  "summary": "This double-blind randomized placebo-controlled crossover pilot study tested 2.45 GHz RF-EMF exposure from a baby monitor during sleep in 12 healthy adults. Subjective sleep quality (PIRS-20) was significantly worse during RF-EMF exposure versus sham, and EEG power density increased in higher-frequency bands during NREM sleep. HRV and actigraphy outcomes did not differ significantly. The authors state that larger real-world studies with specified dosimetry are needed to confirm the findings.",
  "key_points": [
    "The study used a double-blind randomized crossover design comparing active versus sham baby monitor exposure during sleep.",
    "Exposure frequency was 2.45 GHz (Wi-Fi band) over 7 nights per condition with a one-week washout.",
    "Subjective sleep quality (PIRS-20) was significantly reduced during RF-EMF exposure compared with sham.",
    "EEG power density increased in gamma, beta, and theta bands during NREM sleep under exposure.",
    "No statistically significant differences were found in HRV outcomes between exposure and sham.",
    "No statistically significant differences were detected in actigraphy measures between exposure and sham.",
    "The authors emphasize the need for larger studies with specified dosimetry to confirm results."
