How things have changed (us):
Many of today's acute and chronic illnesses have been ascribed to damage to the environment: chemical proliferation; fertilizer abuse; over reliance on antibiotics; plastics in landfills; hormones in dairy industry; poor enforcement of industry by the Environmental Protection Agency, and many more. Plenty of people have developed symptoms related to toxins in the environment: mercury, lead and other heavy metals, for example. Exposure to these items can come from a number of sources. Besides being responsible for these changes to our environment, more concern should also be directed at how society has changed.
When Traditional Chinese Medicine, Auyurvedic Medicine, and even Homeopathy were developed, life's daily rituals, work and leisure were guided by a very different "master" than they are today. There was no electricity. People woke up with the sun and retired with the sun. Even after Thomas Edison permitted us to alter those patterns of waking and sleeping, eventually allowing industry and manufacturing to employ hundreds of thousands of people on 2nd and 3rd "shifts", most people still slept with the sun.
Each decade in the 20th century brought more changes in leisure habits, financial debt and work habits. The work week lengthened and the number of hours spent on home work increased steadily. While the amount of hours spent sleeping started to decline several decades ago, the actual number of hours spent doing something increased. Late night television, e-mailing, surfing the web, blogging and more keep people fully occupied with little or no down time for the nervous system (or any system).
The consequence of this has been, in my opinion, a rise in the incidence of allergy across society. Allergies are much more common today than 50 years ago, and so are a host of other allergy related illnesses, including autism.
The effect of these allergic overloads is played out on the meridian system. TCM and Auyervedic approaches are not going to have permanent effects on the energy systems of the body because they do not regularly stop the effect of the allergies. TCM, et al, were not concieved of in a time when allergies were as rampant as they are today. Thus, our lifestyle and other influences pose a burden to the meridian system that is truly extraordinary.
Turning off the allergies through NAET can restore the meridian system to its normal devices of balance, and equilibrium is much easier to achieve through TCM and other approaches.
NAET has become a very relevant tool to help us in a time of significant stress.
