Research on subjective symptoms and mobile telephony

In summary, the published laboratory research, to date, on electromagnetic hypersensitivity and subjective symptoms from exposures to cell-phone RF fields are very limited. One study suffered from a single-blind design, and the exposure conditions were not randomized. The other was a carefully executed, double-blind study with randomized exposures. The statistical strength was weakened by a small number of subjects in the study. Nevertheless, the evidence now available suggests that, while the reported hypersensitivity and subjective symptoms may be real, the question whether they are associated with cell-phone use must await more comprehensive studies.
