Can you hear me now? For years, it has been popular doctrine that cell phone use is bad for our brains, but we glue our phones to our ears anyway. Cell phones emit radio frequency-modulated electromagnetic fields (RF-EMFs) that are questioned for their potential danger when the brain is exposed to them. The oscillatory frequencies of RF-EMFs correspond to those measured in neural tissue, and thus could interfere with neural activity. The amount of electromagnetic radiation given off by our communication devices is small, but is radiation all the same. Radiation exposure is dangerous for any kind of cell in our body, and can penetrate cells and damage DNA either by crashing into the molecule directly or causing damage indirectly by forming free radicals from water that can have cancer-causing effects.
