Neurologists dismiss claims suggesting in-flight entertainment screens emit EMF
Neurologists refute the idea that wearing a cap on a flight can protect against EMF exposure from screens. They clarify that the regulated levels of EMF pose no harm and that post-flight fatigue is caused by dehydration and jet lag, not EMF. EMF-blocking hats have no proven medical benefit and simple habits like staying hydrated are more effective in preventing fatigue and headaches.
