Various pollutants have been linked to neurological effects that can influence mood and stress resilience
It has been suggested that traffic and other environmental noise and light pollution increase stress levels through disruption of the body clock.

The authors of the study pointed out that environmental exposures and their link to depression and anxiety has been extensively studied, but their potential effect on the risk of suicide was less well understood. The researchers wanted to find out whether air, noise, light and water pollution, and sociodemographic factors such as sex and income, might influence the risk of death by suicide and suicidal behaviours. Thirty-three studies investigated death by suicide, seven examined suicidal thoughts, and five, attempted suicide.
Most studies looked at the effects of air pollution exposure , three looked at water pollution, three at noise pollution, and one at light pollution. The researchers pointed out that air pollutants as well as water polluted with arsenic, lead, lithium or nitrate, have been linked to neurological effects, including chronic inflammation and nerve damage, which can impair brain function and influence mood and stress resilience.
It has been suggested that traffic and other environmental noise and light pollution increase stress levels through disruption of the body clock, they explained. However, they concluded: “These findings bring to attention the critical importance of recognising environmental exposures as modifiable risk factors within suicide prevention efforts.
“Integrating environmental health into mental health policy, through cross-sectoral collaboration, pollution reduction strategies, and targeted public health interventions, could play a vital role in reducing suicide risk and improving overall population mental wellbeing. ”Social media algorithms carefully designed to reward reckless youthful behaviourIrishman in Lapland: ‘I bought a house for €32,000.
