2. Asthma
Respiratory illnesses such as asthma have increased greatly in the past few
decades. It is estimated that five percent of the population in the United States has
asthma. This is a chronic disease, that is, it affects a person over a long period of
time. It may begin before a child is 10 years old, or it may begin in adulthood.
Childhood asthma usually disappears around the age of 20, but adults who get it
later may have it all their lives.
People who suffer from asthma have difficulty breathing because the
airways in their lungs contract when a trigger causes a reaction. Among the
triggers of asthma are indoor and outdoor pollutants, according to doctors. Since
pollution has become more common, the number of people affected by this
disorder has risen. Indoor pollutants include cigarette smoke, dirt, insects, and
even pets like dogs or cats. Outdoor pollutants include chemicals, dust, and smog,
that is, smoke from factories or transport vehicles like buses and trucks.
People with asthma usually carry an inhaler in case of an attack. This
inhaler contains medicine that they breathe in, making the contracted airways in
the lungs expand so that they can breathe normally again. For a few people with
severe asthma, medicine can also be given by injection—in other words, it can be
applied under the skin with a needle every few weeks to prevent attacks.
While it is not possible to cure this condition, people who suffer from it are
advised to avoid pollutants. Parents with asthmatic children are told not to smoke
in the house and not to keep long-haired pets. They need to clean the house
frequently and keep it free of insects. Asthmatic adults are told to avoid outdoor
areas with a lot of pollution and working environments with a lot of chemicals.
Scientists continue to search for a cure for asthma, but instead of waiting
for one, people with asthma can take an active role in protecting themselves. By
avoiding asthma triggers, carrying an inhaler, living in a clean, smoke-free house,
and working in a pollutant-free place, they can live healthier lives.
