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.

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 .

Myopia, or nearsightedness, is on the rise worldwide, particularly among children living in urban areas across East Asia. While genetics, screen time, and lack of outdoor activity have long been cited as key risk factors, a new and often overlooked element is now drawing attention: air pollution. A large-scale study from China, published in the Proceedings of the National Academy of Sciences (PNAS), offers new evidence that pollutants in the air may have a direct impact on ch

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.

Just a few years ago, Rajshahi was known as a “green city.” Local authorities had implemented progressive transport planning, protected green spaces, and promoted environmental awareness. The city boasted some of the best air quality in the country.

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?

Air quality directly impacts health, causing severe conditions and premature deaths globally - awareness drives advocacy and solutions.
