Question explored with the scientific record
Does power quality distortion known as dirty electricity near data centers have documented health effects in humans?
The short version: the evidence that dirty electricity from data centers causes documented health effects in humans is thin, indirect, and comes from a handful of small studies in different settings, not from data centers themselves.
The single most relevant study is a 2008 paper on a California middle school where teachers had a cancer rate nearly three times the expected number [11]. The researchers measured "high frequency voltage transients" using a Graham/Stetzer meter and found a dose-response pattern: teachers with higher cumulative exposure had higher cancer risk. For all cancers combined, 18 cases were observed where 6.5 were expected, a risk ratio of 2.78 [11]. Malignant melanoma and thyroid cancer showed even larger ratios, 9.8 and 13.3 respectively, though the absolute numbers were small (4 and 2 cases) [11]. This is a single observational study in one school, not a data center, and it cannot prove causation.
A 2013 study looked at neurotransmitter changes when dirty electricity was reduced in a library and near a cell tower [12]. Urinary dopamine and phenylethylamine levels fluctuated over 18 weeks of filtering, but the pattern was erratic and the sample was tiny (7 people at the start, 6 by the end) [12]. The authors argued dirty electricity acts as a chronic stressor, but the data does not support a clear conclusion.
The rest of the retrieved evidence is about power quality engineering: how to detect harmonics in motors, transformers, and railway systems [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 14, 15, 16, 17, 18, 19]. These papers confirm that data centers and other large electrical loads produce harmonic distortion, voltage transients, and frequency noise. But they measure effects on equipment, not on people. A 2016 study showed that voltage harmonics cause 100 Hz torque oscillations and 300 Hz vibrations in induction motors [5]. That is a mechanical effect on a machine, not a biological effect on a human.
What is missing from this retrieval is any study that measures health outcomes in people living or working near a data center specifically. No blood work, no symptom surveys, no long-term follow-up. The closest we have is the school study [11], which was in a different setting and used a measurement method (Graham/Stetzer meter) that is not standard in power quality engineering. The mechanism by which high-frequency voltage transients might cause cancer or neurotransmitter changes is not established in these records.
My call: the evidence does not support a claim that dirty electricity from data centers causes documented health effects in humans. The school study is suggestive but cannot be generalized, and no study has tested the question in the data center setting. Confidence: low.
