic metal with significant effects on the thyroid.  While large doses of mercury can induce hyperthyroidism, smaller amounts can induce hypothyroidism by interfering with both the production of thyroxin (T4) and the conversion of T4 to T3. Mercury disturbs the metabolism of copper and zinc which are two minerals critical to thyroid function.  Gray hair can be an indication of mercury accumulation, more so in females than males.
Mercury causes disruptions to the immune system functioning and promotes the production of IgG and IgE autoantibodies which also are involved in autoimmune thyroid disease and inflammatory conditions.
Mercury has a very long half-life in the body and has been found in cancerous tissues.
It also has a negative impact on the brain and nervous system, specifically affecting memory, attention span, cognitive thinking skills, language development and visual and fine motor skills especially in children. This is seen particularly in babies who were exposed to methylmercury in the womb through their mother's eating of fish and shellfish during pregnancy.
Methylmercury can build up in your body. This means that even if you aren't pregnant now, methylmercury buildup from overconsumption of fish could still be present if you become pregnant up to a year later. For this reason, any woman who plans to become pregnant in the future should try to follow the same recommendations as those who are pregnant or nursing.

* These fish are endangered due to overfishing   ** Farmed salmon contains higher levels of PCBs (in  the fat portion)
*** Fish are high in purines – not recommended for gout sufferers

Where has the fish been farmed?
Look or ask where the fish has been farmed or what part of the worlds ocean has the fish has been pulled from. Buying fish from Australia and New Zealand is always safer than parts of Asia and South America where Mercury levels in the water are higher.

Amalgam Fillings and Mercury
There is ample evidence that mercury leaches from dental amalgam fillings and contributes to thyroid disease and anemia.  If you have any amalgam fillings in your teeth the mercury is known to leak into the body after many years.  It is advisable to pull out amalgam fillings at least a year before you fall pregnant. If you have many fillings then you should pull them out one at a time, as it has been found that pulling the filling out also releases Mercury. So as to not overload the body with mercury toxicity during the removal, do not get them removed all at once.

Perhaps the negative effects we see from vaccines are at least partially the result of toxic metals. The association of autism with vaccinations may be related to mercury toxicity. Please think about how many vaccines you administer to your child at one time, as there are studies showing sudden autistic behavior after a large vaccination course administered in close succession.

Contact Lens Solution
Thimerosal is the mercury-containing preservative that was used in contact lens solutions. Hopefully there are no more of these solutions on the market but if you use contact lens solutions check the label.

How do I clear Mercury from my Body?
Milk and quite likely estrogen cause an increase in the absorption of mercury., so removing dairy or reducing dairy consumption may help. Also, doing a hormonal test to see if your estrogen levels are in a good range and not elevated is also advisable. Elevated estrogen levels, also known as estrogen dominance is quite common these days with so many xeno-estrogens in our foods, food containers, and with the use of hormonal contraceptives.
Selenium is the key mineral which protects the body from mercury toxicity.  One study showed that cilantro (Chinese parsley) helps remove mercury from the body and protects the body from pre-cancerous lesions. Also, Zeolites can remove heavy metal toxicity from the body if taken consistently for a few months.
