Asthma is one of the most common chronic respiratory conditions. Millions of people are affected by it, and sooner or later, many wonder what actually causes asthma. However, there is no simple answer to this question. In most cases, asthma results from a combination of various factors. In addition to a genetic predisposition, environmental conditions and certain airborne irritants also play an important role.
In particular, the quality of the air we breathe every day can have a significant impact on our respiratory system. Pollutants, allergens, or even poor indoor air quality can exacerbate symptoms and even trigger an asthma attack. This is another reason why monitoring air quality is becoming increasingly important.
What happens in bronchial asthma?
Bronchial asthma is a chronic inflammation of the airways. The bronchial tubes become hypersensitive to certain triggers. When these triggers are inhaled, the airways narrow. At the same time, the mucous membranes swell and produce more mucus. This makes breathing significantly more difficult.
Typical symptoms include shortness of breath, coughing, or a wheezing sound when exhaling. These symptoms often occur in episodes. However, between episodes, those affected may experience few or no symptoms for extended periods of time.
Bronchial asthma is often caused by chronic inflammation of the airways, which makes them particularly sensitive. Even relatively minor irritants can then trigger severe reactions.
What can cause asthma?
The development of asthma can rarely be attributed to a single trigger. Rather, it is the result of a combination of factors. Genetic predisposition plays an important role. People with a family history of allergies or asthma have a significantly higher risk of developing the condition themselves.
In addition to this genetic predisposition, environmental factors can also contribute to the development of the disease. These include, for example, air pollution, tobacco smoke, or certain chemical irritants. Such substances can irritate the airways over the long term and promote inflammatory processes.
Allergies are also a common cause of bronchial asthma. In this case, it is referred to as allergic asthma. In this condition, the immune system reacts hypersensitively to otherwise harmless substances in the environment, such as pollen, dust mites, or mold spores. If these substances enter the airways, they can trigger an inflammatory reaction.
Common triggers of an asthma attack
While the causes of the condition often have long-term effects, there are certain factors that can trigger acute symptoms. Such irritants are considered typical triggers of asthma or triggers of an asthma attack.
Allergens are a particularly common trigger. During the spring pollen season, many people with asthma experience a worsening of their symptoms because pollen easily enters the airways through the air. Dust mites and pet dander can also exacerbate asthma symptoms.
In addition, air pollutants can play a significant role. particulates, smoke, or volatile chemical compounds irritate the respiratory tract and can exacerbate existing inflammation. Indoors in particular, such substances often go unnoticed—for example, from cleaning products, new furniture, or certain building materials.
In addition to these factors, respiratory infections, physical exertion, or very cold air can also trigger an asthma attack. How sensitive a person is to such triggers varies greatly from person to person.
Why indoor air quality is especially important for asthma patients
One crucial factor is often overlooked in everyday life: people spend a large part of their time indoors. This makes the quality of indoor air all the more important.
Indoors, various substances can accumulate that can irritate the respiratory tract. These include fine dust particles, volatile organic compounds from furniture or paint, and high humidity, which promotes mold growth. Many of these factors are invisible and are therefore often not noticed until symptoms have already appeared.
However, especially for people with sensitive airways, poor indoor air quality can be a major trigger for asthma. That is why it can be a good idea to check the air quality regularly.
How the air-Q Can Help with Asthma
An air quality monitor like the air-Q can help identify potential pollutants in indoor air. The device measures various air quality parameters and displays changes in real time.
These include, among other things, fine particulate matter, volatile organic compounds, carbon dioxide, temperature, and humidity. These measurements indicate whether there are potential irritants in the indoor air that could irritate the respiratory tract.
This transparency can be helpful for people with asthma. For example, if certain pollutant levels rise after cooking, cleaning, or ventilating, it becomes easier to understand the connection between air quality and symptoms.
Such measurements can also be helpful when it comes to proper ventilation. Rising CO₂ levels or increased concentrations of pollutants indicate when it is advisable to ventilate the room. This allows for targeted improvement of indoor air quality.
In the long term, continuous monitoring of air quality can also help identify recurring sources of pollution. This makes it easier to avoid potential triggers of asthma attacks in everyday life.
Asthma is usually caused by a combination of genetic predisposition and various environmental factors. Substances in the air, in particular, play a significant role, as they can irritate the sensitive airways or trigger allergic reactions.
The main triggers of asthma include pollen, dust mites, air pollutants, and mold spores. Many of these factors are also present indoors, which is why indoor air quality can have a significant impact on the well-being of asthma patients.
By making various pollutants and environmental factors visible, air quality monitors like the air-Q can help identify potential sources of pollution early on. This enables those affected to make more informed choices about their environment and better avoid potential triggers of asthma attacks in their daily lives.
