We tend to think of our indoor air as safer than the polluted air outside. But studies show that indoor air can be up to five times more polluted. One of the most underestimated sources? VOCs. What Are VOCs? VOCs stands for “Volatile Organic Compounds” – chemical substances that evaporate at room temperature and enter the indoor air. Common examples include: Formaldehyde, Benzene, Toluene, Acetone, Terpenes. These compounds are emitted by a surprising number of everyday items

Essential oil diffusers promise relaxation and fragrance, yet their vapours carry hidden dangers. This report explains how different diffuser types work, the psychology of aromatherapy and scientifically noted benefits like stress reduction and better sleep. However, it also details emissions of VOCs, nanoparticles and allergens, highlighting potential health risks for adults, children and pets.

Scented candles create a cosy atmosphere but release harmful pollutants. Researchers found they emit ultrafine particles, carbon monoxide, nitrogen oxides, volatile organic compounds, heavy metals and polycyclic aromatic hydrocarbons. These emissions raise the risk of respiratory, heart and cancer illnesses. Natural waxes like beeswax, rapeseed or soy are safer alternatives.

In mid‑October 2025, storm Alice hammered Spain with torrential rain, causing floods in Catalonia, Valencia and the Balearic Islands . The deluge forced rail lines to close and dozens of flights were cancelled . After the water recedes, quick action is essential: mould can start growing within 24–36 hours, so experts advise removing standing water promptly, airing out rooms and using dehumidifiers.

Air exchange is key: without sufficient ventilation, carbon dioxide (CO₂) levels rise, a sign of poor air quality. A U.S. study in elementary schools found CO₂ concentrations above 1,000 ppm in most classrooms, indicating inadequate ventilation . These rooms had more respiratory viruses detected in air and nasal samples, while classrooms with higher air exchange showed about an 80 percent lower infection risk .

Dementia is one of the fastest-growing global health challenges. While age remains the primary risk factor, emerging research reveals another, often overlooked contributor: air pollution. In her article for the European Public Health Alliance (EPHA), “Addressing air pollution to reduce dementia risk”, Angela Bradshaw highlights the growing body of evidence linking long-term exposure to polluted air with cognitive decline and dementia.

When you hear the word “fine dust,” your first thought might be of traffic, factories, or polluted city air. But what many people don’t realize is that indoor air can often be more polluted than the air outside – and fine dust is a major culprit. Even in clean, modern homes, tiny airborne particles accumulate from everyday activities. These particles can harm your health, reduce your concentration, and lower your overall well-being.

Fine dust refers to tiny particles suspended in the air that, due to their small size, can easily be inhaled. These tiny particles are often invisible but significantly impact our health and environment. But what exactly is fine dust, and why is it so dangerous?
