Cell phone use has become almost essential to daily life, for both business and personal use. Although no link between brain cancer and cell phone use has yet been proved, researchers have warned cell users for years of the potential health concerns of the units’ electromagnetic waves. New research into cell phone use suggests that people should keep their cell phones as far as possible from their bodies. Wearing a cell phone on a clip or holster close to the hip could reduce bone density in an area of the pelvis commonly used for bone grafts. Investigators of the new study, which was conducted in Turkey, used dual X-ray absorptiometry to measure bone density at the upper rims of the pelvis in 150 men who carried cell phones on their belts. The study noted that participants carried their phones for an average of 15 hours a day, and had used cell phones for an average of six years. Bone density was slightly reduced on the side of the pelvis where the men carried their cell phones, the study noted. Still, the researchers say that the difference wasn’t statistically significant, and didn’t approach bone level density reductions seen in individuals diagnosed with osteoporosis. However, the participants were relatively young (with an average age of 32), and the results suggest that further bone weakening may occur. The study, which was published in the September issue of the Journal of Craniofacial Surgery, concluded that electromagnetic fields emitted by cell phones may have a harmful effect on bone density. Newer cell phones may reduce users’ exposure to electromagnetic fields, but in the meantime, researchers say it would be best if people kept their cell phones at a safe distance as much as possible. – Anthony Isaac Palacios
