Electrical EMF Radiation Health Risks – Alzheimer’s and Parkinson’s Disease
A few studies concentrated on the effects of electrical (“power frequency”) electromagnetic fields (EMFs) on the human brain function and nervous system (Savitz et al., 1998; Hakansson et al., 2003, Feychting et al., 2003; Qiu et al., 2004). These studies clearly established that there is a strong and consistent relationship between exposure to electrical EMFs and various types of neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, motor neuron disease and amyotrophic lateral sclerosis (ALS) or Lou Gehrig’s disease. ALS is also a type of motor neuron disease. The studies of Savitz, Hakansson and Feychting furnish ample evidence on the relationship between electrical EMF exposure and Alzheimer’s disease, while the study by Hakansson proves the relationship between exposure of electrical EMFs and ALS. Various other studies had also confirmed the link between electrical EMF exposure and ALS and Alzheimer’s disease (Johansen, 2000, 2001, 2004; Ahlbom, 2001; Park et al., 2005).
The studies focused on the death of certain neurons in the brain, leading to the above-mentioned neurodegenerative diseases. The major risk factor in Alzheimer’s disease is the presence of amyloid beta in high levels. electrical EMF exposure had been found to increase the level of amyloid beta in the brain significantly, thus elevating the risk of Alzheimer’s disease. Melatonin protects the brain against any neuron damage, thus reducing the risk of Alzheimer’s disease. Since exposure to electrical EMFs reduce melatonin levels, increased risk of Alzheimer’s disease results. A recent meta-analysis that comprised of 14 epidemiological studies confirmed the relationship between occupational electrical EMF and Alzheimer’s disease (Garcia, 2008). The risk in the development of Alzheimer’s disease and other types of dementia was higher in people living near power lines, a study revealed (Huss, 2008). According to the study, the longer the exposure to electrical EMFs, the higher the risks increase for dementia.
Moreover, long-term exposure to electrical EMFs have been found to alter the levels of calcium (Ca2+) in neurons and also induce oxidative stress. Similarly prolonged exposure to electrical EMFs can stimulate neurons in synchronous firing, resulting in toxin build-up and damage to the neurons, particularly to the large motor neurons.
Electrical EMF Radiation Protection – All Homes and Workplaces Should Be Tested
Most homes and workplaces will have electrical EMF radiation hot spots that can easily exceed the exposure levels known to impact on you and your family’s health eg. near electrical devices, power meter boxes, wiring behind walls etc. EMF Safe recommends all homes and workplaces be tested for all electrical and wireless EMF radiation exposures. Often simple changes can be made to reduce or avoid elevated exposures when they are found. EMF Safe rents EMF Detection Kits nationwide that are excellent for this purpose and come with easy to follow instructions including safety reference levels.
