Community Noise, Urbanization, and Global Health: Problems and Solutions

Do neighbourhood traffic-related air pollution and socio-economic status moderate the associations of the neighbourhood physical environment with cognitive function? Findings from the AusDiab study

“…As expected, and evidenced by this study, more walkable neighbourhoods typically encourage active modes of transport (e.g., walking for transport) (Cerin et al, 2017) and engagement in leisure-time physical activity (Van Cauwenberg et al, 2018), which are beneficial to cardiometabolic health (Bai et al, 2022;Ballard et al, 2021;Lee et al, 2021). However, they are also accompanied by higher levels of air pollution (James et al, 2015) and noise (Salter et al, 2015) that can be detrimental to health (Basner et al, 2014;Gaio et al, 2019;Liu et al, 2019;Salter et al, 2015;Wang et al, 2023). Although this study partially accounted for ambient air pollution, it did not account for urban noise, and this may explain the positive associations of neighbourhood walkability with MAP observed even after adjustment for antihypertensive medication.…”

“…Sleep disruption, oxidative stress and changes in sympathetic tone triggered by affective reactions associated with exposure to noise are thought to be the main mechanisms responsible for these findings (Basner & McGuire, 2018;. Problems arising from urban noise could be mitigated through appropriate urban and traffic planning policies (e.g., pedestrian zones, land use planning) and technological interventions (e.g., installation of double-glazed windows and road resurfacing) (Salter et al, 2015). Clearly, to understand the potential impact of dense, destination-rich neighbourhoods on various cardiometabolic risk factors for CVD, it is important to consider aspects of urban design as well as noise and air pollution exposures.…”

Neuroprotective role of Glycyrrhiza glabra on chronic noise induced changes in Hippocampal morphology and its functions in wistar albino rats

“…The health impacts caused by excessive environmental noise are a growing concern. Noise exposure has been linked to a variety of health effects, including hearing loss, cardiovascular damage, cognitive impairment, and sleep disturbance and annoyance (2). Enormous studies have shown that noise above 90dB increases the stress hormones and can cause significant impact on human h e a l t h .…”
