Dust is a common air pollutant that can be widely categorized into several others. A pollutant is a substance introduced to the atmosphere and has a negative or unwanted effect. Dust may come from rock, sand, natural erosion of soil and pollens are also parts of dust in the atmosphere. Dust particles are of different sizes including visible and invisible dust particles. Smaller dust particles stay longer in the air and travel further. Large particles of dust fall out of the air almost close to where they are formed. Large particles tend to be captured easily in the mouth and nose when you breathe. Fine particles of dust are more likely to spread deeply into the lungs while superfine particles can be absorbed directly into the bloodstream. Toxicity of dust is determined by the size and type of a dust and particle. The level of harm caused by dust is mostly determined by the time period of exposure to dust and the amount of dust in the air.
Most common health effects on health caused by dust are:
Even small concentrations of dust can worsen the symptoms of respiratory conditions like chronic obstructive airways disease and asthma. Breathing in a high concentration of dust for many years can reduce lung function and contribute to lung disorders, chronic bronchitis, and heart disorders. Longer you breathe in the dust, greater the chances that it will impact your health. Breathing lower levels of dust does not cause health issues in most individuals. People having heart and respiratory conditions are at higher risk of acquiring long-term health issues. Infants, children, and elderly people are more likely to have health problems from long-term exposure to a high amount of dust.
When people susceptible to lung disease, breathe a high concentration of dust, they experience more problems. But dust can affect anyone in the following ways.
Breathing problems: Persistent exposure to dust can cause breathing issues including mild discomfort to severe issues like asthma attacks. Dust may even trigger asthma symptoms.
Sneezing and coughing: Breathing dusty air is not good for the lungs. Coughing and sneezing are typically the starting symptoms when you get exposed to dust.
Allergies: Dust allergies are common and can trigger issues like abdominal pain, dizziness, and skin rashes. Dust allergies can be managed by avoiding exposure to dust. Allergy shots given seasonally also help.
Eye irritation: Dust can cause eye irritation including watery, itchy, puffy or red eyes.
