Respiratory health refers to the overall functioning and well-being of the respiratory system, including the lungs, airways, and other structures involved in breathing. Research in this area focuses on understanding and treating conditions that affect the respiratory system, such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer. This research also explores the impact of environmental factors, lifestyle choices, and genetics on respiratory health, as well as the development of new treatments and interventions to improve respiratory function and overall quality of life for individuals with respiratory conditions.
