ABSTRACT
This chapter tries to ascertain whether mobile phones (and mobile phone-like exposures) impact on health, with the premise being that, if they do, then this would not only illuminate a hidden danger, but also necessitate a search for a new biophysical mechanism. Electromagnetic energy travels as waves, which, depending on the particular frequency, can interact with the body in different ways. Health effects from the low-level exposures from mobile phones are not predicted because the resultant heating is too low. The body engages in a tightly regulated cycle of physiological changes that induce and promote effective sleep. These can be measured in terms of indices of sleep architecture, such as sleep duration, and the underlying electroencephalograph (EEG) changes that accompany these stages. The EEG power spectrum can be resolved into relatively discrete frequency bands, which represent the sum of a range of distinct cognitive processes.
