Indoor air quality and why it matters
Many of the allergens that cause an allergic reaction can be found in our own homes (and even our place of work). House dust mites, for example, are tiny creatures, just a quarter of a millimetre long. House dust mite allergy is very common and associated with asthma, eczema, and perennial allergic rhinitis. Mites are found in carpets, soft furnishings, and clothing but a significant amount of exposure to house dust mite allergens happens in bed. You can take measures to avoid house dust mite, which will help, but will not entirely remove dust mite allergens.
Mould is another culprit. It is the spores from mould that can trigger allergic symptoms such as runny/itchy nose, itchy eyes, eczema and, most importantly, asthma. There are ways to avoid moulds – ventilation is key to help stop moulds flourishing in a damp environment. Maintaining optimal humidity levels is crucial in preventing mould growth and dust mites. High humidity can create an environment conducive to these allergens, while low humidity can dry out respiratory passages, potentially triggering asthma symptoms.
Poor air quality can contribute to the exacerbation of asthma symptoms, making it essential to create an environment that supports your respiratory well-being.
Outdoor air quality and why it matters
Air pollution is the top environmental risk to human health in the UK, and the fourth greatest threat to public health after cancer, heart disease and obesity.
It makes people more susceptible to respiratory infections and other illnesses and it can have a significant impact on those living with allergies. There is a proven link between the quality of the air we breathe and the health of people living with allergic disease. Sensitivity to the adverse effects of air pollutants will vary in individuals and air pollution levels will also vary seasonally, from day to day, as well as by the time of day.
Poor outdoor air quality often contains higher levels of pollutants such as particulate matter, ozone, and nitrogen dioxide. Exposure to these pollutants can exacerbate asthma symptoms, leading to increased coughing, wheezing, shortness of breath, and chest tightness among individuals with asthma. Prolonged exposure to outdoor air pollution has been linked to decreased lung function. For individuals with asthma, compromised lung function can worsen their ability to breathe comfortably and contribute to a decline in overall respiratory health.
In sumary, poor outdoor air quality poses a significant threat to individuals living with asthma, exacerbating symptoms, triggering attacks, and potentially impacting their overall respiratory health. It underscores the importance of environmental awareness, proactive measures to reduce exposure, and effective asthma management strategies to mitigate the adverse effects of polluted air.
