City air or country air? How air quality influences asthma and allergies

Asthma Allergy City and Country Air Comparison

Asthma and allergies are among the most common chronic conditions. Many sufferers ask themselves whether the air in the countryside is really healthier than in the city. Studies show that people in large cities suffer from asthma and allergies more often than residents of rural regions. At the same time, rural areas have fewer classic pollutants but bring their own risks such as pollen, dust and smoke. This article explains how asthma allergies behave in different environments, which factors influence “asthma air” and how you can use an app to control your symptoms more effectively.

Urban burdens – why city air can worsen asthma

City air is characterized by traffic exhaust fumes, ozone and fine dust. In many metropolises, air pollution from cars hardly decreases; it contains gases such as nitrogen dioxide as well as fine particles that penetrate deep into the lungs. Studies show that people living in cities suffer from asthma and allergies more often. Short‑term peaks can worsen existing asthma, and long‑term exposure increases the risk of developing asthma in the first place.

A French study found that even small increases in benzene, sulfur dioxide and PM₁₀ significantly increased the risk of asthma in children. In addition, air pollutants enhance the allergenic effect of pollen: polluted pollen can irritate the airways more strongly and trigger allergic reactions. Besides these pollutants, factors such as passive smoking, mold in old buildings, stress and insufficient ventilation also act as additional burdens in cities.

Rural risks – clean air with a downside?

According to the CDC, the overall air quality is better in the countryside: in less densely populated regions, ozone and fine dust limit values are exceeded much less often. In a US analysis, large metropolises experienced ten times more days of poor air quality than rural areas. Ozone levels also decrease measurably from city to country. There is also a difference between Sea vs Mountains.
But the asthma air in the countryside harbors other dangers. Pollen from grasses, trees and weeds are more frequent in rural areas and can trigger hay fever and asthmatic complaints. Other natural pollutants include smoke from wildfires and dust storms, which occur mainly in dry regions. These events release large amounts of fine dust and pose a risk, especially for people with asthma. In addition, agriculture and animal husbandry can release ammonia, pesticides or animal hair into the air, which can be burdensome for sensitive individuals.

Comparison and tips – how to use your environment

Whether city or country air is better cannot be answered across the board. Cities have higher pollutant loads, which increases the likelihood of asthma and allergies. A systematic analysis of 63 studies even showed that the risk of asthma is significantly higher in urban regions (odds ratio 1.46–1.96). In the countryside, however, there are fewer industrial and traffic emissions but more pollen, smoke and dust. Therefore, it is important to know the specific triggers in your environment.

Conclusion – a conscious approach to asthma and allergies

Whether you live in the city or in the country: air quality plays a major role for asthma allergies. Cities burden you through pollutants and traffic, while rural regions present their own challenges with pollen, smoke and dust. With a conscious lifestyle, up‑to‑date information on asthma air and the support of digital helpers such as the Breathment app, you can better understand your symptoms and actively counteract them.
