Neurologists dismiss claims suggesting in-flight entertainment screens emit EMF

Neurologists strongly quash the claim that wearing a cap is necessary to protect against EMF (electromagnetic field) radiation from aircraft seat screens, calling the idea scaremongering. Experts like Dr. Sudhir Kumar assert that airplane entertainment screens emit very low-power radiofrequency signals, similar to or less than a mobile phone on standby, and are regulated to be far below international safety limits (FCC, ICNIRP). There is no scientific evidence that these low levels of EMF cause neurological damage, brain inflammation, or fatigue. Instead, the real causes of post-flight fatigue are well-established factors like low cabin humidity (dehydration), mild hypoxia (lower oxygen), sleep disruption, long sitting, and jet lag, none of which are related to EMF. The neurologists conclude that EMF-blocking hats have no proven medical benefit and that any perceived improvement is likely a placebo effect. To truly combat post-flight fatigue, passengers should focus on practical habits like hydrating well, avoiding heavy meals and alcohol, adjusting sleep schedules, and moving/stretching regularly during the flight.
