The nervous system serves as a sophisticated communication network that regulates and coordinates the body's essential functions, including the respiratory system and lungs.

​

For instance, activities like climbing stairs, running, swimming, or biking occur seamlessly without conscious thought about breathing. This is because the respiratory center, located in the brain stem, adjusts breathing rates to meet the body's demands, ensuring stable oxygen and carbon dioxide levels, even during vigorous exercise.

​

Asthma affects both the lungs and the immune system and has emerged as one of the most prevalent and costly illnesses in the United States. Approximately 17 million Americans grapple with asthma, with an annual economic burden exceeding $13 billion.

 

Asthma-related hospitalizations surpass those of any other childhood ailment, with affected children missing over 10 million school days annually. Tragically, nearly 5000 lives are lost to asthma-related causes each year, contributing to its rising mortality rate.

​

Despite its common occurrence, asthma is a complex condition. During an asthma attack, the airways constrict and become obstructed due to a combination of muscle spasms, inflammation, and excessive mucus production.

 

Symptoms, which vary among individuals, encompass wheezing, shortness of breath, chest tightness, and chronic coughing.

​

Asthma attacks can be triggered by various factors that inflame the airways, including irritants such as dust mites, animal dander, pollen, mold, pollution, smoke, exercise, exposure to cold air, or intense emotions.
