Invisible Killers
How Airborne Viruses & pollutants destroying Health Worldwide
Airborne viruses and pollutants pose significant threats to human health, with their effects becoming more concerning due to increasing levels of air pollution and global viral outbreaks. They pose significant risks to public health, particularly in today’s rapidly changing environment.
Respiratory Diseases
Airborne viruses such as influenza and Corona virus can lead to acute respiratory infections, while pollutants like particulate matter (PM) and nitrogen dioxide (No2) exacerbate chronic respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD)
Cardiovascular Diseases
Cardiovascular diseases caused or exacerbated by airborne viruses and pollutants can be linked to respiratory issues, systemic inflammation and oxidative stress which can negatively affect the heart and blood vessels.
(A) Myocarditis
Description: inflammation of the heart muscle (myocardium) often caused by viral infections.
Causes: *Coxsackievirus B *Influenza virus
*SARS Cov-2 ( (virus that causes COVID-19)
*Adenoviruses trigger inflammation in the heart impairing its ability to pump blood efficiently.
(B) Pericarditis
Description: inflammation of the pericardium the sac like membrane around the heart.
Causes:
*Influenza Virus *SARS CoV-2 *Coxsackievirus *Enteroviruses
Mechanism: Viral infections can lead to inflammation of the hearts surrounding tissues, causing chest pain and heart function issues.
(C ) Ischemic Heart Disease (IHD) linked to pollutants
Description: Also known as coronary artery disease, it is caused by narrowing or blockage of the coronary arteries reducing blood flow to the heart.
Causes: Particulate matter (PM2.5 and PM10) fine particles from vehicle emissions, industrial pollutants and burning of fossil fuels.
Nitrogen Dioxide (No2) and Sulfur Dioxide (SO2) emitted from cars, power plants and industrial facilities.
Mechanism: Air pollutants cause systemic inflammation, oxidative stress, and vascular dysfunction which can accelerate atherosclerosis (plaque buildup in the arteries)
(D) Hypertension
Description: High blood pressure that increases the risk of heart attack, stroke, and heart failure.
Causes: particulate matter PM2.5 and Ozone (O3)
Mechanism: Air pollution may cause an inflammatory response and constriction of blood vessels, leading to elevated blood pressure over time.
(E) Arrhythmias
Description: irregular heartbeats that can lead to more severe conditions like atrial fibrillation or sudden cardiac arrest.
Causes: Particulate matter PM2.5 linked to abnormal heart rhythms, especially in people with pre existing heart conditions.
Mechanism: Pollutants can trigger oxidative stress and inflammation affecting the electrical pathways of the heart.
(F) Heart Failure
Description: A chronic condition in which the heart is unable to pump blood efficiently leading to fluid buildup and fatigue.
Causes: SARS-CoV-2 can cause severe heart damage in some patients leading to heart failure.
Particulate matter PM2.5 long term exposure can weaken the heart’s ability to pump blood.
Mechanism: Both viruses and pollutants can induce systemic inflammation and oxidative stress leading to damage of the heart muscle over time.
(G) Atherosclerosis
Description: Hardening and Narrowing of the arteries due to plaque buildup, increasing the risk of heart attacks and strokes.
Causes: particulate matter pm 2.5 and carbon monoxide chronic exposure can accelerate plaque formation.
Mechanism: Air pollution triggers inflammation and oxidative stress, promoting the development of plaques in blood vessels.
(H) Thrombosis
Description: Formation of blood clots inside blood vessels, which can lead to heart attacks or strokes.
Causes: particulate Matter pm 2.5 and No2 exposure to these pollutants has been linked to an increased risk of blood clot formation.
Mechanism: Pollutants may cause changes in blood viscosity and promote inflammation, leading to a higher risk of clot formation.
(I ) Pulmonary Hypertension
Description: Increased Blood pressure in the arteries of the lungs, which puts stain on the right side of the heart.
Causes: Ozone (O3) and PM2.5 linked to the development of pulmonary hypertension.
SARS-CoV-2 causes severe lung and vascular damage, contributing to pulmonary hypertension.
Cognitive Impairment
Airborne Viruses and pollutants can significantly impact cognitive function, potentially leading to impairment in several ways.
(A) Airborne viruses
Sars CoV-2 COVID 19 can lead to neurological symptoms and cognitive impairment referred to as “Brain fog” the virus affect the nervous system directly through the olfactory pathways or by crossing the blood brain barrier
(B) Influenza Viruses
Severe flu can trigger cognitive issues, especially in older adults. The intense immune response, including cytokine release, may affect brain function, causing confusion and temporary declines in cognitive capacity.
(c ) Herpes Simplex Virus
Persistent or reactivating herpes viruses like HSV1 have been linked to cognitive impairment and an increased risk of Alzheimer’s disease in susceptible individuals.
(D ) Particulate Matter PM2.5 & PM10
Fine particulate matter can penetrate deep into respiratory system and even enter the blood stream, eventually reaching the brain. These particles have been associated with inflammation oxidative stress and even direct toxicity to neurons which can impair cognitive function and increase the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s.
(E) Heavy Metals like lead Mercury
causes cognitive deficits and damage the nervous system and chronic exposure to Nitrogen and sulfur dioxide trigger inflammation and contribute to cerebrovascular diseases that affect cognitive abilities.
(F) Volatile Organic Compounds VOCs
such as benzene, formaldehyde and toluene can be inhaled from air pollution or household chemicals affecting brain health over time excessive exposure will lead to memory problems headaches and impaired cognitive function
So this is how airborne viruses and pollutants are silently but severely impacting health worldwide, contributing to the spread of respiratory illnesses, weakened immune systems, and overall poor quality of life. The adoption of air sanitizers presents an effective solution to combat these invisible threats, providing cleaner, safer air for Homes, offices, Hospitals, social gatherings, Gyms, schools and public spaces. By harnessing advanced filtration, Uv technology, and active purification, air sanitizers help to reduce health risks significantly, promoting well being and ensuring that indoor air quality supports, rather than harms, human health. Its time we should prioritize the air we breathe as a fundamental step toward a healthier world.
