A previously healthy 8-year-old boy suffered “severe” headaches when attending a school just 200 meters from a 5G cell tower, according to a new peer-reviewed case study.

The study, published in the Annals of Clinical Case Studies, reported that the Swedish boy — who had no prior history of headaches — also experienced dizziness and fatigue.

The symptoms stopped when the child started wearing a radiofrequency (RF) radiation-blocking cap, jacket and scarf to school.

The report also noted the boy didn’t have the symptoms at home where levels of RF radiation were much lower.

The findings suggest the high levels of RF radiation at school caused the boy’s symptoms, the researchers concluded.
