Plain English Summary
Chinese researchers compared 81 cell phone users to 63 non-users from corporate settings, measuring their reaction times and other brain function tests. They found that cell phone users had significantly slower reaction times, and the longer someone had been using a phone, the worse their performance became. This suggests that regular cell phone use may impair basic brain functions like processing speed and coordination.
Why This Matters
This early study from China provides important evidence that cell phone radiation affects fundamental brain processes. The finding that reaction time slowed in proportion to usage duration suggests a dose-response relationship - the hallmark of a genuine biological effect rather than coincidence. What makes this research particularly relevant is that it measured real-world exposure patterns rather than artificial laboratory conditions. The neurobehavioral tests used here assess the same cognitive functions you rely on for driving, work performance, and daily decision-making. While this study lacks specific radiation measurements, it demonstrates measurable impairment in cell phone users compared to non-users in the same work environments, controlling for other lifestyle factors.
Exposure Information
Specific exposure levels were not quantified in this study.
