but not significant (OR 1.019 [95% CI: 0.991-1.047]). The PM effect was significantly stronger on high-temperature days (above the 75th percentile) than on low-temperature days (PM2.5, high: OR 1.068, low: OR 1.021, Pinteract = 0.03; PM10, high: OR 1.066, low: OR 1.014, Pinteract = 0.02).
“Conclusion: Our study provides new evidence that air pollution exposure may trigger migraine especially on high-temperature days, and this finding may contribute in establishing preventive measures against migraine.” (Source: PubMed)

Industrial environments may disturb sleep through:
nighttime operations,
lighting,
rail traffic.
backup systems,
shift-related activity.
Sleep disturbance is among the most consistently recognized factors associated with migraine attacks and may also influence long-term disease susceptibility through changes in hypothalamic-and-autonomic-regulation.-(Source: ChatGPT-to-Pubmed)
Results: "Although some factors are controversial, migraineurs worldwide consistently report similar environmental triggers. However, few studies confirm environmental influences on migraine and headaches. Research to date indicates that migraineurs have lower thresholds for light-induced discomfort, sine grating distortion and illusions, noise tolerance and olfactory sensitivity compared to the general population."
Conclusion: "There are conflicting studies supporting the validity of patient-reported environmental migraine triggers. Prospective studies are needed to determine the extent that external stimuli influence the migraine process. Decreased thresholds for light, noise, olfactory and visual stimuli in migraineurs may be minimized by modifying the work, home and classroom settings." (Source: Pubmed)
