Plain English Summary
Chinese researchers exposed mouse reproductive cells to radiation from a commercial mobile phone in different modes (standby, listening, dialed, and dialing) and measured DNA damage. They found significant DNA damage in listen, dialed, and dialing modes, with the highest damage occurring during dialing and dialed modes when radiation intensity is greatest. The protective hormone melatonin was able to reduce this DNA damage, suggesting potential ways to protect reproductive health.
Why This Matters
This study reveals a critical finding that many people overlook: your phone continues emitting radiation even when you're not actively talking on it. The research demonstrates that DNA damage in reproductive cells occurs not just during calls, but also in dialed and dialing modes when your phone is connecting or maintaining a connection. What makes this particularly concerning is that the 'dialed' mode is technically part of standby operation, meaning your phone poses a reproductive health risk even when you think it's inactive. The finding that melatonin can protect against this damage offers hope, but the real takeaway is distance. The researchers' recommendation is straightforward: keep your phone away from your body at all times, not just during conversations. This challenges the common assumption that phones are safe when not in active use.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 20 min in standby, listen, dialed or dialing modes for 24 h

These results regarding mode-dependent DNA damage have important implications for the safety of inappropriate mobile phone use by males of reproductive age and also suggest a simple preventive measure: Keeping mobile phones as far away from our body as possible, not only during conversations but during ‘dialed’ and ‘dialing’ operation modes. Since the ‘dialed’ mode is actually part of the standby mode, mobile phones should be kept at a safe distance from our body even during standby operation. Furthermore, the protective role of melatonin suggests that it may be a promising pharmacological candidate for preventing mobile phone use-related reproductive impairments.
