  "map_content": "What RF from Bluetooth can and can\u2019t do\n- Power and exposure: Bluetooth operates around 2.4 GHz at very low power (typically 1\u201310 mW; some up to ~100 mW). That\u2019s orders of magnitude lower than a mobile phone next to your head (often 100\u20131000 mW when transmitting). Exposure from Bluetooth is well below international safety guidelines (e.g., ICNIRP 2020) that are set with large safety margins.\n- Cancer/long\u2011term health: Large animal studies (e.g., the US NTP 2018) found some tumor signals at extremely high, whole\u2011body exposures far above what people get from phones\u2014let alone Bluetooth. Regulatory and public health bodies (WHO, FDA, ICNIRP, ARPANSA, Health Canada) conclude that current evidence does not show health harms from low\u2011level RF within limits. Bluetooth falls in that low\u2011level category.\n- \u201cElectromagnetic hypersensitivity\u201d: Dozens of double\u2011blind provocation studies (e.g., Rubin et al.) consistently find that symptoms reported by sensitive individuals do not track whether RF is actually on or off\u2014pointing to a real symptom experience but not caused by RF itself (a nocebo effect likely plays a role).\n- Brain function/sleep EEG: A few small lab studies with phone\u2011like signals (not Bluetooth) reported subtle, short\u2011lived changes in EEG spectral power during or after exposure, but without clear, consistent effects on sleep quality or cognition. Findings are mixed and not considered clinically meaningful, and exposures were higher than Bluetooth.",
