View Original AbstractCell phone radiation at safety limits didn't disrupt sleep in healthy young men, but real-world intermittent exposure patterns weren't tested.
Plain English Summary
German researchers exposed 30 young men to cell phone radiation at maximum power levels (2 W/kg SAR) for 8 hours nightly while they slept, testing both older GSM and newer 3G signals. They found no meaningful effects on sleep quality or architecture across multiple measured variables. The study suggests that cell phone radiation at current safety limits doesn't disrupt normal sleep patterns.
Study Details
In the present double‐blind, randomized, sham‐controlled cross‐over study, possible effects of electromagnetic fields emitted by Global System for Mobile Communications (GSM) 900 and Wideband Code‐Division Multiple Access (WCDMA)/Universal Mobile Telecommunications System (UMTS) cell‐phones on the macrostructure of sleep were investigated in a laboratory environment
An adaptation night, which served as screening night for sleep disorders and as an adjustment night ...
Thirteen of 177 variables characterizing the initiation and maintenance of sleep in the GSM 900 and ...
From the present results there is no evidence for a sleep-disturbing effect of GSM 900 and WCDMA exposure.
