...and nor do they cause worse headaches in "sensitive" people

People who report being sensitive to mobile phone signals cannot detect such signals and are no more likely to have worse headaches than people who are not sensitive. Rubin and colleagues (p 886) conducted a double blind, randomised study in which 120 participants were each exposed to three "conditions": a 900 MHz GSM mobile phone signal, a non-pulsing signal, and a sham condition (no signal). Headache severity increased during exposure and decreased immediately afterwards for both sensitive and non-sensitive people. But no significant differences in severity of headaches were found for the three exposure conditions, or between the sensitive and non-sensitive groups. The authors suggest that self reported sensitivity to mobile phone signals may be primarily psychological.
