One-hour cell phone exposure at typical SAR levels showed no immediate effect on melatonin production in this small study.

Plain English Summary

Summary written for general audiences

Researchers exposed 9 healthy young men to cell phone radiation for one hour while measuring melatonin levels through urine tests. Melatonin is a hormone that regulates sleep and circadian rhythms. The study found no significant changes in melatonin production after exposure to 900 MHz radiation at 1.23 W/kg SAR, suggesting that typical cell phone use may not disrupt sleep hormones.

Study Details

The present study sought to evaluate possible effect of the exposure to EMF emitted by cellular phone on 6-hydroxymelatonin sulfate (6-OHMS) excretion, which reflects melatonin levels in blood.

The examined group consisted of 9 healthy males aged 19-29 years. The experiment was performed under...

Mean 6-OHMS level in both experiments did not differ significantly for any of the respective time po...

The results of our investigation has demonstrated that EMF emitted by cellular phones has no distinct influence on the melatonin level.
