Another cell phone study, this one out of Turku, Finland, has revealed that cell phone use does, in fact, affect the brain. A significant finding amid the controversy surrounding the extremely popular devices.
PET measurements were taken on 13 young, healthy males who were exposed to the GSM signal for 33 minutes each, explained Science Daily. The study confirmed that glucose metabolism in the temporoparietal and anterior temporal areas of the brain hemisphere closest to the device’s antenna becomes suppressed by GSM mobile telephone electromagenetic fields, said Science Daily.
The study, initiated by Centre for Cognitive Neuroscience (CCN) at University of Turku, was described as methodologically unique in that it used both proficiency in brain imaging via the National PET-Center and CCN; measurements and modeling of radiation via the Radiation and Nuclear Safety Authority in Finland, STUK; and measurements of skin temperature taken by the Finnish Institute of Occupational Health, TTL, noted Science Daily.
And, while definitive health risk conclusions could not be made, the study does indicate another way in which cell phones affect the brain. Study results appear in the Journal of Cerebral Blood Flow & Metabolism.
Recently, writing that the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) classified cell phone radiation as potentially carcinogenic to humans based on its review of hundreds of human and animal studies, including the the well-known 2010 INTERPHONE study. That study revealed that the heaviest cell phone users—those using a device for at least 30 minutes daily—experienced a 40 percent increased risk for gliomas, the most commonly diagnosed type of brain tumor. About 13,000 people from around the world were involved in the Interphone Study.
While much research on cell phone radiation effects has not been conclusive, experts generally agree that more research is needed. Especially given that newer research has found links between the devices and other adverse reactions, such as decreased sperm quality and motility and male fertility.
