Airport and Airplane Noise Linked to Poor Heart Health
Recent studies have shown a strong association between exposure to airport and airplane noise with the deterioration of heart health. With the steady rise in air travel worldwide, the impact of noise pollution created by airports and airplanes has been an area growing in concern.
The Impact of Noise Pollution on Heart Health
Exposures to high levels of noise, especially those coming from airports and airplanes, have been associated with several negative health effects, including cardiovascular diseases. Studies have shown that noise pollution can increase blood pressure, heart rate, and stress levels—all of which are risk factors for heart-related diseases.
How Noise Impacts Heart Health
The mechanism through which noise affects heart health is quite complex. Loud noises from airplanes and airports cause temporary disturbances in the body’s autonomic nervous system, which results in the release of stress hormones like adrenaline and cortisol. This can eventually lead to serious cardiovascular problems if one is chronically exposed to these heightened levels of stress.
Furthermore, exposure to high noise has been found in research to interfere with sleep, a potent risk factor for coronary heart disease. Not getting enough high-quality rest or continuously being aroused during rest promotes inflammation, also a determinant of heart health.
Research Findings on Airport and Airplane Noise
A study published by researchers from the University of Zurich analyzed data from more than 50,000 people living near airports and found a strong correlation between airport noise and poor heart health. People who lived near busy airports reported higher rates of high blood pressure, heart disease, and strokes than those in quieter areas.
Similarly, the European Heart Journal noted that noise-induced stress has been associated with cardiovascular morbidity, particularly in those exposed to chronic noise pollution from aircraft and airport activities.
The Role of Government and Industry Response
These findings have been responded to by both governments and aviation industries in efforts to reduce the impact of noise pollution. Noise reduction strategies being considered include the use of quieter aircraft, upgrading soundproofing at airports, and improving urban planning around air traffic hubs.
Moreover, public health policies are encouraging the inclusion of noise reduction features in all urban development projects to protect the welfare of inhabitants.
MENTAL HEALTH AND NOISE EXPOSURE
In addition to the impacts on physical health, noise pollution has also been linked to mental health issues, including anxiety and depression. Chronic stress from high levels of noise exacerbates mental health disorders, which further impacts the well-being of the heart.
Strategies to Reduce Noise Pollution
While complete eradication of noise pollution may be unrealistic, steps can be taken to reduce its effects. These include:
- Noise barriers: Installation of physical barriers around airports and residential areas.
- Improved urban planning: Zoning laws, to keep industrial and residential areas separate.
- Use of quieter aircraft: Encouraging the development and use of quieter airplane models.
- Community Awareness: Raising public awareness about the risks of noise pollution and the benefits of home soundproofing.
