A double-blind, randomised, placebo-controlled, crossover pilot study\"\n...\n\"Materials and methods\nStudy design\nRadiofrequency device, exposure set-up, and power dosimetry\nThe study involved a randomised, double-blind, placebo-controlled, crossover design over 4 weeks on healthy adults at their homes in Melbourne, Australia. We compared 7 consecutive all-night exposure to either an active or inactive (sham) pulse-modulated radiofrequency device. The device used was a commercially available Uniden baby monitor (BW 3001 model), consisting of a digital wireless monitor and digital wireless camera with two-way walkie talkie capability. This device has a transmitting power of 15 dBm and employs a frequency range of 2.4 to 2.4835 GHz using a frequency-hopping spread spectrum system (FHSS) with Gaussian Frequency Shift Keying (GFSK) modulation to avoid interference. The units were tested prior to randomisation to determine the level of radiation emitted. This was done by placing them two metres apart and using a Gigahertz HF59B Analyser with UBB27 omnidirectional antenna (frequency range between 27 MHz to 3.3 GHz) and a Gigahertz HFW59D Analyser with UBB2410 omnidirectional antenna (frequency range between 2.4 GHz and 10 GHz). The metres were set at Peak and Peak Hold to establish the minimum and maximum levels over the course of 1 h, which were determined to be between 2.2 and 7 mW/m2. This is well within the International Commission for Non-Ionising Radiation Protection public guidelines of 10 W/m2 for frequencies above 2 GHz within the far field zone averaged over 30 min and the whole body (37).\"\n...\n\"Results\nWhile the goal was to recruit 20 participants, due to the strict inclusion criteria and impact of the pandemic, data from only 12 participants were evaluated. Summary statistics for the primary and secondary outcome measures are outlined in Table 1. Sleep quality as indicated by the PIRS-20 was found to be significantly reduced during RF-EMF exposure compared to placebo exposure (p < 0.05) as illustrated in Figure 2. Three participants (27.3%) scored above the cut off of 20 (out of a total score of 60 for PIRS-20) for risk of clinical insomnia. The raw single-channel EEG signal derived from the Z-machine was converted to EDF format and analysed using Curry 7 EEG analysis software (Compumedics Pty Ltd). The EEG signal was high/low pass filtered (.3 Hz/70 Hz) with a 50 Hz notch filter. Compared to sham-exposure, during the RF-EMF exposure, a statistically significant increase (p < 0.5) in EEG power density in the higher frequencies (theta, beta and gamma bands) was detected during Non-Rapid Eye Movement (NREM) sleep but not in Rapid Eye Movement (REM) sleep. No differences were observed in HRV or actigraphy. When asked, only 44% correctly identified the week with the active intervention.\"","attachments":[],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-6675","tags":["sleep-cognition","exposure-places","policy-standards","research-evidence"],"source_hash":"87cf4b5558da35390f5eee879237f2e773a5eb8c3a0a7f107da547ec0618c083","slug":"sleep-cognition-comment-6675","classification":{"id":"HHS-OASH-2026-0397-6675","body_sha256":"0efb6565f0bcb9fed13062ff5cf31cb3553dc9b67bf9863b52f9def4ca05a48c","status":"ai_reviewed","primary_topic":"neurological","topics":[{"id":"neurological","evidence":"Sleep quality as indicated by the PIRS-20 was found to be significantly reduced"},{"id":"research","evidence":"data from only 12 participants were evaluated"}],"summary":"Quotes a small blinded crossover pilot study using baby-monitor RF exposure in adults, describing reduced reported sleep quality and EEG differences alongside unchanged heart-rate variability and actigraphy.","reviewed_at":"2026-10-28T23:54:32Z","review_method":"Full comment-text review with exact source evidence; attachments not reviewed","review_source_sha256":"6e49449dfa14b0255f21dff1babf1879ff9963af2684b0ccb6f8767eecc3080d","source_url":"https://rfsafe.net/hhs-comments/data/catalog.json","scope":"Original comment body; attachments excluded"},"forum_topics":["neurological","research"],"primary_topic":"neurological","forum_title":"Quotes a small blinded crossover pilot study using baby-monitor RF exposure in adults, describing reduced…"}
