A recently published Chinese study has now found strong evidence linking cell phone radiation to headaches in children and adults. This 2017 study, which carried out a systematic review of some 2699 previous studies going back to 1990, also found a dose-response relationship between the risk of having a headache and duration of cell calls and frequency.
A 2016 Korean study examined a number of variables, stress, sleep, cognitive function, and depression, but found that cell phone call duration to be the main determinant of the severity of headaches.
A major Danish study on some 52, 000 children enrolled pregnant women had similar findings. Then when their children reached the age of seven, the mothers completed a questionnaire regarding their child’s health. It was found that children with cell phone exposure had higher odds of headache-related symptoms than children with no exposure.
In 2003, TNO Physics and Electronics Laboratory published the results of a study commissioned by three Dutch ministries on cell towers. (4,5) found that cell phone radiation can cause headaches and nausea. It also found a link with other symptoms such as dizziness fatigue, weakness, and muscle pain – despite a lower dose of radiation than that of cell phones being used in the study.
