Causes Of Asthma

While there are several factors that are proven to have an impact on the likelihood of developing asthma, the exact cause of the condition is not known. What is known is that there are several predisposing factors that contribute to the chances of either a child or adult developing asthma in their lifetime, and that these factors are very often present in most homes, businesses and social areas.

There are also genetic and hereditary factors that can contribute to the chances of developing asthma. To understand the various factors, a list is provided below:

• Smoking by pregnant mothers increases the chances that the baby will develop asthma.
• Babies that are exposed to second hand smoke in their environment. Mothers, fathers or other adults smoking in the home can contribute to smoke in the house.
• Exposure to dust mites in the air. This is very common in well-kept houses that have carpets and little airflow through the home. Dry, warm conditions are prefect for dust mites. Bedding, furniture and toys can all trap both the dust mites and their waste products, which can be just as problematic.
• Animal and pet dander and hair in the environment.
• Pollen, molds and spores within the air or the environment.
• Dietary components. Foods that are high in salt, highly processed foods and lower amounts of Omega 3 fatty acids in diets may be linked to an increase in asthma.
• Decrease in the overall physical conditioning of most people. Physically fit individuals, even those with asthma, have less severe attacks than people that do not exercise frequently or are in poor physical condition.
• Chemicals, gasses, airborne irritants and other compounds in the air in workplace environments can cause asthma in adults, even if they did not have asthma during childhood.
• Genetic factors, such as a history of allergies or asthma in family members, especially parents or grandparents. Some conditions, such as eczema or chronic colds in parents, may also indicate an increased sensitivity to irritants that can become asthma in later life.

Some of the causes of asthma can be avoided, whereas others cannot. There is growing research that says that babies that are breastfed up to four months are less likely to have asthma or develop it later in life. There is also increasing research into children that are kept indoors all the time when they are very young. Because these children are never exposed to any bacteria or other irritants, the body does not develop a normal response to these irritants at an early age. The result is that the exposure when the child is older causes an extreme reaction, an allergic reaction, which can lead to asthma.
