Some of the commonly reported changes that people have reported as a result of having had the Jennetics® adjustment have been: Feeling calmer, sleeping better, feeling a profound tiredness when the compulsion of feeling “driven” stops, small incidents that used to drive a person to exaggerated anger now no longer has any affect, can now know what it is like to be relaxed, relaxation of constantly held muscle tightness, a beautiful feeling of well being, just feeling better all over.
Much could be said about stress and the way it changes the way the body works. Often there are specific questions that need to be asked as well as answered.
How do we know the brain changes?
We do this by studying the changes in the ability of the eyes to change vision. The eyes are a part of the brain. There is a lot of brain circuitry devoted to vision.(6) There are even more than this when we look to the interactions between balance and hearing and vision as well as alterations of physical functions such as regulation of blood flow and alteration in focal length and regulation of light input to the retina, depth perception etc. How we see and how our eyes work is based on how the brain works. For an easy but more complete explanation of blind spots see reference (5) below
Blind spot mapping
We all have a blind spot in each eye. The blind spot represents a part of the eye where the optic nerve joins the eye ball itself to the brain. In this portion of the eye there is no retina. So you can't see at this "spot". All of the neurological circuitry to do with vision is considered to be contained in the head (eyes, optic nerves and the optic areas of the occipital cortex).
This view is quite correct. What we now
know is that by working on body at large, functional changes in the brain
can induced. This is not a new notion as body movement has been used to
improve learning and memory. (8), (9)
In an ideal state, the blind spot should be as small as possible. That way we have a more complete view of the world around us. By mapping (measuring) the blind spots, we can assess the functioning of the brain circuitry related to vision. Blind spots are never perfectly symmetrical since we all have some variation between our left and right sides. The same is true of our eye sight as well.
What we have done to show that the brain really changes is:
Blind Spot - before Blind Spot - after

Note the more even size of the blind spots in the "after" test . In fact both sides have improved and the symmetry became just about perfect. The person involved in this test had had previous Jennetics adjustments but not for some months. In the interval since the last Jennetics adjustment her stress index had risen significantly. Under those circumstances, just one adjustment was enough to "normalise" the blind spots. For a person with a higher stress index or no previous Jennetics adjustments, more adjustments would likely be need to achieve similar results. Changes such as these are quite thrilling to see as they validate what we see clinically in changes related to brain function.
Ask to have your Stress Index assessed (next time you are in for a check up).

"It's not stress that kills us, it is our reaction to it."
- Hans Selye
Label reading at the grocery store and daily exercise have become the standard for a health conscious society seeking a higher quality lifestyle. However, lack of mental and emotional self-management is a root cause of most stress-related health problems. Physical health can be improved through a balanced approach to exercise and diet but without managing how we respond mentally and emotionally to day-to-day events, stress accumulates and can substantially damage a person’s system." (1)
"Stress is a greatly misunderstood term." So says Professor Bruce McEwen of Rockefeller University in New York City, in an interview with the ABC’s Dr Norman Swan.(1)
Let us see what he has to say about stress.
Prof Bruce McEwen: “… they will not think about stress in the same way as before, because ‘stress’ is a term that is over-used and I think misunderstood because of its ambiguity, and what we’re trying to present is a notion of how the body attempts to adapt in the face of stress, but at the same time, if the same system that protects us is over-used, it results in wear and tear that can cause damage, and this we call allostasis, and allostatic load.
Dr Norman Swan: “Allostasis is essentially this balance - that stress is often thought of as all
bad, and your argument is, as is the argument of others, that there are good and bad things about
stress. In other words, we need stress to survive, and it’s just when the balance is out that things
Prof Bruce McEwen: "That’s right. I think life would be pretty dull if we didn’t have stress or
challenges in our life. I sort of like to use the more neutral word ‘challenge’, and our bodies are
designed to help us meet a challenge, meet changing environments; something happens, we react
to it. We learn something from it; if we’re injured in the classic fight or flight response: an antelope
running away from a predator - if the animal is injured and still survives, then, as we discovered a
number of years ago, immune function is actually enhanced by the stress response and this helps
the animal fight the infection and repair the wound. In the same sense, the stress hormones help
the animal remember a place to avoid in the future, to stay out of trouble, so it actually helps
memory function. It helps a lot of things that help us to adapt. At the same time, the system when it’s over-used, or not properly turned off, over a long period of time can create a wear and tear on the body which we call allostatic load.” [emphasis added]
The brain’s response to allostatic load is what we seek to correct when using the chiropractic technique called Jennetics®.
In my experience it is the “not properly turned off” stress responses of the body that add to what is called the “Stress Index”. The Stress Index is an indirect measure of the brain’s stress mode activity level. The way it seems to work is that when we get stressed, our body under the direction of the Nervous System switches into a stress mode to enable us to cope with the things that stresses us. The problem seems to be that when the stressing event is resolved, at some point the nervous system decides that it is better, or more efficient to stay in stress mode of behaviour just a bit. After all it has experienced increased levels of stress, so it may as well just be ready for stress when the next bit of bad stress comes along. That "bit" is most often below the threshold of what we consciously recognise.
As the next stress arrives we now get a slightly exaggerated, stronger response to the new
stressing event and with this seems to come a response that makes the body switch imperceptibly just that little bit further into stress mode of brain organisation. This process accumulates, "habituates", as life progresses, culminating in a Stress Index that can be measured.
Prof Bruce McEwen continues: “Stress as I think of it, has of course two [components]. We often call them good stress and bad stress. The bad stress is something that I prefer to call "stressed out", which I think means the bad stress being in a state of anxiety, frustration, perhaps anger, feeling fatigued, overworked, you name it. This is a reflection of a prolonged or chronic state, which is most certainly accompanied by elevated levels of allostatic load.
…….. Well, the fact that if you become stressed out, you’re gong to lose sleep at night, your
physiology is going to respond. For example, we know that if you lose sleep at night, your cortisol
goes up, your glucose goes up. Some of these allostatic load measures are elevated and you can
very quickly overcome it if you begin to get good sleep. Many people go through life with less than
perhaps optimal levels of sleep, and are probably suffering from a chronic state of sleep
deprivation, which among other things, can make them hungrier, so they’re going to eat more of
what we call comfort foods, which is going to load their bodies with calories, and the whole thing
feeds forward on itself. People who are stressed out are often going to neglect good lifestyle
practices. They may smoke, they may drink more than normal, they may eat more than normal and
they may neglect regular exercise. So stress or being stressed out has an effect on lifestyle
patterns that in turn add to the allostatic load.”
Stress seems to not end with the conclusion of early childhood incidents. The effects of these can also linger and have an effect on health in later years. (7) This is a common thread that can be found through probing for those "painful" incidents that we all seem to experience from our elders or even our peers. See also NET and EFT as these can help with emotional issues.
Stress is known to detrimentally influence the immune system and is implicated in the body's ability to activate natural killer cells. Stress is also implicated in 75% of Alzheimers patients. Repeated stressful events also contribute to this effect.11
"The consecutive stages of the multistep immune reactions are either inhibited or enhanced as a result of previous or parallel stress experiences, depending on the type and intensity of the stressor and on the animal species, strain, sex, or age. In general, both stressors and depression are associated with the decreased cytotoxic T-cell and natural-killer-cell activities that affect processes such as immune surveillance of tumours, and with the events that modulate development and accumulation of somatic mutations and genomic instability." (10)
So the greater the stress intensity, the greater the number of events and has implications not only for our responses to infection defence but also to the body's response to cancer.
