Plain English Summary
German researchers exposed rats and hamsters to 900 MHz radio frequency fields (similar to early cell phones) for up to 6 hours to see if it would affect their pineal glands, which produce the sleep hormone melatonin. They found no changes in melatonin production or pineal gland structure at any exposure level tested. This suggests that short-term RF exposure at these levels doesn't disrupt the body's natural sleep-wake cycle regulation.
