Both natural and artificial extremely low frequency (ELF) electromagnetic fields (EMF) are reportedly found to be biologically active.
Exposure effects of high frequency and high intensity EMFs especially from microwave devices and mobile phones are popularly
discussed and researched as compared to exposure effects of ELF EMFs. Increased use of electricity during previous decades is
causing greater or forced exposure to ELF EMFs. Exposure assessment of ELF EMFs in terms of health effects has proved to be a new
area of research. The present study deals with effects of ELF EMFs on brain activity, electrophysiological signals and anxiety related
issues. Previous efforts in this regards are identified and explored to illustra te the effects. The new areas of research are identified
which can be extremely interesting for medical, bioelectromanetics and electrical engineering streams.
