Cell phone radiation at typical use levels actually increased melatonin production in this study, challenging assumptions about EMF sleep disruption.

Plain English Summary

Summary written for general audiences

Researchers exposed isolated hamster pineal glands (which produce melatonin, the sleep hormone) to cell phone radiation at 1800 MHz for 7 hours at various power levels. Surprisingly, they found that moderate exposure levels actually increased melatonin production, while only the highest level (which caused tissue heating) suppressed it. This challenges the widely-discussed theory that cell phone radiation disrupts sleep by reducing melatonin.
