I had heard that it could have side effects esp when wires are exposed
here is an excerpt from a study for you -
For many years, scientists have suspected that long-term exposure to extremely-low-frequency electromagnetic fields (EMFs) may be associated with increased risk of neurodegenerative diseases such as Alzheimer disease, Parkinson disease, and amyotrophic lateral sclerosis. Some studies have shown that EMF exposure can damage DNA in a variety of human and animal cells, while others have shown no significant effect. Now Henry Lai and Narendra P. Singh of the University of Washington offer support for speculation that environmental exposure to EMFs is hazardous and that the effects may be cumulative [EHP 112:687-694]. They also offer a potential cellular mechanism for cell damage associated with EMF exposure that may help explain anomalies reported earlier in the literature.
Lai and Singh's findings support the so-called free radical hypothesis, which posits that extremely-low-frequency EMFs increase free radical activity in cells, thereby causing DNA damage and disturbing other cellular processes and functions. They and others had shown earlier that free radical damage can lead to cellular necrosis and apoptosis. Such effects are particularly troubling in neurons, because these cells cannot divide and are not replaced when they die--thus the potential link to neurodegenerative diseases.
there are numersous other studies showing the same thing
I hope that's what you were looking for
