Question explored with the scientific record
Do data centers or server farms cause health problems in nearby residents?
The honest answer: the retrieved evidence does not show data centers causing illness in nearby residents. It shows they burn a lot of power and water, and that the health case rests on pollution and noise, not on the servers themselves.
The records that actually touch your question are about the environmental footprint, not resident health. A 2026 review notes data centers rely on diesel backup generators that emit nitrogen oxides and fine particles locally [1], and that global data center electricity demand is projected to exceed 1,000 TWh by 2026 [1]. That is the plausible harm pathway: local air pollution from backup power, plus noise. The rest of the retrieved set is about air pollution and noise in general, not about data centers specifically. Road traffic noise at home was associated with more hyperactivity and emotional symptoms in children [2], and perceived pollution tracked with poorer sleep in a large Korean sample [3]. Those are general exposures, not data center exposures, and they are observational.
| What the records show | Finding | Scope |
|---|---|---|
| Diesel backup emissions | NOx and fine particles released locally [1] | Data centers |
| Global power demand | Over 1,000 TWh projected by 2026 [1] | Data centers |
| Road noise and children | More hyperactivity, emotional symptoms [2] | Traffic, not data centers |
| Perceived pollution and sleep | Poorer sleep with more pollution types [3] | General population |
What this retrieval cannot see: any study measuring health outcomes in people living near a specific data center. None surfaced. That is a gap in the search, not proof no such work exists. The mechanism worth watching is local diesel exhaust and noise, and those are measurable.
My call: no direct evidence of harm to nearby residents in these records, but the local diesel and noise pathway is real and understudied. Confidence: low.

Association between perceived environmental pollution and poor sleep quality: results from nationwide general population sample of 162,797 people
Perceived environmental pollution is linked to poorer sleep quality in a nationwide Korean adult sample, with higher odds when multiple pollutants are perceived, especially in rural areas.
