Air pollution Related Illnesses
You Should Know About
Clean air is a basic
precondition of our health. However, most of the people in United States and
other developed countries suffer from exposure to many air pollutants that put
our health at risk. Air pollution affects our health in different ways
from simple to serious problems. For example, particulate matter in the air decreases
life expectancy according to many researchers; Pollutants such as ozone
irritate people’s breathing, trigger asthma symptoms and cause lung and heart
diseases; exposure to environmental tobacco smoke causes many severe
respiratory health problems such as asthma and lung cancer. Prolonged exposure
to certain air pollutants can even cause human infertility according to recent
medical researches on air pollution.
Nowadays, scientists have discovered a lot of heart and
respiratory diseases related to air pollution; the most common are:
Minor Respiratory
Diseases - The best known is the cold, accompanied by symptoms such as sore
throats, congestion and runny nose, cough and sometimes irritation of eyes.
Respiratory tract Infections
– the most common are bronchitis and pneumonia, caused by viruses or bacteria.
They are characterized by cough, fever, chills and dyspnea
(difficulty breathing).
Asthma - Asthma
attacks can be triggered by various factors, including physical activity,
infections, exposure to pollen, allergies and stress. They can also be
triggered by sensitivity to non-allergenic pollutants in the air such as smog.
Chronic obstructive
pulmonary disease (COPD) - It includes two main troubles: emphysema and
chronic bronchitis. Emphysema is a chronic infection characterized by injuries
and loss of elasticity in the alveoli. Chronic bronchitis is characterized by
inflammation of the lining cells inside the airways, which increases the risk
of infection and blockage of the entry and exit of air from the lungs. While
other forms of air pollution can affect the development of these diseases,
Smoking is responsible for about 80% of cases of chronic obstructive pulmonary
disease.
Lung Cancer - It
is the leading cause of cancer deaths among women and men. Cigarette smoke
contains various carcinogens and is behind most cases of this fatal disease. Lung cancer typically doesn't cause
signs and symptoms in its earliest stages. When the disease is advanced
the symptoms of chronic cough, loss of appetite, wheezing and chest pain can
occur. Scientists have discovered a connection between air pollution and lung
cancer.
Coronary heart disease (CHD) -
disorders of the coronary arteries that are characterized by a narrowing or
blockage of arteries or blood vessels carrying blood and oxygen to the heart.
Cigarette Smoke (including second hand smoke), lack of exercise, obesity, high
cholesterol, family history of coronary artery disease and hypertension (high
blood pressure) are the main factors of this medical disorder.
Heart failure – is a problem that occurs when the
heart is unable to do its job, carry blood to the lungs and the rest of the
body. The most common cause is a serious disease of the coronary artery. It can
also be triggered by a sensitivity to non-allergenic pollutants in the air. The
main symptoms are shortness of breath and swollen ankles and feet.
Heart Arrhythmia (Irregular Heartbeat) - consists of irregular or
abnormal heartbeat. In some cases, arrhythmia is the result of coronary artery
disease. It can also be triggered by sensitivity to pollutants in the air. The
symptoms of arrhythmia are palpitations in the chest and dizziness. Certain
types of arrhythmia are dangerous and require emergency medical
treatment.
What can you do to prevent yourself from being a victim of
air pollution?
We can help. We believe in making air purifiers and air
cleaners that truly clean your air - not partially clean, but completely clean.
That’s why we believe that all indoor air purifiers need activated carbon in
addition to high quality HEPA filters. We use the largest activated carbon
filters in the industry to give you the most protection from chemicals and
odors. Particles like dust, pollen, mold, bacteria, and even viruses are all
removed indiscriminately by our HEPA air filter. Within our air cleaners, each
component is as inert as possible, designed to prevent toxic airborne chemicals
from ever being created. For more information on air pollution and air
cleaners, Visit our air
cleaners for home store.
