🧠 5 KEY TAKEAWAYS
• Not all EMFs are the same — ionizing and non-ionizing radiation impact the body differently, but both can disrupt cells.
• Bluetooth headphones may emit low radiation, but even 0.1 watts can affect the frontal lobe.
• Air tube headphones offer EMF-free audio by converting electrical signals into acoustic sound away from your head.
• Common sources of exposure include phones, routers, laptops, and wearables — distance and duration matter most.
• Simple practices like using Faraday pouches, ethernet, and grounding blankets can reduce daily EMF load.
