Talking on cell phones for over an hour daily significantly reduces protective antioxidants in saliva compared to minimal use.

Plain English Summary

Summary written for general audiences

Researchers studied how cell phone talk time affects the antioxidant levels in saliva from 105 volunteers. They found that people who talked on their phones for more than an hour daily had significantly lower antioxidant capacity in their saliva compared to those who talked for less than 20 minutes. This matters because antioxidants help protect our cells from damage, and the salivary glands sit right next to the phone during calls.

Why This Matters

This study adds to growing evidence that cell phone radiation creates oxidative stress in human tissues. The science demonstrates that even routine phone use - something as simple as talking for over an hour daily - measurably reduces the body's natural antioxidant defenses in the salivary glands. What makes this particularly concerning is that these glands receive direct exposure during phone calls, positioned right against the device. The reality is that most people today far exceed an hour of daily phone use when you factor in calls, streaming, and other activities. While the wireless industry continues to focus narrowly on heating effects, independent research like this reveals that biological impacts occur at exposure levels we encounter every day. You don't have to eliminate your phone, but this research supports simple precautions like using speakerphone or earbuds to create distance between the device and your head.

Exposure Information

Specific exposure levels were not quantified in this study.
