# Low-frequency household noise linked to kidney damage in mice 2026-08-09T02:17:38+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet Scientists at Nagoya University have found that low-frequency noise from common household appliances can damage kidneys in mice. The study, reported by Medical Xpress, exposed mice to recordings from an outdoor air-conditioning unit and a heat-pump water heater for 12 hours each night over five days. Mice exposed to the full noise showed higher levels of creatinine and blood urea nitrogen, markers of kidney injury. The effect was reproduced by the low-frequency component alone, even though the sound was below the mice’s hearing range. The researchers also found swelling in the glomeruli, the kidney’s filtering units, and increased production of endothelin-1, a molecule that constricts blood vessels. Mice given a drug that blocks endothelin showed less damage, suggesting a possible mechanism. The findings do not prove that household noise damages human kidneys, but they highlight the need to study low-frequency noise as a distinct environmental health threat. ## Coverage - economictimes.indiatimes.com Tags: environmental health, kidney damage, low-frequency noise, mice study, Nagoya University, noise pollution Canonical: https://indianopinion.org/low-frequency-household-noise-linked-to-kidney-damage-in-mice/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
