Results (acc. to author)

40 respondents described symptoms such as unpleasant warmth or a dull ache in the head, mostly occurring minutes after beginning a call. The symptoms did not occur when using an ordinary handset, and were different from ordinary headaches. 75 % of the cases were associated with digital mobile phones. Three respondents reported local symptoms associated with wearing their mobile phone on their belts.
The author concluded that further work is needed to determine the range of symptoms and their mechanisms.
