April 7: World Health Day

April 7 is World Health Day, a day promoted by the World Health Organization to raise awareness among citizens, institutions, and the scientific community about issues that affect public health. Every year, this day is an important opportunity to reflect on how to improve living conditions and prevent risks related to the environment, lifestyles, and the contexts in which we live.

When it comes to health, the focus is often on nutrition, physical activity, and preventive healthcare. However, one of the most decisive factors for daily well-being is the quality of the air we breathe, especially indoors. Indoor air quality is increasingly recognized as a key factor in health, productivity, and quality of life.

Indoor air: an often underestimated factor

In everyday life, we spend most of our time indoors. Homes, offices, schools, transportation, gyms, and public places are environments where we spend about 90% of our days. For this reason, indoor air quality has a direct impact on our bodies.

Unlike outdoor air pollution, indoor pollution is often less noticeable and less monitored, but it can be just as significant. Various pollutants can accumulate inside buildings, including fine particulate matter (PM10 and PM2.5), volatile organic compounds (VOCs), carbon dioxide (CO₂), formaldehyde, allergens, mold, and biological agents. These substances can come from many different sources: building materials, furnishings, cleaning products, heating systems, domestic activities such as cooking or cleaning, or even from the presence of people in closed environments.

Breathing poor-quality air indoors can have significant consequences on people’s well-being. The effects can be both short-term and long-term. The most common symptoms associated with poor indoor air quality include: irritation of the eyes, nose, and throat; headaches and fatigue; difficulty concentrating; a feeling of heavy or poorly ventilated air; and aggravation of allergies and respiratory problems. In the long term, prolonged exposure to certain pollutants can contribute to the development or worsening of respiratory and cardiovascular diseases.

Smarter buildings and healthier environments

Indoor air quality is becoming an increasingly important factor in the design of modern buildings. Sustainable architecture and smart building technologies aim to create environments that are not only energy efficient, but also healthy for the people who live in them.

Air quality measurement systems now allow us to constantly monitor the conditions of what we breathe so that we can take preventive action in case of critical issues. These solutions help improve indoor comfort, reduce health risks, and promote safer and more productive spaces.
