In Bankers Hill, San Diego, a peaceful spring afternoon is interrupted every three minutes by the roar of jets, highlighting the health risks of chronic noise. Research shows that such noise, which can occur over 280 times daily, is linked to increased risks of hypertension, stroke, and heart attacks. This issue affects more than 100 million Americans, with noise exposure from daily life having long-lasting health impacts. People living in noisy environments may think they have adapted, but data suggests prior noise exposure amplifies the negative effects. Even in rural areas, sudden loud noises can be particularly harmful.

Investigations reveal that noise exposure can activate the amygdala, increase blood pressure, and stiffen arteries. Studies have shown that people living in high-noise areas have more active amygdalas and arterial inflammation, leading to major cardiac events. Noise exposure is a significant risk factor, with increases in noise levels directly correlating to higher risks of cardiovascular diseases.

Noise exposure disparities exist, affecting poorer communities and people of color more severely. Schools in noisy areas see lower academic performance and higher stress levels among children. Nighttime noise is particularly detrimental, disrupting sleep and causing long-term health issues.

Regulatory efforts in the U.S. have lagged behind those in Europe, where stricter noise control measures are in place. European cities have implemented various strategies to reduce noise and its health impacts. Reducing noise by even a small amount could yield significant economic benefits by decreasing healthcare costs and improving productivity. Addressing noise pollution requires comprehensive policy changes at all levels of government.
