Aircraft noise has short-term associations with cardiovascular events, particularly during the previous evening and early morning hours. Factors such as age-sex, ethnicity, deprivation, and season can modify these effects. High noise variability at night may be associated with higher risks. The mechanisms behind these associations include sleep disturbance, increased blood pressure and stress hormone levels, and impaired endothelial function.
Aircraft noise causes annoyance and sleep disturbance and there is some evidence of associations between long-term exposures and cardiovascular disease (CVD). We investigated short-term associations between previous day aircraft noise and cardiovascular events in a population of 6.3 million residing near Heathrow Airport using a case-crossover design and exposure data for different times of day and night. We included all recorded hospi-talisations (n = 442,442) and deaths (n = 49,443) in 2014-2018 due to CVD. Conditional logistic regression was used to estimate the ORs and adjusted for NO2 concentration, temperature, and holidays. We estimated an in-crease in risk for 10 dB increment in noise during the previous evening (Leve OR = 1.007, 95% CI 0.999-1.015), particularly from 22:00-23:00 h (OR = 1.007, 95% CI 1.000-1.013), and the early morning hours 04:30-06:00 h (OR = 1.012, 95% CI 1.002-1.021) for all CVD admissions, but no significant associations with day-time noise. There was effect modification by age-sex, ethnicity, deprivation, and season, and some suggestion that high noise variability at night was associated with higher risks. Our findings are consistent with proposed mechanisms for short-term impacts of aircraft noise at night on CVD from experimental studies, including sleep disturbance, increases in blood pressure and stress hormone levels and impaired endothelial function.
