Three hours of cell phone-like EMF exposure before bedtime showed no detectable sleep disruption in this small study.

Plain English Summary

Summary written for general audiences

Japanese researchers exposed 19 volunteers to cell phone-like electromagnetic fields for 3 hours before bedtime to see if it affected their sleep quality. They found no significant differences in how well people slept, how they felt the next morning, or their brain wave patterns during sleep compared to fake exposure. This suggests that 3-hour EMF exposure from mobile phone technology doesn't detectably disrupt normal sleep.

Study Details

In this study, we investigated subjective and objective effects of mobile phones using a Wideband Code Division Multiple Access (W‐CDMA)‐like system on human sleep.

Subjects were 19 volunteers. Real or sham electromagnetic field (EMF) exposures for 3 h were perform...

No significant differences were observed between the two conditions in subjective feelings. Sleep pa...

We conclude that continuous wave EMF exposure for 3 h from a W‐CDMA‐like system has no detectable effects on human sleep.
