Can radio frequencies cause headaches

High frequency sound causes two types of health effects: on the one hand objective health effects such as hearing loss (in case of protracted exposure) and on the other hand subjective effects which may already occur after a few minutes: headache, tinnitus, fatigue, dizziness and nausea .

The WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.

Radio waves from a cell phone can affect the metabolism of a person’s brain , according to a study in the Journal of the American Medical Association. But the effect has nothing to do with cancer, and researchers say there’s no evidence that the increase in metabolism is harmful.
