What is the impact of electromagnetic waves on epileptic seizures?
This study is more applicable to cellular and wifi given the frequencies used but it does show EM waves can trigger seizures. It could also be applicable to autonomous technologies depending on the frequencies used. A counterpoint is they are exploring using EM radiation to help stop seizures. Its possible that EM radiation can have a dual effect resulting in both positive and negative health consequences.
However what may throw tests off is the nature of solar and geomagnetic activity during such tests as both of these are believed to trigger the same sorts of complications. There is little we can do to stop this but we can reduce our man-made radiation source exposure by, among other things, not acquiring an EV or ICE loaded with electronics and minimize our use of cellular and wifi. Sadly these last two are near impossible with the younger generations. Could be part of the reason why Gen Alpha is so "feral".
